EEG activity generated in the entorhinal cortex and hippocampus of control rats (CTL group) at PD60 with i.c.v. infusion of 4-AP (3 nmol), KB-R7943 (62.5 pmol) or the combination of 4-AP (3 nmol) and KB-R7943 (62.5 pmol). Representative one-minute fragments from the recordings taken during basal activity (5 min before the infusion), at the onset of altered activity, and 30 and 60 min after completion of the infusion are presented
