ABSTRACT
A dynamical model of the neuronal network based on the principles of spatial-temporal organization of information processing was constructed. The additivity law for the formation of input connection factors in this model provides its versatility for a variety of logical functions. The model takes into account real properties of the systemic organization of brain neurones.

192 patients, aged 33 to 67 years, predominantly after abdominal and small pelvic surgery have been examined. Non-conventional techniques of analgesia were used in most of patients: central electroanalgesia, transcutaneous peripheral and paravertebral electroanalgesia, corporal and auricular acupuncture. To ensure postoperative pain relief various types of electrical stimulation were applied using home-made devices, The efficacy of non-conventional anesthesia techniques in the postoperative period has been confirmed.

The kinesthetic and acoustic analyzers were investigated in 62 enuretic and 50 healthy children. In patients, the sensitivity thresholds of the analyzers were substantially increased. The fall in function of the sensory sphere is a major pathogenetic factor of the disease.

As many as 62 children aged 9 to 14 years with enuresis underwent electroencephalographic examinations. Assay of alpha-activity and study of its correlation dependence made it possible to reveal a decrease in excitability of the projection zones of the cortex of the large hemispheres and weakening of functional conjugation between them. After performing a complex of treatment measures including actions on the acupuncture points, intake of nootropic agents, vitamins a tendency was noted towards normalization of the status of the sensory and integrative brain structures. The EEG manifestations of enuresis may be determined by functional changes in the level of excitability of the cortex of the large hemispheres and derangements of intercentral relations.

A study was made of the time-course of changes in function of kinesthetic and acoustic sensitivity in children (n-62) aged 9 to 14 years suffering from enuresis undergoing acupuncture based on cauterization of acupuncture points with 25% silver nitrate. The patients with enuresis manifested normalization of the sensitivity of the analyzers under study. The clinical results of enuresis treatment depend on the degree of correction of the alterations in function of the analyzers. The measurement of the threshold sensitivity of the sensory systems can be used for the control of the efficacy of the therapeutic measures taken in patients suffering from enuresis.

In chronic experiments on cats interrelations were studied between impulse activity of neurones of various auditory cortical zones and associative area under the action of defensive, alimentary or differential acoustic signals. It was found that shifts of the impulse activity of neurones in the studied cortical zones and correlation dependence between them appearing in the given conditions, were of a selective character and were connected with signal meaning of acoustic signals. Neurophysiological mechanisms are discussed of the revealed reorganization of the composition of functional relations of neurones of the cortical representation of the conditioned stimulus analyzer.

In chronic experiments on cats, reorganization of initial interrelations between alpha-activity of higher parts of the auditory analyzer during acoustic stimulation was of a selective character and depended on motivational properties of the elicited excitation. A conditioned acoustic signal of alimentary situation, greatly intensified the functional conjugation of the majority of studied auditory projections and a number of non-specific structures, while in a defence situation there was a considerable reduction of correlative dependence between compared characteristics of the auditory centers state and a change in the hierarchy of their functional interrelations.

The interrelationships of stimulation thresholds in the auditory cortical areas AI, AII, and Ep were studied in chronic experiments on cats. The linear correlation existed between the fluctuations of excitation levels of the auditory areas. The correlation coefficients could be changed by sound stimulation. Administration of amphetamine and aminazine as well as anodal polarization of the midbrain reticular formation revealed participation of the latter in establishing of the above interrelationships.
