The goal of the present study was to investigate the local synchronized neuronal activity in the cat visual cortex and the role of different classes of neurons in neural synchrony. Four classes of neurons were identified on the basis of electrophysiological properties of extracellular recorded cells: RS, FS, IB and FRB. It was revealed that neurons with short spikes and FRB type of activity were first engaged in synchronization.

The modeling is based on a biologically inspired computational model that simulates the behavior of bilaterally located populations of binaural auditory neurons. To assess neural model responses in terms of psychophysical data, a special method is designed.

Studies of the antioxidant status showed an important role of lipid peroxidation metabolites in the formation of endogenous intoxication during the early postoperative period, manifesting, among other things, by decreased albumin transporting function.

A reduction of LHB and disorders of lipid metabolism were observed before surgery. After surgery LHB was still reduced on days 1-3.

Multiple-modality intensive care included, besides routine therapy, local abdominal hypothermia, UV irradiation of autoblood (UVIAB), and, if indicated, hyperbaric oxygenation (HBO) and hemoperfusion. In addition to clinical tests, immunobiochemical monitoring of medium-molecular peptide fractions MM1 and MM2 and index of their distribution, as well as of circulating immune complexes CIC1 and CIC2 and the levels of immunoglobulins IgA, IgM, and IgG were the criteria for assessing the severity of intoxication and efficacy of intensive care and for predicting the course and outcome of the disease.
