ADDITIONAL INFORMATION ABOUT THE CENTRAL AUDITORY-DISCRIMINATION ABILITY OF APHASICS

The differences of sensorimotor (global) and motor aphasias using elec trophysiological recordings of cortical regions after different acoust ic stimuli are described. For appreciation of the auditory perception ability of patients with aphasia slow auditory evoked potentials were recorded from temporal regions, after stimulation with tone, white noi se, and word stimuli. For the global aphasia group (with speech compre hension lesion) normal cortical complexes were not recorded. These res ults could contribute to the discrimination of the two main types of a phasia (global and motor).
