Dr. Nicole Petersen is an assistant professor in the department of psychiatry and behavioral sciences at UCLA. Her commentary is a new paper in the journal Neuropsychopharmacology, called “Spotlighting SHAPERS: sex hormones associated with psychological and endocrine roles.” Dr. Petersen starts the paper describing an unnamed signaling molecule that can affect the physical structure of the brain and that seems to be related to a wide number of psychological and neurological conditions. Then she reveals that this is estradiol. The point she makes in the paper is that estrogen isn’t the only neuroactive substance that affects the brain in ways that we just don’t understand.
