DOI: 10.1111/adb.13258
Abstract: Adolescence is a vulnerable time for the acquisition of substance use disorders, potentially relating to ongoing development of neural circuits supporting instrumental learning. Striatal–cortical circuits undergo dynamic changes during instrumental learning and are implicated in… read more here.

DOI: 10.7554/elife.22169
Abstract: Catecholamines modulate the impact of motivational cues on action. Such motivational biases have been proposed to reflect cue-based, ‘Pavlovian’ effects. Here, we assess whether motivational biases may also arise from asymmetrical instrumental learning of active… read more here.
