Changes in brain monoamine metabolism of neonatal chicks under two different acute stress conditions

Abstract

1. The purpose of the present study was to clarify brain monoamine metabolism during two different conditions of acute stress by quantifying changes in the brain of neonatal chicks exposed to either restraint with isolation, or fasting stress.

2. Under restraint with isolation-induced stress, dopaminergic metabolism was clearly stimulated.

3. During fasting stress, dopaminergic activity, serotonergic and norepinephrinergic metabolisms were stimulated.

4. It was concluded that brain monoamine metabolism of chicks is differentially affected by stressors.
