Amygdala aromatase controls food intake, reward, and thermoregulation.

Summary: Did you know your brain makes its own estrogen? Scientists found that an enzyme called aromatase, which produces estrogen, is highly active in a part of the brain called the amygdala. When researchers blocked this enzyme in rats, the results were completely different for males and females! Female rats started eating more high-fat foods, gained weight, and had lower body temperatures. On the flip side, male rats actually ate less and got warmer. This amazing discovery shows that brain-made estrogen is super important for controlling our appetite, weight, and body heat. Since some common medications block this enzyme, this research could help doctors better understand their side effects in humans.
