The paper considers effects of the sodium salt of penicillin, on the bioelectric activity of the visual analyzer structures in rabbits. Penicillin was injected into the amygdale, and a focus was created in this structure. Modeling the epileptic focus in amygdale allows to detect the spread of excitation as in motor structures of the brain (clonic convulsions), and in various structures of the visual analyzer. A comparative analysis of the electrical activity of spe-cific (visual cortex, superior colliculus) and non-specific structures (suprachiasmatic nucleus of the hypothalamus) of the visual analyzer was performed in norm and after epileptic attacks. For this purpose, a coherent analysis of the electrical activity of the above-mentioned structures was per-formed in normal and after epileptic seizures. The experiments were carried out on rabbits. Registration and analysis of the electroencephalogram of various brain structures was performed by using the automated system "Brainsys". It is also established that there is a change in the coherent bonds between the structures of the visual analyzer after epileptic seizures. The coherence coefficient, except for the alpha range, increased in all structures compared with the background. The change in coherent bonds after epileptic seizures is explained by the activation of functional interactions between the structures of the central nervous system. The presence of high-amplitude theta and delta waves in the electroencephalogram indicates functional changes in the central nervous system. It is known that the visual analyzer has complex differentiated properties of plasticity. After epilepsy with the help of endogenous compensatory mechanisms it forms a new rela-tionship between the structures of the central nervous system.
