Abstract

Investigating changes of a functional state of spinal motoneurons of the person under agency of afferent pulses from receptors of semicircular canals at шумовой to a load. Interacting between vestibular and acoustical sensory streams which reduce activity of motoneuron the inferior extremities of the person is revealed.
