High-Definition Transcranial Direct Current Stimulation for Activation of the Target Brain Region

Abstract

Source: Chen, W., et al. Stimulation Location Determination using a 3D Digitizer with High-Definition Transcranial Direct Current Stimulation. J. Vis. Exp. (2019)

This video demonstrates the procedure for delivering high-definition transcranial direct current stimulation (HD-tDCS) by accurately positioning electrodes using the 10–10 system, mapping their locations with a 3D digitizer, and applying stimulation to modulate neuronal activity in a targeted brain region.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.

1. Stimulation
   1. Make sure that the participants have no contraindications (e.g., a history of neurological or psychiatric disorders) for HD-tDCS (high-definition transcranial direct current stimulation) and that they provided written informed consent prior to the study (including HD-tDCS stimulation).
   2. Ensure that all the necessary materials are available for device i....
