Localization of acetylcholinesterase activity at synapses of the rat striatum during the stages of recovery after inhibition in vivo.
A pharmacohistological method was used to study the ultrastructural localization of acetylcholinesterase in the rat striatum. Five hours after administration of an organophosphorous inhibitor (paraoxon), high activities of this enzyme were selectively found in some neurons and at numerous axo-spinous synapses of the asymmetrical type. The cholinergic nature of these synapses appeared unlikely.
