Noninvasive Brain Stimulation on Memory in Individuals With Mild Cognitive Impairment and History of Brain Injury

This wireless device delivers a very low electrical current to focused regions on the scalp in order to modulate underlying brain circuits to promote neuroplasticity. The device will be fitted onto a neoprene EEG cap, with 1 anode electrode placed and surrounded by 4 cathode electrodes in a ring pattern. Electrical stimulation will be applied using a constant voltage cortical stimulator (Model D185, Digitimer Ltd, UK, maximal output 1000 V/1.5 A) with single square-wave 50-μs pulses (0.1 A/μs rise time).
