title: [Somatotopic organization of the vestibulospinal tract in the toad].
abstract: The origin of the vestibulospinal projection in the toad has been investigated by using the method of the retrograde axonal transport of HRP injected at various levels of the spinal cord. The vestibulospinal projection, in this species, was found to be somatotopically organized, since neurons projecting to the cervical segments of the spinal cord were located within the rostromedial part of the ventral vestibular nucleus and those neurons projecting to the lumbosacral segments of the spinal cord were located within the caudolateral part of that nucleus. This pattern of organization of the vestibulospinal projection in amphibia is similar to that described in mammals and birds.
