Dataset of concurrent EEG, ECG, and behavior with multiple doses of transcranial electrical stimulation

What is this?

The GX Dataset is a dataset of combined tES, EEG, physiological, and behavioral signals from human subjects.

All aspects of this project are fully open source. If you are having access issues please contact us below.

Description

A dataset combining high-density electroencephalography (EEG) with physiological and continuous behavioral metrics during transcranial electrical stimulation (tES; including tDCS and tACS). Data includes within subject application of nine High-Definition tES (HD-tES) types targeted three brain regions (frontal, motor, parietal) with three waveforms (DC, 5Hz, 30Hz), with more than 783 total stimulation trials over 62 sessions with EEG, physiological (ECG or EKG, EOG), and continuous behavioral vigilance/alertness metrics (CTT task).
