Bilateral infusion of the GABAA-receptor agonist muscimol into the basal forebrain was previously found to impair visual conditional discrimination performance in rats. In order to examine whether the GABAergic input into the basal forebrain is active during performance of this task, the benzodiazepine receptor agonist chlordiazepoxide (15, 25, 40 micrograms/0.5 microliters/hemisphere) was bilaterally infused. Surprisingly, chlordiazepoxide did not affect performance. The impact of this result for the understanding of basal forebrain GABAergic functions is discussed.
