1. A bi-directional method of carrying out electrophysiological data recording and analysis with manual or automated delivery of transcranial current stimulation, comprising the steps of: via at least one electrode, conducting a non-invasive measurement of electrical currents within a brain of a person; determining functional abnormality in said person based on said conducting while providing directed sensory stimuli to said person; sending a non-invasive brain stimulation using low threshold transcranial magnetic stimulation to the brain of the person.
