Figure 1. Schematic illustration of the behavioural training and testing schedule post-surgery. Animals received a sequence of alternation sessions that involved preceding intracerebral infusions of either clozapine or saline. There was also an additional infusion-free session. After the four sessions, rats moved onto the next T-maze condition, starting with training sessions followed by infusion sessions. The order of infusions was counterbalanced across the two cohorts as indicated.
