Popis: This is a study of the relationship between cerebral events and visual attentional processes of schizophrenic patients by means of a spectral analysis method described in this paper. With recorded data it is possible to study the EEG, standard visual evoked potential, visual evoked potention with attention and visual ‘emitted’ potentials when stimuli were expected but absent. Compared with the sommation method and unitary analysis, the spectral analysis method appears very interesting, especially for the study of ‘emitted’ potentials because it avoids the subjectivity of operators and reduces the number of stimulations. The results show the interest of this simple reliable and effective method for the detection and objectivation of evoked activities with only very few (10) stimulations.
