Abstract
Brain reward dysfunction in eating disorders has been widely reported. However, whether the neural correlates of hedonic and motivational experiences related to food cues are differentially affected in anorexia nervosa of restrictive type (ANr), bulimia nervosa (BN), and healthy control (HC) participants remains unknown. Here, 39 women (14 ANr, 13 BN, and 12 HC) underwent fMRI while smelling food or non-food odors in hunger and satiety states during liking and wanting tasks. ANr and BN patients reported less desire to eat odor-cued food and odor-cued high energy-density food (EDF), respectively. ANr patients exhibited lower ventral tegmental area (VTA) activation than BN patients to food odors when rating their desire to eat, suggesting altered incentive salience attribution to food odors. Compared with HC participants, BN patients exhibited decreased activation of the caudate nucleus to food odors in the hunger state during the wanting task. Both patient groups also showed reduced activation of the anterior ventral pallidum and insula in response to high EDF odors in the hunger state during the wanting task. These findings indicate that brain activation within the food reward-regulating circuit differentiates the three groups. ANr patients further exhibited lower activation of the precuneus than other participants, suggesting a possible role of body image distortion in ANr. Our study highlights that food odors are relevant sensory probes to gain better insight into the dysfunction of the mesolimbic and striatal circuitry involved in food reward processing in patients with EDs.

Neurosci Biobehav Rev 2016; 73:326-339. [PMID: 28024828 DOI: 10.1016/j.neubiorev.2016.12.028] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 12/09/2016] [Accepted: 12/20/2016] [Indexed: 02/04/2023]
Abstract
The differential susceptibility model states that a given genetic variant is associated with an increased risk of pathology in negative environments but greater than average resilience in enriched ones. While this theory was first implemented in psychiatric-genetic research, it may also help us to unravel the complex ways that genes and environments interact to influence feeding behavior and obesity. We reviewed evidence on gene vs. environment interactions that influence obesity development, aiming to support the applicability of the differential susceptibility model for this condition, and propose that various environmental "layers" relevant for human development should be considered when bearing the differential susceptibility model in mind. Mother-child relationship, socioeconomic status and individual's response are important modifiers of BMI and food intake when interacting with gene variants, "for better and for worse". While only a few studies to date have investigated obesity outcomes using this approach, we propose that the differential susceptibility hypothesis is in fact highly applicable to the study of genetic and environmental influences on feeding behavior and obesity risk.

Abstract
The study of food aversion in humans by the induction of illness is ethically unthinkable, and it is difficult to propose a type of food that is disgusting for everybody. However, although cheese is considered edible by most people, it can also be perceived as particularly disgusting to some individuals. As such, the perception of cheese constitutes a good model to study the cerebral processes of food disgust and aversion. In this study, we show that a higher percentage of people are disgusted by cheese than by other types of food. Functional magnetic resonance imaging then reveals that the internal and external globus pallidus and the substantia nigra belonging to the basal ganglia are more activated in participants who dislike or diswant to eat cheese (Anti) than in other participants who like to eat cheese, as revealed following stimulation with cheese odors and pictures. We suggest that the aforementioned basal ganglia structures commonly involved in reward are also involved in the aversive motivated behaviors. Our results further show that the ventral pallidum, a core structure of the reward circuit, is deactivated in Anti subjects stimulated by cheese in the wanting task, highlighting the suppression of motivation-related activation in subjects disgusted by cheese.

Better quality of mother-child interaction at 4 years of age decreases emotional overeating in IUGR girls. Appetite 2014; 81:337-42. [PMID: 25014742 DOI: 10.1016/j.appet.2014.06.107] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2014] [Revised: 06/24/2014] [Accepted: 06/29/2014] [Indexed: 11/21/2022]
Abstract
BACKGROUND/OBJECTIVES While most "fetal programming" area focused on metabolic disease, intrauterine growth restriction (IUGR) is also associated with a preference for less healthy food. Post-natal factors such as strained maternal-child interactions are equally related to obesogenic eating behaviors. We investigated if IUGR and the quality of the mother/child relationship affect emotional overeating in children. SUBJECTS/METHODS Participants were 196 children from a prospective birth cohort (the MAVAN project). As part of the protocol at 4 years of age, mothers completed the Children Eating Behavior Questionnaire (CEBQ) and mother-child interactions were scored during a structured task. A GLM adjusted for BMI examined the interaction between the "Atmosphere" score (ATM) task, sex and IUGR on the emotional over-eating domain of the CEBQ. RESULTS There was a significant interaction of BWR vs. sex vs. ATM (P = .02), with no effects of IUGR, sex or ATM. The model was significant for girls with low ATM scores (B = -2.035, P = .014), but not for girls with high (P = 0.94) or boys with high (P = .27) or low (P = .19) ATM scores. Only in IUGR girls, 48 months emotional over-eating correlated with BMI at that age (r = 0.560, P = 0.013) and predicted BMI in the subsequent years (r = 0.654, P = 0.006 at 60 months and r = 0.750, P = 0.005 at 72 months). CONCLUSIONS IUGR and exposure to a negative emotional atmosphere during maternal-child interactions predicted emotional overeating in girls but not in boys. The quality of mother-infant interaction may be an important target for interventions to prevent emotional overeating and overweight in early development, particularly in girls with a history of IUGR.

Abstract
Brain reward systems mediate liking and wanting for food reward. Here, we explore the differential involvement of the following structures for these two components: the ventral and dorsal striatopallidal area, orbitofrontal cortex (OFC), anterior insula and anterior cingulate. Twelve healthy female participants were asked to rate pleasantness (liking of food and non-food odors) and the desire to eat (wanting of odor-evoked food) during event-related functional magnetic resonance imaging (fMRI). The subjective ratings and fMRI were performed in hunger and satiety states. Activations of regions of interest were compared as a function of task (liking vs wanting), odor category (food vs non-food) and metabolic state (hunger vs satiety). We found that the nucleus accumbens and ventral pallidum were differentially involved in liking or wanting during the hunger state, which suggests a reciprocal inhibitory influence between these structures. Neural activation of OFC subregions was correlated with either liking or wanting ratings, suggesting an OFC role in reward processing magnitude. Finally, during the hunger state, participants with a high body mass index exhibited less activation in neural structures underlying food reward processing. Our results suggest that food liking and wanting are two separable psychological constructs and may be functionally segregated within the cortico-striatopallidal circuit.
