title: Motor effects of copper in the caudate nucleus: reversible lesions with ion-exchange resin beads.
abstract: A method employing the use of ion-exchange resin beads is described for the punctate introduction of discrete amounts of various anions, cations, or zwitterions into given brain regions. A series of experiments utilizing the method to introduce ionic copper into the caudate nucleus with the resulting motor manifestations are discussed.
