[Spatial distribution of correlative associations in the electrical activity of schizophrenic patients]. / Prostranstvennoe raspredelenie korreliatsionnykh sviazei élektricheskoi aktivnosti u bol'nykh shizofreniei.

The paper deals with the space distribution of correlational contacts of electric activity in 5 areas of the cortical brain in producing non-signal photo stimula and in conditional trace reflexes with a preliminary verbal instruction. Such studies were convened in schizophrenic patients and in normals. The author assessed the general and regional coefficient of cross-correlations in certain time periods prior to and following production of photo signals. More distinct differences between normals and schizophrenic patients (especially with juvenile malignant schizophrenia) were seen after an instruction and conditional signals. In patients the signal activity was not accompanied by a formation of a system of functional contacts which may be seen in normals, and which possibly may be the basis in the functioning of a conditional reflex.
