Brain zaps may work better with hormones in mind

This study looks at how two types of non-invasive brain stimulation affect brain activity, and whether using them together works better than alone. The goal is to understand why brain stimulation for depression is less effective in women after menopause, possibly due to lower estrogen. 25 healthy adults aged 18-40 will attend up to 24 sessions over 8 months, with female participants scheduled at specific points in their menstrual cycle to track hormone changes.
