Figure 2From: Nucleus accumbens core lesions retard instrumental learning and performance with delayed reinforcement in the ratSchematic of lesions of the AcbC Black shading indicates the extent of neuronal loss common to all subjects; grey indicates the area lesioned in at least one subject. Coronal sections are (from top to bottom) +2.7, +2.2, +1.7, +1.2, and +0.7 mm relative to bregma. Diagrams are modified from reference [83]. Panels a-c correspond to Experiment 1, in which lesions were made before training; panels d-f correspond to Experiment 2, in which lesions were made after initial training. Panels a & d show groups trained with no delays; panels b & e show groups trained with 10 s delays; panels c & f show groups trained with 20 s delays.Back to article page
