Abstract
Systems and methods for determining brain health of a subject include or employ an electrical stimulator configured to apply a current to at least one pair of electrodes, and the electrodes are positioned on a skull of the subject to apply the current and to receive brain activity of the subject. The electrical stimulator is configured to apply a current having a waveform according to a Stochastic Gabor Function (SGF). A signal processor is configured to record the brain activity of the subject in the form of spectral electrical impedance data, and a computer system having non-transient computer readable media is programmed and configured to process the spectral electrical impedance data and indicate an impedance change within the brain of the subject.
