Incentive memory: evidence the basolateral amygdala encodes and the insular cortex retrieves outcome values to guide choice between goal-directed actions by Parkes, Shauna L, Balleine, Bernard W

“…Choice between goal-directed actions is determined by the relative value of their consequences. Such values are encoded during incentive learning and later…”

Contribution of dorsal versus ventral hippocampus to the hierarchical modulation of goal‐directed actions in rats by Piquet, Robin, Faugère, Angélique, Parkes, Shauna L.

“…Adaptive behaviour often necessitates that animals learn about events in a manner that is specific to a particular context or environment. These hierarchical…”
