Morphometric parameters of some hypothalamic nuclei: age-related changes.
The morphometric analysis of some hypothalamic nuclei was performed on 20 brains of subjects of both sexes aged from 29 to 79 years. They were divided into two groups: below and above the age of 60. Supraoptic (SON), lateral tuberal (LTN) and lateral mammillary (LMN) nuclei were investigated. In the group of aged subjects a decrease in cross-section area of neuron nuclei was observed in all investigated structures, expressed most in the LTN. A considerable increase in the neuron density with age was found in the LTN. The size of neuron cell bodies and the number of neurons did not change significantly with age in any of the investigated nuclei.
