title: A reexamination of apomorphine induced stereotypy in the rat in light of self administration experiments.
abstract: 1. Apomorphine is known to both elicit stereotypy and to support behavioral self administration. The present report examined a possible contribution of stereotypy to self administration. 2. Non-contingent intraperitoneal injection of apomorphine in adult male Sprague-Dawley rats immediately prior to their placement in an experimental chamber significantly elevated barpressing above operant rates. 3. This indicates a novel dopamine induced behavior which may play a role in determining self administration behavior. 4. The data suggest three interpretations of previous self administration experiments.
