Dopaminergic and cholinergic influences on motor behavior in chickens.


The dopamine receptor agonist apomorphine enhanced motor activity as measured in stabilimeters and decreased the duration of tonic immobility behavior in chickens in a dose-dependent manner. Haloperidol, a dopamine receptor antagonist, increased the duration of tonic immobility and attenuated the apomorphine-induced increase in activity. Motor activity… (More)
