Electrophysiological, microiontophoretic and neuroanatomical techniques have been employed to investigate the relationships between intrastriatal sites of dopamine/glutamate (DA/GLU) interaction and inhomogeneities for acetylcholinesterase. The sites where iontophoretically applied DA antagonized the excitatory effects of iontophoretic GLU or cortical stimulation showed no topographic arrangement in the dorsolateral parts of the striatum. The data suggest that DA/GLU interaction in the striatum of the adult rat may occur independently from distribution of acetylcholinesterase.

Abstract
Electrophysiological, microiontophoretic and neuroanatomical techniques have been employed to investigate the relationships between intrastriatal sites of dopamine/glutamate (DA/GLU) interaction and inhomogeneities for acetylcholinesterase. The sites where iontophoretically applied DA antagonized the excitatory effects of iontophoretic GLU or cortical stimulation showed no topographic arrangement in the dorsolateral parts of the striatum. The data suggest that DA/GLU interaction in the striatum of the adult rat may occur independently from distribution of acetylcholinesterase.File in questo prodotto:
