[Comparative analysis of the dimensions of vestibulo-spinal neurons in the guinea pig].
The comparative analysis of dimensions of horseradish peroxidase labelled vestibulo-spinal neurons and neutral red stained neurons of undifferentiated areas of the vestibular nuclei have been performed in guinea pig. The undifferentiated areas of the vestibular nuclei consisted of small, medium, large and giant cells. A decrease in the relative numbers of small- and medium-diameter neurons and an increase in the relative numbers of large and giant neurons have been observed along the caudo-rostral axis of the vestibular complex. The vestibulo-spinal populations included neurons of medium, large and giant dimensions. The numerical superiority of large and giant neurons have been found. The even distribution of the vestibulo-spinal neurons of different diameters have been revealed along the longitudinal axis of the brainstem.
