E-meditation is a cutting edge, new method of meditation that combines neuromodulation via transcranial direct current stimulation (tDCS) with meditation. This new practice was pioneered by Dr. Bashar Badran of the Medical University of South Carolina, and quickly gained popularity for shortening the learning curve for meditation in beginner practitioners.
