Abstract

The basal ganglia are strongly involved in specific, motivation- and reward-mediated aspects of cortical processing: perception, cognition and action (Hikosaka et al., 1989). These aspects particularly concern “changes” in cortical activity modes (Mink and Thach, 1991), to which the basal ganglia contribute by “gating” of cortical and premotor activity via disinhibition (Chevalier and Deniau, 1990). The interactions between cortex and basal ganglia seem to be organized in multiple parallel loops (Alexander et al., 1986), with lateral competition between these loops as a possible mechanism for cortical cell assembly selection (Wickens et al., 1991).
