The effect of psychedelics on associative learning: a systematic review

This systematic review examines the effects of psychedelics on associative learning in humans and animals, finding enhanced learning in animals but inconsistent results and methodological heterogeneity.

Appetite for change: How nutritional state and ventral striatal dopamine shape psilocybin effects on cognitive flexibility

This study shows psilocybin improves cognitive flexibility in rats under food restriction but not after anorexia exposure, with changes in striatal dopamine signaling.

Psilocybin modulates social behaviour in male and female mice in a time-dependent manner

This study shows psilocybin affects social behavior in male and female mice differently over time, with sex-specific changes in social preference and dopamine signaling.

Acute threats modulate hunger circuit dynamics to instruct avoidance behaviour

This study shows that hunger-sensitive AgRP neurons in the hypothalamus are inhibited by threats, leading to avoidance behavior through GABAergic inputs from DMH neurons.

Psilocybin exerts differential effects on social behaviour and inflammation in mice in contexts of activity-based anorexia (ABA)

This study examines psilocybin's effects on social behavior and inflammation in female mice under different stress conditions, finding context-dependent changes in novelty-seeking and IL-6 levels.

Toward a genetic signature of resistance to activity-based anorexia in striatal projecting cortical neurons

The paper identifies transcriptional differences in striatal projecting cortical neurons that distinguish rats susceptible from resistant to activity-based anorexia, linking gene expression patterns to metabolic and neural functions.

FiPhoPHA - A fiber photometry python package for post-hoc analysis

FiPhoPHA provides a user-friendly Python package for unbiased post-hoc statistical analysis of fiber photometry data, improving reproducibility and standardization.

Psilocybin increases optimistic engagement over time: computational modelling of behavior in rats

This study uses computational models to show that psilocybin increases reward acquisition in rats by enhancing task engagement through altered forgetting rates and reduced loss aversion.

Psilocybin prevents activity-based anorexia in female rats by enhancing cognitive flexibility: contributions from 5-HT1A and 5-HT2A receptor mechanisms.

This study shows psilocybin improves cognitive flexibility and body weight in female rats with activity-based anorexia, mediated by 5-HT1A and 5-HT2A receptor mechanisms.

Temporal regulation of AgRP neurons mediates context-induced feeding

This study shows that AgRP neurons regulate context-induced feeding through precise temporal firing patterns during context exposure.

Identification of a stress-sensitive anorexigenic neurocircuit from medial prefrontal cortex to lateral hypothalamus.

The paper identifies a stress-sensitive anorexigenic pathway from the medial prefrontal cortex to the lateral hypothalamus in mice and shows its role in regulating food intake during stress.

Suppression of cortico-striatal circuit activity improves cognitive flexibility and prevents body weight loss in activity-based anorexia in rats
