Abstract

1. The histological organization of the rat dorsal lateral geniculate nucleus (Cgld) has been analysed in Nissl-preparations following vessel injection with india ink. 2. The findings have been collected by means of a non-automatically visual scanning method. Every point is defined by 3 coordinates. 3. Different parameters have been collected in every point: the number of the 5 structural elements of the nervous tissue (neurons, fragments of capillaries, nuclei of astrocytes, oligodendrocytes and microglia) and the hit points per structural element. 4. In addition the differentiation of about 15500 neurons in relay neurons and interneurons has been carried out. The ratio of the 2 types of neurons is about 14:1. 5. The collected values have been statistically analysed by correlation, regression and discriminatory analyses. 6. The results relate to the correlation between the structural elements and the rostrocaudal, lateromedial and ventrodorsal directions as well as the structural elements with another. 7. At 5 levels the Cgld has been mapped on the basis of neuron size, neuron density, capillary density, density of the 3 types of glial nuclei and the relative number of hit points per structural element. 8. In the Cgld we disti...Continue Reading

Astrocytes & Neurodegeneration

Astrocytes are important for the health and function of the central nervous system. When these cells stop functioning properly, either through gain of function or loss of homeostatic controls, neurodegenerative diseases can occur. Here is the latest research on astrocytes and neurodegeneration.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
