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 striatal fiber photometry signals mainly reflect non-somatic calcium changes, not somatic ones.

This study shows that obese mice exhibit increased activity in D1R-expressing spiny projection neurons in the nucleus accumbens during food seeking, which enhances food motivation and contributes to diet-induced obesity.

This study identifies a specific subpopulation of ventral pallidal neurons that modulate nucleus accumbens firing to enhance reward consumption.

This study shows that LRRK2-G2019S mutation alters behavioral and synaptic responses to acute social stress in mice, suggesting impaired adaptive plasticity in neural circuits linked to psychopathology.

This study shows orexin signaling in GABAergic lateral habenula neurons promotes aggression and conditioned place preference, suggesting a potential therapeutic target for reducing aggressive behaviors.
