Dopamine neurons drive spatiotemporally heterogeneous striatal dopamine signals during learning

Liv Engel, Amy R. Wolff, Madelyn L. Blake, Val L. Collins, Sonal Sinha, Benjamin T. Saunders

This study shows how dopamine signals in different striatal regions change during learning, with distinct patterns in nucleus accumbens core, shell, and dorsolateral striatum.

Contexts facilitate dynamic value encoding in the mesolimbic dopamine system

Kurt M. Fraser, Val L. Collins, Amy R. Wolff, David J. Ottenheimer, Kaisa N. Bornhoft, Fiona Pat, Bridget J. Chen, Patricia H. Janak, Benjamin T. Saunders

This study investigates how dopamine neurons in the mesolimbic system enable rapid revaluation of reward cues in changing environments using behavioral and neurophysiological methods in rats.

Cholinergic Interneurons Drive Motivation by Promoting Dopamine Release in the Nucleus Accumbens

Ali Mohebi, Val L. Collins, Joshua D. Berke

This study shows that cholinergic interneurons in the nucleus accumbens drive dopamine release, influencing motivated behavior in rats.

Hierarchical cue control of drug seeking in the face of cost

Val L. Collins, Kaisa N. Bornhoft, Amy R. Wolff, Sonal Sinha, Benjamin T. Saunders

This study investigates how patterns of drug intake and environmental cues influence relapse in rats, finding that binge-like cocaine intake predicts relapse despite escalating costs and that cues can hierarchically modulate drug-seeking behavior.
