[Sensitivity of "silent" and spontaneously active neurons of the cat cerebral cortex to anoxia].

Using the complex methodical approach on the basis of in vivo microscopy of the cat motor cortex preparation the common principle of reaction of both the "silent" and the spontaneously active pyramidal neurons was revealed: their "seizure discharges" activation in hypoxia only occurred in a certain rather obvious disturbance of the intracellular redox-systems condition. At the initial stages of the firing changes in the spontaneously active neurons, no noticeable increase in their redox-systems restoration was observed.
