abstract = {This study investigates the brain’s response to virtual sexual content using EEG dynamic cross-entropy and physiological measures of arousal. It aims to elucidate the neural underpinnings of “sexual presence”—a state of arousal influenced by personal predispositions and technological affordances. The research integrates concepts of sexual affordances within embodied cognitive processes, suggesting that the brain optimizes responses to minimize free energy when processing sexual cues. The findings show that sexual avatars trigger specific arousal and attention, evidenced by physiological arousal responses. Notably, frontal cross-entropy in the low alpha band decreased during exposure to sexual content, suggesting a more streamlined frontal information transfer during arousal. The results contribute to understanding how virtual environments can induce sexual presence, indicating that sexual affordances in virtual settings significantly influence cognitive engagement and neural efficiency. The study’s outcomes have implications in the understanding of human-machine interactions with virtual content mobilizing sexual cognition. © 2024. Published by AHFE.},

This study investigates the brain’s response to virtual sexual content using EEG dynamic cross-entropy and physiological measures of arousal. It aims to elucidate the neural underpinnings of “sexual presence”—a state of arousal influenced by personal predispositions and technological affordances. The research integrates concepts of sexual affordances within embodied cognitive processes, suggesting that the brain optimizes responses to minimize free energy when processing sexual cues. The findings show that sexual avatars trigger specific arousal and attention, evidenced by physiological arousal responses. Notably, frontal cross-entropy in the low alpha band decreased during exposure to sexual content, suggesting a more streamlined frontal information transfer during arousal. The results contribute to understanding how virtual environments can induce sexual presence, indicating that sexual affordances in virtual settings significantly influence cognitive engagement and neural efficiency. The study’s outcomes have implications in the understanding of human-machine interactions with virtual content mobilizing sexual cognition. © 2024. Published by AHFE.

Exposure to chronic stress disrupts blood-brain barrier integrity; still, little is known about intestinal barrier function in these conditions, particularly for the small intestine, where absorption of most foods and drugs takes place. Methods: We investigated how chronic social or variable stress, two mouse models of depression, impact the jejunum intestinal barrier in males and females. Mice were subjected to stress paradigms followed by analysis of gene expression profiles of intestinal barrier–related targets, fecal microbial composition, and blood-based markers. Results: Altered microbial populations and changes in gene expression of jejunum tight junctions were observed depending on the type and duration of stress, with sex-specific effects. We used machine learning to characterize in detail morphological tight junction properties, identifying a cluster of ruffled junctions in stressed animals. Junctional ruffling is associated with inflammation, so we evaluated whether lipopolysaccharide injection recapitulates stress-induced changes in the jejunum and observed profound sex differences.
