title: [Correlation between the theta rhythm energy characteristics in the cortex and motor reactions in rabbits].
abstract: The effect of the theta-rhythm energy on the transmission of excitation from the visual analyser to the motor one was studied in an automatized controlled experiment. It has been found that the probability of motor reaction to a photic stimulus correlates with definite energetic characteristics of theta-rhythm in the sensorimotor and visual cortical areas. Most favourable for the appearance of rabbit's motor response to photic stimulation is the similarity of mean theta-rhythm values in different cortical areas. It is assumed that recurrent inhibition in neuronal cortical systems delimits the excitation irradiation in the cortex in the case of high theta-rhythm amplitudes.
