Based on the data available in the literature and his own findings, the author presents a concept of the spatial-temporary organization of biological systems. Experimental evidence is provided for this concept with emphasis on its theoretical and medical values. A role of spatial and temporary organization in the activity of the biological system is shown separately. It is emphasized that the spatial-temporary organization of biological system is not the sum of properties of components of its spatial and temporary organizations and has its own features. The author proposed to single out a section of theoretical biology dealing with the study of the spatial-temporary organization of biological systems and to call it chronotopobiology.

The complex research, including clinical scales (FIM, Mayo-Portland) and data on stabilography and electroencephalography (EEG) studies, was conducted in 10 patients with posttraumatic Korsakov's syndrome (KS) before and after the rehabilitation course using stabilo-training (ST) with feedback (7-12 sessions). A control group consisted of 18 healthy people. In patients with KS, more severe cognitive (memory) disorders were noted before ST that was correlated with the maximal reduction of coherence in all frequency bands in frontal and parietal-occipital areas as well as in the long diagonal pairs between the left frontal and the right parietal-occipital areas which was most distinct for the alpha-band.

The aim of the study was a comparative analysis of spatial-temporary organization of P300 acoustic evoked potential (AEP) in patients with local lesions of the brain stem, frontal and temporal structures in the situations of "passive" listening to sounds and their active recognition (a count). Specific changes of P300 parameters were distinguished in each group. The peak-temporary P300 parameters--latency increase, decrease of amplitude and tendency to the decrease of half-cycle--were similarly changed, irrespective of brain damage topography.

To reveal physiological correlates of the schizophrenic thinking peculiarities associated with impaired mechanisms of information selection, spatial synchronization of the cortical biopotentials was studied in 10 healthy probands and 9 patients with continuously progressing schizophrenia. Both the healthy probands and the patients were asked to solve problems of comparing notions in situations where standard or non-standard criteria for the solution could be chosen. The bioelectrical activity was recorded at 48 cortical sites with subsequent estimation of the cross-correlation interconnections between the EEGs.
