Neurodynamics

The investigators aim is to investigate the brain's dynamic complexity across three phases of an ovarian stimulation cycle (basal, pre-OPU, mid-luteal), to observe the impact of externally administered hormones, and compare it with the corresponding phases of a natural menstrual cycle (early follicular, pre-ovulatory, mid-luteal) in the same woman. Brain activity patterns will be examined using resting-state fMRI in a sample of young, healthy, naturally cycling women.
