[Changes in the locomotor activity of muscles of the forelimb of the guinea pig during translation of the animal with respect to the longitudinal axis].
Changes in spontaneous locomotor activity of forelimb muscles evoked by adequate stimulation of vestibular system were investigated in decerebrated guinea pigs. Extensor activity in stance phase increased and flexor activity in swing phase decreased during a tilt ipsilateral to the prepared limb, opposite changes were observed during the contralateral tilt. The alternation pattern of antagonist muscle activity was not changed. Revealed changes in the locomotor activity were more pronounced during cyclic shifts than during fixed tilts.
