Abstract
Translocator protein (TSPO) is involved in several cellular mechanisms such as steroidogenesis, immunomodulation, cell proliferation and differentiation. Overexpressed in several neurodegenerative diseases and brain cancer, TSPO radioligands have been developed over the last 20 years in positron emission tomography (PET) imaging. Recently, TSPO radioligands have extended beyond their initial application due to their specific binding to activated macrophages, making them a compelling biomarker for deciphering the intricacies of the tumor microenvironment (TME). In this review, we synthesized recent progress from the evaluation of TSPO-specific PET tracers in various peripheral tumor models and highlighted the hurdles and limitations associated with heterogeneous uptake in healthy tissue and tumor regions to achieve the clinical development of such a radiotracer.

Abstract
OBJECTIVES The article aims to describe tobacco and e-cigarette use among pregnant women: estimate the prevalence, identify the determinants and motivations of these behaviours. METHODS Cross-sectional, multicentre, descriptive observational study using self-administered questionnaires for pregnant women who visited ELENA healthcare centers in May 2021. RESULTS Of 223 patients, 38% were smokers before pregnancy and 16% continued to smoke during pregnancy. Nearly all the smokers (98%) declared that they had reduced or stopped their tobacco use, mostly without help. Young age, lack of professional activity, an unfavourable reaction to the announcement of the pregnancy, heavy smoking before the pregnancy and the presence of a smoker spouse were associated with smoking during pregnancy. Our study identified 10% of vapers before pregnancy and 7.2% during pregnancy. Of those who vaped during pregnancy, 81% were smokers before pregnancy. Most of them used a nicotine containing liquid and 38% of vapers combined smoking and e-cigarettes during pregnancy. There was no association between vaping during pregnancy and smoking cessation. A minority of women had received information about smoking during pregnancy. CONCLUSIONS The use of electronic cigarettes by pregnant women is a poorly-known reality in France, yet it concerns approximately 7% of the women in our sample. Prospective studies on larger numbers are needed to assess the prevalence of vaping among French pregnant women and its evolution during pregnancy.

Abstract
BACKGROUND Children in Afghanistan live in dangerous areas, and have been exposed to traumatic events and chaotic education. Progress has been made on access to education for girls who were the most affected by traditional attitudes against engagement in education. OBJECTIVES The objectives were to evaluate the mental health of Afghan children living in regions of conflict and the association of mental health with school attendance for girls and boys. METHOD The study included 2707 school aged children in eight regions of Afghanistan (16 provinces) residing in households recruited through a multi-stage stratified cluster sampling strategy in 2017. The level of terrorist threat was evaluated by the intensity of terrorist attacks recorded that year in each province. Child mental health was assessed with the parental report Strengths and Difficulties Questionnaire (SDQ) along with information on school attendance, sociodemographic characteristics and geographic location. RESULTS A total of 52.75% of children had scores above threshold for the SDQ total difficulties score, 39.19% for emotional difficulties, 51.98% for conduct challenges, and 15.37% for hyperactivity/inattention. Peer relationship problems were high (82.86%) and 12.38% reported that these problems impacted daily life. The level of terrorist threat was associated with SDQ total difficulties (Adjusted Odds Ratio [AOR] = 4.08, P < 0.0001), with youth in regions with high levels of terrorist threat more likely to have problems than youth in regions with low or medium levels of danger, independent of region and ethnicity. School attendance was negatively associated with emotional symptoms (AOR = 0.65, P < 0.0001) and mental health difficulties with impairment (AOR = 0.67, P = 0.007), but positively associated with peer relationships difficulties (AOR = 1.96, P > 0.0001). Conduct (AOR = 1.66, P < .0001) and SDQ total difficulties (AOR = 1.22, P = 0.019) were higher among boys. Overall, gender did not modify the relationship between school attendance and child mental health. CONCLUSION Attending school is essential for children's mental health, across gender, and should be supported as a priority in Afghanistan despite the return of the Taliban.

Abstract
In the management of prostate cancer in recent years, innovative therapies have appeared requiring precise and reliable disease detection. In 2021, new generation imaging (PET/CT, multiparametric MRI, PET/MRI) have their place at all stages of the prostate cancer natural history to help target the lesion(s) and guide therapy and improve the results obtained. PSMA PET/CT is currently the leader in this type of imaging with a complete offer during the disease: both from diagnosis, to recurrence or in the oligo-metastatic and metastatic stage resistant to castration with a pivotal role in the PSMA theranostic approach. However, multiparametric MRI also has many detection advantages when the prostate is left in place, which suggests the potential major benefit of hybrid PSMA PET/MRI imaging.

Abstract
OBJECTIVE Diagnosis and therapeutics are challenging in pregnancy-related breast cancer and a multidisciplinary approach is therefore essential. A nomogram predictive of recurrence at 36 months of PABC has recently been developed, the aim was to evaluate it on an independent cohort. PATIENTS AND METHODS This was a monocentric retrospective study including all patients with PABC between January 2004 and March 2018. A Kaplan-Meier method was used for the analysis of recurrence-free survival. Nomogram performance was analysed on 3 indicators: discrimination by a receiver operator characteristic curve (ROC), calibration and net clinical benefit by a decision curve analysis. RESULTS Forty-one patients have been included. The survival rate was 83 % at 3 years. The nomogram showed acceptable discrimination capacities on receiver-operator characteristic analysis (c-index: 0.78). Decision-curve analysis showed a positive net-benefit for relapse probability ranges between 5 % and 35 %. CONCLUSION The performance of this prediction model is acceptable but the net clinical benefit low. In conclusion, prediction of recurrence remains challenging with a continued need for more precise tools.

Abstract
Movements rely on a mixture of feedforward and feedback mechanisms. With experience, the brain builds internal representations of actions in different contexts. Many factors are taken into account in this process among which is the immutable presence of gravity. Any displacement of a massive body in the gravitational field generates forces and torques that must be predicted and compensated by appropriate motor commands. The insular cortex is a key brain area for graviception. However, no attempt has been made to address whether the same internal representation of gravity is shared between feedforward and feedback mechanisms. Here, participants either mentally simulated (only feedforward) or performed (feedforward and feedback) vertical movements of the hand. We found that the posterior part of the insular cortex was engaged when feedback was processed. The anterior insula, however, was activated only in mental simulation of the action. A psychophysical experiment demonstrates participants' ability to integrate the effects of gravity. Our results point toward a dual internal representation of gravity within the insula. We discuss the conceptual link between these two dualities.

Abstract
Delayed defecation is common in patients on intensive care. We aimed to determine factors associated with time to defecation after admission to intensive care and in turn its association with length of stay and mortality. We studied 396 adults admitted to one of five intensive care units in whom at least 2 days' invasive ventilation was anticipated during an expected stay of at least 3 days. The median (IQR [range]) time to defecate by the 336 out of 396 (84%) patients who did so before intensive care discharge was 6 (4-8 [1-18]) days. Defecation was independently associated with five factors, hazard ratio (95%CI), higher values indicating more rapid defecation: alcoholism, 1.32 (1.05-1.66), p = 0.02; laxatives before admission, 2.35 (1.79-3.07), p < 0.001; non-invasive ventilation, 0.54 (0.36-0.82), p = 0.004; duration of ventilation, 0.78 (0.74-0.82), p < 0.001; laxatives after admission, 1.67 (1.23-2.26), p < 0.001; and enteral nutrition within 48 h of admission, 1.43 (1.07-1.90), p = 0.01. Delayed defecation was associated with prolonged intensive care stay but not mortality.

Abstract
Multicenter studies are needed to demonstrate the clinical potential value of radiomics as a prognostic tool. However, variability in scanner models, acquisition protocols and reconstruction settings are unavoidable and radiomic features are notoriously sensitive to these factors, which hinders pooling them in a statistical analysis. A statistical harmonization method called ComBat was developed to deal with the "batch effect" in gene expression microarray data and was used in radiomics studies to deal with the "center-effect". Our goal was to evaluate modifications in ComBat allowing for more flexibility in choosing a reference and improving robustness of the estimation. Two modified ComBat versions were evaluated: M-ComBat allows to transform all features distributions to a chosen reference, instead of the overall mean, providing more flexibility. B-ComBat adds bootstrap and Monte Carlo for improved robustness in the estimation. BM-ComBat combines both modifications. The four versions were compared regarding their ability to harmonize features in a multicenter context in two different clinical datasets. The first contains 119 locally advanced cervical cancer patients from 3 centers, with magnetic resonance imaging and positron emission tomography imaging. In that case ComBat was applied with 3 labels corresponding to each center. The second one contains 98 locally advanced laryngeal cancer patients from 5 centers with contrast-enhanced computed tomography. In that specific case, because imaging settings were highly heterogeneous even within each of the five centers, unsupervised clustering was used to determine two labels for applying ComBat. The impact of each harmonization was evaluated through three different machine learning pipelines for the modelling step in predicting the clinical outcomes, across two performance metrics (balanced accuracy and Matthews correlation coefficient). Before harmonization, almost all radiomic features had significantly different distributions between labels. These differences were successfully removed with all ComBat versions. The predictive ability of the radiomic models was always improved with harmonization and the improved ComBat provided the best results. This was observed consistently in both datasets, through all machine learning pipelines and performance metrics. The proposed modifications allow for more flexibility and robustness in the estimation. They also slightly but consistently improve the predictive power of resulting radiomic models.

Abstract
OBJECTIVE The innate immune system plays a central role in osteoarthritis (OA). We identified 14-3-3ε as a novel mediator that guides chondrocytes toward an inflammatory phenotype. 14-3-3ε shares common characteristics with alarmins. These endogenous molecules, released into extracellular media, are increasingly incriminated in sustaining OA inflammation. Alarmins bind mainly to toll-like receptor 2 (TLR2) and TLR4 receptors and polarize macrophages in the synovium. We investigated the effects of 14-3-3ε in joint cells and tissues and its interactions with TLRs to define it as a new alarmin involved in OA. DESIGN Chondrocyte, synoviocyte and macrophage cultures from murine or OA human samples were treated with 14-3-3ε. To inhibit TLR2/4 in chondrocytes, blocking antibodies were used. Moreover, chondrocytes and bone marrow macrophage (BMM) cultures from knockout (KO) TLRs mice were stimulated with 14-3-3ε. Gene expression and release of inflammatory mediators [interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor alpha (TNFα)] were evaluated via reverse transcription quantitative polymerase chain reaction (RT-qPCR) and ELISA. RESULTS In vitro, 14-3-3ε induced gene expression and release of IL6 and MCP1 in the treated cells. The inflammatory effects of 14-3-3ε were significantly reduced following TLRs inhibition or in TLRs KO chondrocytes and BMM. CONCLUSIONS 14-3-3ε is able to induce an inflammatory phenotype in synoviocytes, macrophages and chondrocytes in addition to polarizing macrophages. These effects seem to involve TLR2 or TLR4 to trigger innate immunity. Our results designate 14-3-3ε as a novel alarmin in OA and as a new target either for therapeutic and/or prognostic purposes.

Abstract
AbstractThe objective of the survey was to compare depressive symptoms in depression with and without a concomitant organic disease. The results based on the HAD and CES-D scales showed that, compared to those with an isolated depression, the patients with an associated chronic organic disease have a higher score on two items on the HAD. Three variables on the CES-D scale also helped to differentiate the two groups of depressed patients. No significant difference was found between the two groups in terms of anxiety or cognitive symptoms, fatigue or feelings of disability. Our results do not indicate any symptom that is specific to a combination of depression and somatic diseases. Guilt and hostility showed a lower level in depression associated with a concomitant somatic disease than in isolated depression.

Abstract
INTRODUCTION The new 2018 international guidelines for diagnosing usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF) by CT scan split the old pattern possible UIP (2011 IPF guidelines) into two new patterns: probable UIP and indeterminate for UIP. However, the proportions and prognoses of these new CT-scan patterns are not clear. METHODS We used a monocentric retrospective cohort of 322 patients suspected of having IPF (University Hospital of Rennes; Competence Center for Rare Lung Diseases; 1 January 2012-31 December 2017). All patients initially diagnosed by CT scan as possible UIP were included. The chest CT-scans were then reclassified according to the new 2018 international guidelines by 3 observers. These data were then subjected to survival analysis with multivariate Cox regression using a composite endpoint of death, lung transplantation, a decline of≥10% in forced vital capacity (FVC), or hospitalization. RESULTS Of the 89 possible UIP patients included, 74 (83%) were reclassified as probable UIP and 15 (17%) as indeterminate for UIP. Probable UIP patients were more likely to meet the composite endpoint (56/74 [75.7%] vs. 5/15 [33%] patients; HR [IC 95%] =3.12 [1.24; 7.83], P=0.015). Multivariate analysis indicated that the probable UIP pattern was associated with significantly increased risk of reaching the composite endpoint (HR [95% CI]=2.85[1.00; 8.10], P=0.049). CONCLUSION The majority of possible UIP diagnoses corresponded to probable UIP, which was associated with a significantly worse prognosis than indeterminate for UIP. This distinction between these two CT patterns emphasizes the relevance of the new international guidelines for the diagnosis of IPF.

Abstract
BACKGROUND AND PURPOSE The reasons for poor clinical outcome after thrombectomy for acute stroke, concerning around half of all patients, are misunderstood. We developed a hierarchic algorithm based on DWI to better identify patients at high risk of disability. MATERIALS AND METHODS Our single-center, retrospective study included consecutive patients with acute ischemic stroke who underwent thrombectomy for large anterior artery occlusion and underwent pretreatment DWI. The primary outcome was the mRS at 3 months after stroke onset. Multivariable regression was used to identify independent clinical and imaging predictors of poor prognosis (mRS > 2) at 3 months, and a hierarchic algorithm predictive of disability was developed. RESULTS A total of 149 patients were analyzed. In decreasing importance, DWI lesion volume of >80 mL, baseline NIHSS score of >14, age older than 75 years, and time from stroke onset to groin puncture of >4 hours were independent predictors of poor prognosis. The predictive hierarchic algorithm developed from the multivariate analysis predicted the risk of disability at 3 months for up to 100% of patients with a high predictive value. The area under the receiver operating characteristic curve was 0.87. CONCLUSIONS The DWI-based hierarchic algorithm we developed is highly predictive of disability at 3 months after thrombectomy and is easy to use in routine practice.

Abstract
BACKGROUND The aim of our study was to evaluate the diversity, or homogeneity, of recommendations made in multidisciplinary team meetings (MTM) concerning the management of facial skin cancers in France, and to analyze the determinants thereof. PATIENTS AND METHODS We contacted a panel of dermatology and ENT multidisciplinary teams (MDT) and collected their recommendations made at meetings regarding 3 clinical cases: squamous cell carcinoma in a renal transplant patient with an incomplete excision margin (case 1), locally advanced basal cell carcinoma (case 2), and lentigo maligna (case 3). The responses were analyzed globally and then based on 2 subgroups defined by the presence or absence of a dermatologist in the MTM. The effect of the makeup of the MTM (based on the presence of a dermatologist, a plastic surgeon, an oncologist and an ENT specialist) was evaluated for the main therapeutic proposals. RESULTS The opinions of the 45 MDMs that responded to the survey were mixed for the three cases as regards important elements such as the indication of surgical revision for case 1, the proposal of an alternative treatment to surgery for case 2, and monitoring arrangements for case 3. Certain proposals were associated with the presence of a dermatologist in the MTM, such as discussion of adaptation of immunosuppressive treatment and details of the surgical margins to be applied for case 1, as well as simple monitoring and details of monitoring arrangements in case 3. CONCLUSION It is important to maintain dermatologists in MTMs on account of their expertise in all therapeutic areas concerning skin cancers.

Abstract
The objective of this cross-sectional survey was to assess the prevalence of psychoactive substance use (PSU) in people attending 11 French Sexual Transmitted Infection Centers, and to specify their profiles (PSU and link with risky sexual behaviors) using the ascending hierarchical clustering method. Among the 5220 individuals who completed the survey, 55.6% were men and the median age was 24 years [IQR: 20-31]. Among the participants, 2751 (52.7%) reported PSU at least once in their life. Ascending hierarchical clustering identified seven distinct profiles of participants based on their PSU. This study shows a high prevalence of PSU and alcohol consumption in this young population. Moreover, subgroup analysis allowed identifying groups of psychoactive substance users who presented specific risks or vulnerabilities and who should be priority targets for interventions, particularly sexual minority groups.

Abstract
AIM We explored the associations between childhood exposure to screens, including televisions, computers, game consoles, tablets and smartphones and primary language disorders. METHODS This multi-centre case-control study comprised 167 children aged 3.5-6.5 years, who were born in 2010-2012 and diagnosed with primary language disorders, and 109 matched controls without language disorders. Questionnaires were completed by their parents who were recruited by 16 family doctors and 27 speech and language therapists in the Ille-et-Vilaine region of France. The data were analysed using a multivariate logistic regression model and presented as adjusted odds ratios (aOR) and 95% confidence intervals (95% CI). RESULTS We found that cases (44.3%) and controls (22.0%) exposed to screens in the morning before nursery or primary school were three times more likely to develop primary language disorders (aOR 3.40, 95% CI 1.60-7.23). When this risk was combined with rarely or never discussing screen content with their parents (aOR 2.14, 95% CI 1.01-4.54) they were six times more likely to have language problems (aOR 5.86, 95% CI 1.44-23.95). CONCLUSION Being exposed to screens in the morning before school, and rarely or never discussing screen content with parents, meant children were six times more likely to develop primary language disorders.

Abstract
Introduction In June 2012, the government of Canada severely restricted the scope of the Interim Federal Health Program that had hitherto provided coverage for the health care needs of refugee claimants. The Quebec government decided to supplement coverage via the provincial health program. Despite this, we hypothesized that refugee claimant children in Montreal would continue to experience significant difficulties in accessing basic health care. Objectives (1) Report the narrative experiences of refugee claimant families who were denied health care services in Montreal following June 2012, (2) describe the predominant barriers to accessing health care services and understanding their impact using thematic analysis and (3) derive concrete recommendations for child health care providers to improve access to care for refugee claimant children. Methods Eleven parents recruited from two sites in Montreal participated in semi-structured interviews designed to elicit a narrative account of their experiences seeking health care. Interviews were recorded, transcribed, coded using NVivo software and subjected to thematic analysis. Results Thematic analysis of the data revealed five themes concerning barriers to health care access: lack of continuous health coverage, health care administrators/providers' lack of understanding of Interim Federal Health Program coverage, refusal of services or fees charged, refugee claimants' lack of understanding about health care rights and services and language barriers, and four themes concerning the impact of denial of care episodes: potential for adverse health outcomes, psychological distress, financial burden and social stigma. Conclusion We propose eight action points for advocacy by Canadian paediatricians to improve access to health care for refugee claimant children in their communities and institutions.

Abstract
BACKGROUND Multidrug-resistant Acinetobacter baumannii (MR-AB) can cause outbreaks in a burns unit. AIM To study the incidence, risk factors and outcome of MR-AB colonization during an outbreak. METHODS A prospective study was conducted from April to November 2014 in a burns unit in Paris. Weekly surveillance cultures of patients and their environment were performed. MR-AB acquisition, discharge, or death without MR-AB colonization were considered as competing events. To identify risk factors for colonization, baseline characteristics and time-dependent variables were investigated in univariate and multivariate analyses using Cox models. MR-AB strains were genotypically compared using multi-locus sequence typing. FINDINGS Eighty-six patients were admitted in the burns unit during the study period. Among 77 patients without MR-AB colonization at admission, 25 (32%) acquired MR-AB with a cumulative incidence of 30% at 28 days (95% CI: 20-40). Median time to MR-AB acquisition was 13 days (range: 5-34). In multivariate analysis, risk factors for MR-AB acquisition were ≥2 skin graft procedures performed [hazard ratio (HR): 2.97; 95% confidence interval (CI): 1.10-8.00; P = 0.032] and antibiotic therapy during hospitalization (HR: 4.42; 95% CI: 1.19-16.4; P = 0.026). A major sequence type of MR-AB (ST2) was found in 94% and 92% of patients and environmental strains, respectively, with all strains harbouring the blaOXA-23 gene. MR-AB colonization increased length of hospitalization (HR: 0.32; 95% CI: 0.17-0.58; P = 0.0002) by a median of 12 days. CONCLUSION A high incidence of MR-AB acquisition was seen during this outbreak with most strains from patients and their environment belonging to single sequence type. MR-AB colonization was associated with more skin graft procedures, antibiotic use, and prolonged hospitalization.

Abstract
Whether the central nervous system is capable to switch between contexts critically depends on experimental details. Motor control studies regularly adopt robotic devices to perturb the dynamics of a certain task. Other approaches investigate motor control by altering the gravitoinertial context itself as in parabolic flights and human centrifuges. In contrast to conventional robotic experiments, where only the hand is perturbed, these gravitoinertial or immersive settings coherently plunge participants into new environments. However, radically different they are, perfect adaptation of motor responses are commonly reported. In object manipulation tasks, this translates into a good matching of the grasping force or grip force to the destabilizing load force. One possible bias in these protocols is the predictability of the forthcoming dynamics. Here we test whether the successful switching and adaptation processes observed in immersive environments are a consequence of the fact that participants can predict the perturbation schedule. We used a short arm human centrifuge to decouple the effects of space and time on the dynamics of an object manipulation task by adding an unnatural explicit position-dependent force. We created different dynamical contexts by asking 20 participants to move the object at three different paces. These contextual sessions were interleaved such that we could simulate concurrent learning. We assessed adaptation by measuring how grip force was adjusted to this unnatural load force. We found that the motor system can switch between new unusual dynamical contexts, as reported by surprisingly well-adjusted grip forces, and that this capacity is not a mere consequence of the ability to predict the time course of the upcoming dynamics. We posit that a coherent flow of multimodal sensory information born in a homogeneous milieu allows switching between dynamical contexts.

Abstract
During summer 2016, all the conditions for local mosquito-borne transmission of Zika virus (ZIKV) are met in mainland France: a competent vector, Aedes albopictus, a large number of travellers returning from ZIKV-affected areas, and an immunologically naive population. From 1 January to 15 July 2016, 625 persons with evidence of recent ZIKV infection were reported in mainland France. We describe the surveillance system in place and control measures implemented to reduce the risk of infection.

Abstract
To elaborate a motor plan and perform online control in the gravity field, the brain relies on priors and multisensory integration of information. In particular, afferent and efferent inputs related to the initial state are thought to convey sensorimotor information to plan the upcoming action. Yet it is still unclear to what extent these cues impact motor planning. Here we examined the role of initial information on the planning and execution of arm movements. Participants performed upward arm movements around the shoulder at three speeds and in two arm conditions. In the first condition, the arm was outstretched horizontally and required a significant muscular command to compensate for the gravitational shoulder torque before movement onset. In contrast, in the second condition the arm was passively maintained in the same position with a cushioned support and did not require any muscle contraction before movement execution. We quantified differences in motor performance by comparing shoulder velocity profiles. Previous studies showed that asymmetric velocity profiles reflect an optimal integration of the effects of gravity on upward movements. Consistent with this, we found decreased acceleration durations in both arm conditions. However, early differences in kinematic asymmetries and EMG patterns between the two conditions signaled a change of the motor plan. This different behavior carried on through trials when the arm was at rest before movement onset and may reveal a distinct motor strategy chosen in the context of uncertainty. Altogether, we suggest that the information available online must be complemented by accurate initial information.

Abstract
We isolated 11 antibodies specific for canine CD138 (cCD138) to validate the interest of CD138 antigen targeting in dogs with spontaneous mammary carcinoma. The affinity of the monoclonal antibodies in the nanomolar range is suitable for immunohistochemistry and nuclear medicine applications. Four distinct epitopes were recognized on cCD138 by this panel of antibodies. CD138 expression in canine healthy tissues is comparable to that reported in humans. CD138 is frequently expressed in canine mammary carcinomas corresponding to the human triple negative breast cancer subtype, with cytoplasmic and membranous expression. In canine diffuse large B-cell lymphoma, CD138 expression is associated with the 'non-germinal center' phenotype corresponding to the most aggressive subtype in humans. This homology of CD138 expression between dogs and humans confirms the relevance of tumour-bearing dogs as spontaneous models for nuclear medicine applications, especially for the evaluation of new tumour targeting strategies for diagnosis by phenotypic imaging and radio-immunotherapy.

Abstract
The planning of any motor action requires a complex multisensory processing by the brain. Gravity - immutable on Earth - has been shown to be a key input to these mechanisms. Seminal fMRI studies performed during visual perception of falling objects and self-motion demonstrated that humans represent the action of gravity in parts of the cortical vestibular system; in particular, the insular cortex and the cerebellum. However, little is known as to whether a specific neural network is engaged when processing non-visual signals relevant to gravity. We asked participants to perform vertical and horizontal hand movements without visual control, while lying in a 3T-MRI scanner. We highlighted brain regions activated in the processing of vertical movements, for which the effects of gravity changed during execution. Precisely, the left insula was activated in vertical movements and not in horizontal movements. Moreover, the network identified by contrasting vertical and horizontal movements overlapped with neural correlates previously associated to the processing of simulated self-motion and visual perception of the vertical direction. Interestingly, we found that the insular cortex activity is direction-dependent which suggests that this brain region processes the effects of gravity on the moving limbs through non-visual signals.
