The Functional Neuroanatomy of the Human Physiological Stress Response

Description

The purpose of this study is to examine the effect of a moderately low blood sugar stress on the nervous system. The investigators hope that information obtained from completing this study will help to reveal information about how a non-psychological stress impacts the parts of the brain that react to stress and the autonomic nervous system. The autonomic nervous system is the part of the nervous system that provides the body with involuntary or automatic control of heart rate, blood pressure, and breathing.
