Engagement of rat striatal neurons by cortical epileptiform activity investigated with paired recordingsEnrico Bracci
Department of Optometry and Neuroscience, University of Manchester Institute of Science Technology, Manchester M60 1QD, UK
J Neurophysiol 92:2725-37. 2004..Cholinergic interneurons located < 120 microm from simultaneously recorded MSs, did not display cortically driven bursts, suggesting that these cells are much less easily engaged by cortical epileptiform activity...
