The remediative effect of galvanic vestibular stimulation (GVS) was investigated in a patient who, following right hemisphere damage, is profoundly unable to recognize faces. We administered a two-alternative forced choice match-to-sample task in which the patient had to choose which of two faces matched a sample face presented directly above, while bipolar, transcutaneous Current was applied to the left and right Vestibular nerves at a level below the patient's sensory threshold. Performance improved beyond the chance-level observed prestimulation. and relied on reversing the electrode polarity across two separate blocks of trials. such that each mastoid receiv...
