title: Agonistic behavior and neurochemistry in grouped Japanese quail.
abstract: Aggressive behavior and whole brain neurochemistry were measured in stable and unstable pairs of male Coturnix coturnix japonica. Aggressive pecking peaked on day 5 of the daily regrouping regime and returned to a basal level on day 14. Aggressive behavior was associated with increased brain norepinephrine (NE), dopamine (DA), and acetylcholinesterase (AChE) in unstable pairs. Habituation (12-15 days) and DA response to daily regrouping and inanition were inversely related in unstable and stable pairs respectively. Normal whole brain NE increases were attenuated in unstable pairs.
