Blockade of NMDA receptors in the dorsomedial striatum prevents action-outcome learning in instrumental conditioning.
Although there is consensus that instrumental conditioning depends on the encoding of action-outcome associations, it is not known where this learning process is localized in the brain. Recent research suggests that the posterior dorsomedial striatum (pDMS) may be the critical locus of these associations. We tested this hypothesis by examining the contribution of N-methyl-D-aspartate receptors ...

Introduction: The dorsal striatum plays an important role in the control of motor activity and learning processes within the basal ganglia circuitry. Furthermore, recent works have suggested functional differentiation between subregions of the dorsal striatum Methods: The present study examined the effects of bilateral electrolytic lesions of the dorsomedial striatum on motor behavior and learn...
متن کاملThe role of the dorsomedial striatum in instrumental conditioning.
Considerable evidence suggests that, in instrumental conditioning, rats learn the relationship between actions and their specific consequences or outcomes. The present study examined the role of the dorsomedial striatum (DMS) in this type of learning after excitotoxic lesions and reversible, muscimol-induced inactivation. In three experiments, rats were first trained to press two levers for dis...

متن کاملContralateral disconnection of the rat prelimbic cortex and dorsomedial striatum impairs cue-guided behavioral switching.
Switches in reward outcomes or reward-predictive cues are two fundamental ways in which information is used to flexibly shift response patterns. The rat prelimbic cortex and dorsomedial striatum support behavioral flexibility based on a change in outcomes. The present experiments investigated whether these two brain regions are necessary for conditional discrimination performance in which a swi...
