Double dissociation of the effects of selective nucleus accumbens core and shell lesions on impulsive-choice behaviour and salience learning in rats

The nucleus accumbens can be subdivided into at least two anatomically distinct subregions: a dorsolateral ‘core’ and a ventromedial ‘shell’, and this distinction may extend to a functional dissociation. Here, we contrasted the effects of selective excitotoxic core and medial shell lesions on impuls...
