[Ultrastructural features of cerebral synapses in schizophrenic patients].

The paper is concerned with ultrastructural traits of synapses in the frontal lobe, supraoptical nucleus of the hypothalamus and caudal nucleus of the brain in 12 schizophrenic patients and 8 normals (the period of autopsy was 4 hours following death). The results demonstrated 2 types of changes: 1) slightly expressed changes (a decrease of the extent of active zone contacts, changed forms in the synaptical vesicles); 2) extremely expressed or degenerative changes in the synapses (an appearance of fibrillar structures, glycogene granules, degeneration of synaptical endings of a dark type).
