Abstract
OBJECTIVE Sleep disorders are widespread and constitute a major public health risk. The present study thus aims to investigate the effect of a facial cosmetic self-massage daily routine on women's sleep and well-being. METHODS The present pilot study was conducted on 62 middle-aged women declaring daily tiredness and sleep troubles. We examined the effect of a regular facial cosmetic self-massage routine on sleep patterns, daytime sleepiness, and well-being over the course of 2 months. RESULTS After 1 and 2 months, our results show improved sleep quality (Pittsburgh Sleep Quality Index, PSQI - -20.2% after 2 months), reduced daytime sleepiness (Epworth Sleepiness Scale, ESS, -31.2% after 2 months), and increased well-being measures. The number of participants with abnormal sleep (PSQI >5) decreased over the course of the experiment as well, from 71.9% to 49.2% at the end of the 2 months [odds ratio 95% CI for decrease: 0.38 (0.18-0.81)]. Similarly, the number of participants with excessive daytime sleepiness (>10 on the ESS) decreased over the course of the study from 44.3% to 21% after 1 month [95% CI: 0.33 (0.15-0.73)] and to 16.1% after 2 months [95% CI: 0.24 (0.10-0.56)]. CONCLUSIONS These results suggest that a facial cosmetic self-massage routine may improve sleep patterns and is likely to be a useful addition to a standard sleep hygiene routine.

Abstract
Within vertebrates, central pattern generators drive rhythmical behaviours, such as locomotion and ventilation. Their pattern generation is also influenced by sensory input and various forms of neuromodulation. These capabilities arose early in vertebrate evolution, preceding the evolution of the cerebellum in jawed vertebrates. This later evolution of the cerebellum is suggestive of subsumption architecture that adds functionality to a pre-existing network. From a central-pattern-generator perspective, what additional functionality might the cerebellum provide? The suggestion is that the adaptive filter capabilities of the cerebellum may be able to use error learning to appropriately repurpose pattern output. Examples may include head and eye stabilization during locomotion, song learning, and context-dependent alternation between learnt motor-control sequences.

Abstract
In a complex social environment, stimuli from different sensory modalities need to be integrated to decode communicative meanings. From very early in life, infants have to combine a multitude of sensory features with social and affective attributes. Of all senses, touch constitutes a privileged channel to carry affective-motivational meanings and foster social connection. In the present study, we investigate whether sharing sensory stimulation that varies for its affective value differentially affects infants' attention towards visual stimuli. 6 to 11-month-old infants (N = 42) were familiarized with two characters respectively matched with tactile (affective or non-affective) and auditory stimulation; then repeatedly exposed to scenes where the two characters moved towards target objects. Our results showed a main effect of stimulation (sound vs. touch) on looking times during familiarization, with longer looking times when sound is provided. During scenes presentation, a main effect of the type of touch (affective vs. non affective) emerged, with longer looking times in infants that previously experienced affective touch, suggesting that this sensory experience may critically engage the self and modulate infant attention. Overall, these findings suggest that while sound acts as attention getter, affective touch supports sustained attention towards complex visual scenes beyond the stimulation period itself.

Abstract
Stimulating CT-afferents by forearm caresses produces the subjective experience of pleasantness in the receiver and modulates subjective evaluations of viewed affective images. Receiving touch from another person includes the social element of another person's presence, which has been found to influence affective image evaluations without involving touch. The current study investigated whether these modulations translate to facial muscle responses associated with positive and negative affect across touch-involving and mere presence conditions. Female participants (N = 40, M(age) = 22.4, SD = 5.3) watched affective images (neutral, positive, negative) while facial electromyography was recorded (sites: zygomaticus, corrugator). Results from ANOVAs showed that providing touch to another person or oneself modulated zygomaticus site responses when viewing positive images. Providing CT-afferent stimulating touch (i.e., forearm caresses) to another person or oneself dampened the positive affective facial muscle response to positive affective images. Providing touch to another person generally increased corrugator facial muscle activity related to negative affect. Receiving touch did not modulate affective facial muscle responses during the viewing of affective images but may have effects on later cognitive processes. Together, previously reported social and touch modulations of subjective evaluations of affective images do not translate to facial muscle responses during affective image viewing, which were differentially modulated.

Proc Biol Sci 2024; 291:20231753.

Abstract
Bodily self-awareness relies on a constant integration of visual, tactile, proprioceptive, and motor signals. In the 'rubber hand illusion' (RHI), conflicting visuo-tactile stimuli lead to changes in self-awareness. It remains unclear whether other, somatic signals could compensate for the alterations in self-awareness caused by visual information about the body. Here, we used the RHI in combination with robot-mediated self-touch to systematically investigate the role of tactile, proprioceptive and motor signals in maintaining and restoring bodily self-awareness. Participants moved the handle of a leader robot with their right hand and simultaneously received corresponding tactile feedback on their left hand from a follower robot. This self-touch stimulation was performed either before or after the induction of a classical RHI. Across three experiments, active self-touch delivered after-but not before-the RHI, significantly reduced the proprioceptive drift caused by RHI, supporting a restorative role of active self-touch on bodily self-awareness. The effect was not present during involuntary self-touch. Unimodal control conditions confirmed that both tactile and motor components of self-touch were necessary to restore bodily self-awareness. We hypothesize that active self-touch transiently boosts the precision of proprioceptive representation of the touched body part, thus counteracting the visual capture effects that underlie the RHI.

Abstract
While there is established evidence supporting the involvement of the sense of touch in various actions, the neural underpinnings of touch and action interplay in a social context remain poorly understood. To prospectively investigate this phenomenon and offer further insights, we employed a combination of motor and sensory components by asking participants to imagine exerting force with the index finger while experiencing their own touch, the touch of one another individual, the touch of a surface, and no touch. Based on the assumption that the patterns of activation in the motor system are similar when action is imagined or actually performed, we proceeded to apply a single-pulse transcranial magnetic stimulation over the primary motor cortex (M1) while participants engaged in the act of imagination. Touch experience was associated with higher M1 excitability in the presence and in the absence of force production imagination, but only during force production imagination M1 excitability differed among the types of touch: both biological sources, the self-touch and the touch of one other individual, elicited a significant increase in motor system activity when compared to touching a non-living surface or in the absence of touch. A strong correlation between individual touch avoidance questionnaire values and facilitation in the motor system was present while touching another person, indicating a social aspect for touch in action. The present study unveils the motor system correlates when the sensory/motor components of touch are considered in social contexts.

Abstract
Introduction Each individual touches the own body several 100 times a day. While some researchers propose a self-regulatory function of self-touch, others report that self-touching increases nervousness. This controversy appears to be caused by the fact that researchers did not define the kind of self-touch they examined and actually, referred to different types of self-touch. Thus, kinematically defining different types of self-touch, such as phasic (discrete), repetitive, and irregular, and exploring the neural correlates of the different types will provide insight into the neuropsychological function of self-touching behavior. Methods To this aim, we assessed hemodynamic responses in prefrontal brain areas using functional near-infrared spectroscopy (fNIRS) and behavioral responses with NEUROGES®. Fifty-two participants were recorded during three specific kinematically types of self-touch (phasic, irregular, repetitive) that were to be performed on command. The recently developed toolbox Satori was used for the visualization of neuronal processes. Results Behaviorally, the participants did not perform irregular self-touch reliably. Neurally, the comparison of phasic, irregular and repetitive self-touch revealed different activation patterns. Repetitive self-touch is associated with stronger hemodynamic responses in the left Orbitofrontal Cortex and the Dorsolateral Prefrontal Cortex than phasic self-touch. Discussion These brain areas have been reported to be associated with self-regulatory processes. Furthermore, irregular self-touch appears to be primarily generated by implicit neural control. Thus, by distinguishing kinematically different types of self-touch, our findings shed light on the controverse discussion on the neuropsychological function of self-touch.

Abstract
BACKGROUND Caress-like touch activates C-tactile (CT) afferents present in the skin of humans. It is generally assumed that this type of touch provides beneficial effects throughout the lifespan. However, little is known about its processing in later adulthood. Moreover, emotional responses to interpersonal vs. self-touch have not been investigated in older adults. METHOD A total of 132 females from two age groups (older: 60-96 years; younger: 18-30) participated in a well-validated method of tactile stimulation, in which CT-optimal vs. nonoptimal soft brushing (3 cm/s vs. 30 cm/s) was administered on the forearms of the participants, once by a female experimenter and once by the participant themselves. All participants rated their affective state in each of the conditions and tactile acuity was assessed. RESULTS Relative to the younger group, older participants rated touch as more pleasant, independent of type (CT-optimal, non-optimal) and origin (experimenter, self). In the older group, the emotional differentiation of CT-optimal vs. non-optimal touch was reduced, which was associated with reduced tactile acuity. CONCLUSION This study revealed an age-dependent enhancement of the perceived pleasantness of (self)touch. Interventions with auditory-guided CT-optimal self-touch could be easily implemented as part of training programs for older adults.

Abstract
INTRODUCTION The tactile sense plays a crucial role in the development and maintenance of a functional bodily self. The ability to differentiate between self- and nonself-generated touch contributes to the perception of the bodies' boundaries and more generally to self-other-distinction, both of which are thought be altered in anorexia nervosa (AN) and autism spectrum condition (AS). While it has been suggested that AN and AS are characterized by overlapping symptomatology, they might differ regarding body perception and self-other-distinction. METHODS Participants with a diagnosis of AN (n = 25), AS (n = 29), and a comparison group without diagnoses (n = 57) performed a self-other-touch task during functional brain imaging. In the experimental conditions, they stroked their own arm or were stroked on the arm by an experimenter. RESULTS As shown previously, the CG group showed lower activation or deactivation in response to self-touch compared to social touch from someone else. A main group effect was found in areas including somatosensory cortex, frontal and temporal gyri, insula, and subcortical regions. This was driven by increased activations in participants with AN, while participants in the AS group showed mostly comparable activations to the comparison group. CONCLUSIONS AN diagnosis was associated with an increased neural activity in response to both self-touch and social touch. Failure to attenuate self-touch might relate to altered predictions regarding the own body and reduced perception of bodily boundaries. Participants with an AS diagnosis were mostly comparable to the comparison group, potentially indicating unaltered tactile self-other-distinction.

Abstract
This study examined how touch role and culture shape affective touch experiences. Germans (N = 130) and Chinese (N = 130) were surveyed once as toucher and once as touchee. For different touch actions, they (a) provided free-text descriptions of what prompts touch, (b) indicated with whom touch feels comfortable, and (c) highlighted areas of touch comfort on a body outline. Overall, touch was prompted by affectionate feelings, was more comfortable with more closely bonded individuals, and when directed at the upper arms, shoulders, and upper back. Touch role mattered for the experiences prompting touch in that touchees felt less positive than touchers. Culture differentiated touch comfort topographies. Compared with Chinese, Germans felt more comfortable with more intimate touch to the torso and upper back and less comfortable with more public touch to the hands. Notably, however, examining touch role and culture revealed more overlap than divergence, ensuring mutual comfort as individuals physically connect.
