Overview
The purpose of the proposed study is to broaden our understanding on the neural effects of High Definition Transcranial Direct Current Stimulation (HD-tDCS) so that its clinical effects can be further improved.
Description
Normal healthy individuals will be recruited and undergo a standardized neuropsychological assessment (ANAM, MoCA, BDI-II, ToMS, and MAAS) and magnetic resonance imaging (MRI). During MRI, HD-tDCS will be applied. Four different stimulation targets will be investigated, and subjects will be randomly assigned for each target groups or sham group. After HD-tDCS/MRI session, subjects will be re-assessed with standardized neuropsychological tests.
Eligibility
