Ventral striatum lesions do not affect reinforcement learning with deterministic outcomes on slow time scales.
R Vicario-Feliciano, EA Murray… - Behavioral …, 2017 - psycnet.apa.org
A large body of work has implicated the ventral striatum (VS) in aspects of reinforcement
learning (RL). However, less work has directly examined the effects of lesions in the VS, or …

Choice suppression through opponent but not independent function of the striatal indirect pathway
The dorsomedial striatum (DMS) plays a key role in action selection, but little is known about

Dopaminergic signalling during goal-directed behaviour in a structured environment
M Blanco Pozo - 2022 - ora.ox.ac.uk
During flexible behaviour, dopamine is thought to carry reward prediction errors (RPEs),
which update values and hence modify future behaviour. However, in real-world situations …
