To assess the possible involvement of catecholaminergic neurotransmitters in maintenance of spatial cognition, the present work investigated the effects of dopaminergic and noradrenergic receptor antagonists on memory performance of rats in a partially baited radial eight-arm maze. Food-deprived rats were first trained to enter the arms baited with chocolate, and each subject was then randomly assigned to receive further training in either a place version or a cue version of the task.
