“…Furthermore, reduced correlations between the somatosensory and visual network has been observed with increasing bulimia symptoms 67 . These findings taken along with our own suggest that the relationship between earlier onset of puberty and adult BMI may be related to increased sensory‐driven behaviours but decreased bodily perception 33,65,67 . Similarities between functional correlations in individuals who went through puberty early and disordered eating are in line with previous research demonstrating that being more developmentally advanced compared to one's peers is a risk factor for disordered eating in adolescence and adulthood, 68‐70 specifically for the clinical diagnosis of bulimia nervosa 71 .…”

Onset of puberty has been associated with lower body mass index (BMI) in adulthood independent of childhood BMI. However, how the relationship between time of onset of puberty and BMI in adulthood is associated with neurocognitive outcomes is largely unstudied. Here, women were sampled from the Human Connectome Project 1200 PTN release. Inclusion criteria were: 4 (15 minute) resting state fMRI scans, current measured BMI, self-reported age at onset of menstruation (a proxy of age at onset of puberty), and no endocrine complications (e.g., polycystic ovarian syndrome). The effect of age at onset of menstruation, measured BMI at scan date, and the interaction of age at onset of menstruation by BMI on brain functional correlation was modeled using FSLnets controlling for race and age at scan. Corrected significance was set at pFWE<0.05. A final sample of n=510 (age 29.5y±3.6; BMI at scan 25.9±5.6; age at onset of menstruation 12.7±1.6) were included. Age at onset of menstruation was negatively associated with BMI at scan (r=-0.19, p<0.001). The interaction between age at onset of menstruation and BMI at scan was associated with stronger correlation between a somatosensory and visual network (t= 3.45, pFWE= 0.026), and a visual network and cinguloopercular task control network (t= 4.74, pFWE= 0.0002). We show increased correlation between visual, taste-associated, and self-control brain regions in women at high BMI with later age at onset of menstruation. Together, this implies that the association between later menarche and lower BMI may impart improved self-control during exposure to visual cues.

As source of sensory information, the body provides a sense of agency and self/non-self-discrimination. The integration of bodily states and sensory inputs with prior beliefs has been linked to the generation of bodily self-consciousness. The ability to detect surprising tactile stimuli is essential for the survival of an organism and for the formation of mental body representations. Despite the relevance for a variety of psychiatric disorders characterized by altered body and self-perception, the neurobiology of these processes is poorly understood. We therefore investigated the effect of psilocybin (Psi), known to induce alterations in self-experience, on tactile mismatch responses by combining pharmacological manipulations with simultaneous electroencephalography–functional magnetic resonance imaging (EEG–fMRI) recording. Psi reduced activity in response to tactile surprising stimuli in frontal regions, the visual cortex, and the cerebellum. Furthermore, Psi reduced tactile mismatch negativity EEG responses at frontal electrodes, associated with alterations of body- and self-experience. This study provides first evidence that Psi alters the integration of tactile sensory inputs through aberrant prediction error processing and highlights the importance of the 5-HT2A system in tactile deviancy processing as well as in the integration of bodily and self-related stimuli. These findings may have important implications for the treatment of psychiatric disorders characterized by aberrant bodily self-awareness.
