Design outcomes

Primary

MeasureTime frame
To study the effects of 10 minutes of Unilateral Right Nostril Breathing and Unilateral Left Nostril Breathing on Cortical Silent Period (CSP) using TMS-EMG in patients with Major Depressive DisordersTimepoint: Baseline, 5 minutes after intervention

Secondary

MeasureTime frame
