Estrogens and Cognition Online Study

University of Toronto, Department of Psychology, The Einstein Lab of Cognitive Neuroscience, Gender and Health

The Einstein Lab at the University of Toronto is looking for participants to help investigate the effects of estrogens on cognition. We are very interested in how the removal of the ovaries (oophorectomy) as an effort to prevent the onset of cancer, can affect the way we think, our memory, and attention.
