Vulnerability and Resilience to Activity-Based Anorexia is Not Sex-Dependent

This study shows that male and female mice exhibit similar vulnerable and resilient phenotypes in activity-based anorexia, suggesting sex differences in anorexia prevalence may be due to sociocultural factors rather than biology.

Striatal signaling tracks naturalistic short-term fluctuations in hunger-satiety

This study examines how dopamine signaling in the nucleus accumbens changes during naturalistic feeding, showing transient increases during food approach that diminish with ingestion and recover between meals.

Accumbal Dopamine and Acetylcholine Dynamics during Psychostimulant Sensitization

This study investigates how dopamine and acetylcholine dynamics in the nucleus accumbens change with repeated psychostimulant exposure and finds that D2 receptor signaling on cholinergic interneurons is critical for sensitization of neural responses but not for behavioral sensitization.

Dietary regulation of silent synapses in the dorsolateral striatum

This study shows that dietary-induced obesity increases silent synapses in the dorsolateral striatum, similar to drugs of abuse, suggesting shared mechanisms in neural circuit remodeling.

Opposing Motor Memories in the Direct and Indirect Pathways of the Basal Ganglia

The paper identifies distinct memory storage in the direct and indirect basal ganglia pathways, showing normal motor memory is preserved in the direct pathway while aberrant inhibitory memory is stored in the indirect pathway.
