The need for power,brain norepinephrine turnover,and memory

Subjects were classified according to whether they were high or low in the need for Power and high or low in gain in 3-methoxy-4-hydroxyphenylglycol (MHPG), a putative index of brain norepinephrine (NE) turnover, after engaging in some tasks that involved memory for story content. Subjects who were high inn Power and in the index of brain NE turnover showed better recall of power-related facts than subjects low on both these characteristics, confirming an earlier finding, which suggests that the need for Power is subserved by a noradrenergic reward system in the brain.
