Description
Abstract
To study the effects of senescence on the
vestibular nuclear complex twenty brainstems from male
golden hamsters between 3 and 27 months-old were used
and the possible variations in the number of neurons,
neuronal morphology and nuclear volume were studied.
The neuron profiles were drawn with a camera lucida
and Abercrombie's method was used to estimate the total
number of neurons. The test of Kolmogorov-Smirnov
with the correction of Lilliefors was used to evaluate the
fit of our data to a normal distribution and a regression
analysis was done to decide if the variation of our data
with age was statistically significant. The results of the
present study are relevant only for male animals and the
effect of senescence could be different in female
vestibular nuclear complex. Aging affects the volume of
the superior and lateral vestibular nuclei, as well as the
nuclear neuronal diameter of the medial vestibular
nucleus, but no significant neuronal loss has been
appreciated in vestibular nuclear complex related with
age. During the aging process we have observed that the
distribution of neurons within the vestibular nuclei of the
golden hamster does not show important changes and
most of their morphometric parameters do not vary
significantly.
