ABSTRACT
The influence of emotion on human memory is associated with two contradictory effects in the form either emotion-induced enhancements or decrements memory. In a series experiments involving single word presentation, we show that enhanced for emotional words strongly coupled to items preceding stimulus, an effect more pronounced women. These would appear depend common neurobiological substrate, and are reversed by propranolol, beta-adrenergic antagonist, abolished selective bilateral amygdala damage. Thus, our findings suggest amygdala-dependent modulation episodic encoding has costs as well benefits.
