Cybernetics and consciousness.

This paper is a review of hypotheses of consciousness which arose from application of the theory of information and regulation and the cybernetic theory of mathematical machines in medicine. The author presents these hypotheses on the examples of his own works.

[Numeric description of circadian rhythm of TSH in patients with cold tumors of the thyroid gland before and after surgery].

Circadian rhythm of TSH was analyzed in patients with cold tumors of the thyroid before and after surgical removal of the tumors and in control subjects. By using special computer program BIOR based on harmonic and regression analysis, designed for verifying and comparing various biorhythms, significant differences were found between TSH biorhythms in patients with cold thyroid tumors before and after the operation.

[Changes in synaptic potentials and axonal delays as factors causing epileptic instability of neuronal networks].

Synaptic weights, axonal delays and excitability thresholds are three basic parameters influencing the function of neuronal network as a dynamic system. Changes of the general level of the signal flow, without changes in relation between excitatory and inhibitory connections can cause pathologic oscillations in the network. The conductivity in neuronal nets depends on electrochemical processes and may be influenced by the pH-status, ion concentrations, among other parameters.
