This study investigates brain response differences in fear learning in adult women at different phases of their menstrual cycle, in both healthy control and OCD groups. This is an in-person study located at Kincaid Hall at the University of Washington.<\/p>\n

This study will last approximately 3-4 hours over two consecutive days, 2-3 hours on day one and 0.5-1 hours on day two. You will complete a task while undergoing an MRI scan which involves viewing stimuli paired with a mild electric shock to the wrist. You will then complete some questionnaires about your physical and mental health history, mood, and demographic information.<\/p>\n

If you are interested in seeing if you are eligible for the study, you may complete our pre-screening survey on RedCap here: https:\/\/redcap.iths.org\/surveys\/?s=E7NMC9KRM7MLJW9R<\/a><\/p>\n
