Thus, the proposed study has the following Specific Aims and Hypotheses:
1. To determine in menstruating women ages 18-45 whether an OCP containing ethinyl
estradiol (EE) and the progestin ethinydiol diacetate (ED) increases cortical GABA
concentrations as measured using proton magnetic resonance spectroscopy (1H-MRS) above

2. To determine the relationship between changes in occipital GABA concentrations with
acute OCP administration and negative affect with chronic OCP administration over two
