[Electrical resistance of nerve tissue as a diagnostic criterion of pre-convulsive states].

For diagnosing pre-convulsive states use is made, as a rule, of electroencephalography. This method, however, not always gives satisfactory results. The authors present the results of experimental studies of the nervous tissue impedance in the period preceding the convulsive seizure induced in laboratory animals by electric stimulation of the limbic structures of the brain. The experiments showed that a few seconds before the generalization of the convulsive process one could note certain changes in the electric conductivity of the nervous tissue. These changes make it possible to take measures for preventing the seizure.

[Structure of hemodynamic responses in the central command to move].

Cardiac and vascular components of the hemodynamic response to "central command" to the skeletal muscles in immobilized decerebrated cats using an experimental model of "fictitious scratching" revealed that activation of the m. gastrocnemius increased blood pressure by 57 mm Hg, whereas cardiac output and blood flow in the common iliac artery changed insignificantly. The maximal increase of the blood flow in common iliac artery depended mainly on the stimulation of beta-adrenoreceptors by circulating catecholamines. The adaptive cardio-vascular responses during "central command" to skeletal muscles seem to depend mainly on the elevation of peripheral vascular resistance, there being no specific vasodilator influences on blood vessels of the muscles receiving the "central command".
