The striatum is a key brain region involved in reward processing. Striatal activity has been linked to encoding rewardmagnitude and integrating diverse reward outcome information. Recent work has supported the involvement ofstriatum in the valuation of outcomes. The present work extends this idea by examining striatal activity during dynamicshifts in value that include different levels and directions of magnitude disparity. A novel task was used to produce
diverse relative reward effects on a chain of instrumental action. Rats (Rattus norvegicus) were trained to respond to
cues associated with specific outcomes varying by food pellet magnitude. Animals were exposed …
