Abstract
Influence of the adequate vestibular stimulation by tilting about the longitudinal axis on the locomotor activity in hindlimb muscles evoked by electrical stimulation of the mesencephalic locomotor region was investigated in precollicularly decerebrated guinea pig. Rhythmic activity in extensors occurred during the horizontal position and ipsilateral tilt of the animal. Contralateral tilt was followed by a decrease in the extensor activity. Flexors revealed two periods of enhanced rhythmic activity; one during the ipsilateral tilt and another during the contralateral tilt. Mechanisms of the observed changes of the locomotor activity are discussed.
