[Functional state of the frontal cortex and ventromedial hypothalamus during physical overexertion and experimental neurosis in the rabbit].
A change of excitability, pO2 and local cortical blood flow under a long-term maximum physical load and in conditions of experimental neurosis, was investigated in rabbits with electrodes implanted in the frontal cortex and ventromedial hypothalamus. It was found that functional activity of these structures under physical orverstrain rises as the blood flow and pO2 increase, and the excitability also increases. In experimental neurosis, a discoordination in functioning of the cortex and hypothalamus is observed. Relative stabilization of the functional state of tested structures, observed during physical overstrain, is absent in conditions of experimental neurosis.
