Study Summary

The purpose of this study is to investigate the role of brain receptors called alpha2-adrenoreceptors in regulating the sympathetic nervous system, which maintains the supply of blood and fuel to the body's organs in times of stress, fear, anger, or exercise. Alpha(2)-adrenergic receptors (alpha(2)-AR) play a role in a variety of physiological functions. There are three subtypes of alpha(2)-ARs, and their differences are unknown. This study will examine the functional roles of these three subtypes by comparing the behavioral, biochemical, psychophysiological, and autonomic function effects of the alpha(2)-AR drugs clonidine and yohimbine. Participants in this study will undergo a physical examination, electrocardiogram (ECG), and blood, urine, and saliva tests. Women will have hormone tests to determine the time of their last period and the time of their next ovulation. Participants will undergo neuropsychological testing and other procedures.
