Schematic drawings of coronal sections of the rat brain adapted from the atlas of Paxinos and Watson (1986), showing the location of the dialysis surface of probes in either the nucleus accumbens (ventral striatum; a) or dorsolateral caudate nucleus (dorsal striatum; b). Probe locations in control (saline-pretreated) animals are shown on the left-hand side of each section and those in amphetamine-pretreated animals on the right-hand side of each section.
