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.

摘要

在稳定和不稳定的雄性日本鹌鹑配对中测量了攻击行为和全脑神经化学。在每日重新分组方案的第5天，攻击啄击达到峰值，并在第14天恢复到基础水平。在不稳定的配对中，攻击行为与脑去甲肾上腺素（NE）、多巴胺（DA）和乙酰胆碱酯酶（AChE）的增加有关。在不稳定和稳定的配对中，习惯化（12 - 15天）与DA对每日重新分组和饥饿的反应分别呈负相关。在不稳定的配对中，正常的全脑NE增加减弱。
