title: [Dynamics of the dendrite and transcallosum potentials in the cerebral cortex in overheating].
abstract: Experiments were conducted on awake rabbits placed in a thermochamber at the temperature of 45 degrees C. The dendrite and the transcallosum potentials were examined in dynamics of the hyperthermia and after the restoration of the thermal homeostasis. The influence of high temperature was accompanied by an expressed inhibition of the amplitude of the dendrite potential, although to a lesser degree than of the transcallosum response. The data obtained could testify to a direct inhibitory thermal effect on the neuron elements of various layers of the cortex. Restoration of the cortical neuron function after the high degree hyperthermia occurred twenty-four hours after the body normothermia was reached.
