CNVs were studied in a group of 27 subjects with traumatic head injuries followed by protracted coma. Before CNV recording, all patients were subjected to Wechsler-Bellevue Intelligence Scale and to Benton's visual retention test. The findings were compared with those obtained from 80 normal subjects. A statistically significant decrease was observed in the CNV area in the group with traumatic lesions. No correlation could be found between CNV parameters and the results of the mental tests. In 7 of the subjects who presented the highest percentage of errors in Benton's test, a large post-imperative negative variation was observed.
对一组27名创伤性颅脑损伤后长期昏迷的受试者进行了CNV研究。在记录CNV之前，所有患者都接受了韦克斯勒-贝尔维尤智力量表和本顿视觉保持测试。将研究结果与80名正常受试者的结果进行比较。在有创伤性病变的组中观察到CNV面积有统计学意义的减少。未发现CNV参数与心理测试结果之间存在相关性。在本顿测试中错误率最高的7名受试者中，观察到较大的指令后负变化。
