Effects of single and long-term haloperidol administration on open field behavior of rats.

abstract：:Normal unoperated rats were tested for rotation (i.e., circling behavior) in a spherical "rotometer" and dose-response relationships were generated using d-amphetamine, apomorphine, L-Dopa, haloperidol, and scopolamine. The rotation induced by amphetamine was significantly antagonized by alpha-methyl-p-tyrosine and ha...
