The study examines the effects of unilateral quisqualic acid nucleus basalis (NB) lesioning on cortical EEG and learning behavior. Lesions produced both gliosis in the ventral pallidum and a marked reduction in the cortical ChAT activity. Normal cortical EEG activity was abolished on the side of NB lesion, i.e., slow wave activity and the incidence of high(More)
The present study investigates whether the stimulation of gamma-aminobutyric acid (GABA)ergic system affects spatial navigation deficits induced by the lesioning of the nucleus basalis (NB). Thus, the effect of gamma-vinyl-GABA treatment which elevates the GABA levels in brain was studied on water maze task both in unoperated and NB-lesioned (ibotenic acid)(More)
