Role of differential changes in sympathetic nerve activity in the preparatory adjustments of cardiovascular functions during freezing behaviour in rats

Freezing behaviour is associated with a distinct pattern of changes in cardiovascular function, which has been considered as a preparatory reflex for âfight or flight' behaviour. However, the detailed mechanisms underlying preparatory cardiovascular adjustments and their physiological implica...
