Sensory stimulation during sleep. Observations on the EEG responses to auditory stimulation during sleep in patients with brain pathology (Preliminary report).
1. Potentials evoked by auditory stimulation during sleep were studied on a group of patients with unilateral brain damage resulting from external trauma cerebral vascular accident and tumor. 2. In a normal control group the response patterns from homologous areas in the two hemispheres were almost identical (except for the temporal leads). 3. In contrast with this, responses from damaged areas show distinct distortion of the pattern. 4. Records of typical cases are presented.
