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.

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.

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.

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

This study shows that requiring mice to perform a simple action to access high-fat diet reduces intake and prevents obesity, suggesting that easy access promotes overeating.

This study shows that GHSRs in the olfactory bulb link hunger to olfactory sensitivity, affecting food-seeking and metabolism in mice.

This study shows that metabolic sensing in AgRP neurons is essential for dopamine release in the nucleus accumbens in response to caloric solutions and influences sucrose preference under hunger.

This study shows that ghrelin signaling in AgRP neurons integrates energy need with sensory cues to regulate AgRP activity and dopamine release in response to food.

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

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.

This study shows that impaired metabolic-sensing in AgRP neurons reduces dopamine release in the dorsal striatum and suppresses reward-seeking behavior, especially under hunger.

This study examines how body weight and energy homeostasis affect effective connectivity between hypothalamic regions using resting-state fMRI in humans.

The paper uses neural network modeling to show increased top-down excitation from the insula to the hypothalamus and reduced prefrontal cortex excitation in obesity, regardless of hunger state.

The paper shows that elevated circulating unacylated-ghrelin impairs hippocampal neurogenesis and memory in mice and is associated with reduced AG:UAG ratio in Parkinson’s disease dementia patients.

This study investigates how ventral striatopallidal neurons modulate orexin/hypocretin neuron activity in response to food and metabolic states, revealing their role in reward-seeking behavior.
