Visual evoked responses and their dispersion pattern in neurotic patients

The AVER (averaged visual evoked responses) and the DP (a pattern of dispersion resulting from the variability of each time point locked to the stimulus onset: D = F [T]) were studied in neurotics in comparison with controls. In neurotics without depression and/or anxiety the AVERs were normal and the DPs showed a shortening of the second period; in neurotics with depression and/or anxiety the AVER'S were also normal but the second period of the DPs disappeared.
