Following an initial period
of instrumental
training, BAC WT and BAC MT mice were tested for their ability to discriminate 2 complex visual stimuli (discrimination
phase), where nosepokes to the correct touchscreen stimulus were rewarded by delivery
of a sweetened 14 mg food pellet reward, and nosepokes to the incorrect touchscreen stimulus resulted in a brief blackout period where the screens became inoperative, followed by
correction trials until the correct response was made.
