Ethylcholine aziridinium ion (AF64A), a putative specific cholinergic neurotoxin, was unilaterally injected into the substantia nigra of male rats. One week following injection, rats that were challenged with apomorphine exhibited ipsilateral circiling behavior. After two weeks, rats were sacrificed and corpus striatum and combined n.accumbens plus o. tubercle were assayed for dopamine. Striatal dopamine levels were depleted by 50%. Histological examination showed that AF64A caused extensive damage at the injection site. These data indicate that injection of AF64A into the substantia nigra can result in damage to dopaminergic neurons.
