['It has been argued that tasks that necessitate the use of context in the service of goal-directed behaviour are disrupted in both schizophrenic patients and in animal analogues by dopamine (DA) manipulation with the prefrontal cortex being implicated.', 'To determine the effects on conditional discrimination performance of direct infusion of the DA D(1)/D(2) receptor antagonist alpha-flupenthixol into the medial prefrontal cortex (mPFC) and of its reversal potential on d-amphetamine-induced task disruption.', 'Conditional discrimination performance in which rats learn to respond on an appropriate lever, conditional upon specific auditory stimuli, was acquired and later tested under the above drug treatment protocol in extinction.', 'Conditional discrimination performance was unaffected by bilateral intra-mPFC alpha-flupenthixol at doses of 12, 24 or 36 microg/microl. A dose of D-amphetamine (1.5 mg/kg) shown previously to disrupt conditional discrimination performance was attenuated by direct PFC infusion of alpha-flupenthixol at doses of 24 and 36 but not 12 microg/microl per site.'] Does medial prefrontal cortex infusion of alpha-flupenthixol attenuate systemic d-amphetamine-induced disruption of conditional discrimination performance in rats?
