Aim of the research was to study the possible relationship between rapid apomorphine-induced modifications of midbrain dopaminergic neuron activity and rapid modifications of a motor response triggered by sensory stimuli (sensory-motor integration. Following apomorphine administration, ANOVA test revealed significant decrease of head turning latency and duration. A change on dopamine release, leading to an inhibition or facilitation of dopamine-mediated responses to environmental stimuli, may be hypothesized.
