Description:
Kainic acid lesion of cell bodies in the dorsal striatum enhanced the stereotypy-producing effects of d-amphetamine without affecting the sterotypy produced by the direct receptor agonist apomorphine. This pattern of results parallels that found in patients suffering from Hungtington's chorea, thus strengthening the parallels between the kainic acid animal model and the human disease state initially suggested on biochemical gounds. The present results further suggest a dissociation of the mechanisms involved in the production of stereotypy by these two drugs, perhaps in terms of differential involvement of the striato-nigral negative feedback loop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mason, S T -- Sanberg, P R -- Fibiger, H C -- New York, N.Y. -- Science. 1978 Jul 28;201(4353):352-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26976" target="_blank"〉PubMed〈/a〉
