title: Time course of the changes of catecholamine levels in rat brain during swimming stress.
abstract: The time course of the changes in the levels of adrenaline, noradrenaline and dopamine was investigated in rat hypothalamus, ponsmedulla and midbrain during 4-h swimming at 35 degrees C. The adrenaline levels showed gradual decrease whereas the noradrenaline and dopamine levels were kept in almost steady-state during the swimming. These findings suggest that brainstem adrenaline levels are not so fast adaptive as the noradrenaline and dopamine levels under the stress.
