Results show that lesions of the dorsomedial, but not of the dorsolateral CPu increased reaction times. These findings provide further evidence for a functional heterogenity of the CPu and demonstrate an involvement of the dorsomedial CPu in processes related to rapid initiation of responseseninfo:eu-repo/semantics/openAccessBasalganglien , Reaktionszeit , Ratte570Reaction time , Locomotor initiation , Dorsomedial caudate , putamen , Dorsolateral caudate , putamen , Striatal heterogeneity , Ratarticle2012-12-05
