High-Resolution Electrical Head Models for Dense Array Neuromodulation

EGI's new Geodesic Transcranial Electrical Neuromodulation (GTEN) technology integrates EGI's core GES 400 dEEG platform and its proprietary head modeling technology to create a precise method for tDCS/tACS/tPCS neuromodulation tailored for the individual.

In this symposium, a bounded electrical impedance tomography (bEIT) approach will be presented for individually specific calibration of high-resolution electrical head models. bEIT is used to estimate the most important electrically resistive tissue (the skull) of the head. The resulting calibrated, anatomically accurate, electrical head model is then used for EEG source estimation and transcranial electrical stimulation (TES) planning. Based on EEG source estimation, targets are defined for TES and simultaneously recorded EEG can be examined to assess the brain’s response to the stimulation.
