Murphy et al . 36 found that during the treatment process for menopause disorder by estrogen replacement (such as estradiol), expression of the GABA receptor, GAD of the hippocampus neuron, and synthesis of GABA decreased in the rat brain Even for alcoholism, the GABA content in plasma decreased and the symptoms of neurosis (anorexia, sense of pain) and mental disorder (depression, mania, anxiety) were significant 37 Therefore, supply of GABA and enhancement of activity of the GABA receptor improve depression 30,31
