Altered electrophysiological pattern of target detection in schizophrenia in the Continuous Attention Test
Acta Neurobiologiae Experimentalis
Visual evoked potentials were examined in 50 male schizophrenic patients and 50 age-matched healthy male volunteers during performance of the Continuous Attention Test (CAT). In the patients emerged an evident deterioration of attentional processes: much higher index of errors and longer reaction time than in the healthy subjects. On the other hand, in patients the following alterations in evoked potentials were found: (1) in the non-target condition lower amplitudes of components: left-sidedpmid:9803014 fatcat:uz3qsmzpu5h7vletlxv4gkpzby
