Primary Outcome Measures

Name	Time	Method
For patients with mood disorders,<br>1) Severity assessment of mood disorders: evaluate changes after each session by PANAS, and changes after all the sessions by HRSD or BDI-II.<br>2) Assessment of changes in brain activity associated with the treatment effects: evaluate changes in brain activity (changes in signals of each brain region on fMRI, EEG and NIRS before and after the treatment) associated with the treatment effects, such as in severity of mood disorders (assessed by HRSD or BDI-II).<br>For healthy controls,<br>3) Viability assessment of manipulation of neural activity: evaluate the desired brain activity or functional connectivity patterns by brain functional imaging to check whether they can be induced or not.
