The CNV was studied in a group of 14 human subjects with traumatic brain injuries followed by a protracted coma. Before the CNV recording, all the patients were subjected to Wechsler-Bellevue Intelligence Scale and to Benton's Visual Retention Test. The findings of the recording were compared with those obtained from 80 normal subjects and from 20 subjects with different cerebral diseases. A statistically significant decrease was observed in the CNV area in the group of subjects with traumatic lesions. No correlation could be found between CNV parameters and the results of the mental tests. In 4 of the subjects who presented the highest percentage of errors at Benton's test, a large post-imperative negative variation was observed. The studies were discussed on the basis of the latest physio-pathological views concerning the CNV studies.
