General principles of neuron organization in the human dorsal thalamus nuclei

Abstract

In the human dorsal thalamus nuclei (VA, VL, AV, AM, AD, andMD), neurons were studied using Goldgi staining method. Themethod allowed identifying different species of long-axon neurons(type I): densely branched bushy neurons, bushy spine neurons,large and gigantic bushy neurons, tree-like (arborescent) neurons,brush-like neurons, double-tufted neurons, and intermediary (orcombined) neurons. Species of sparsely branched neurons werealso identified: short-dendritic neurons and reticular neurons. TypeII neurons short-axon neurons (interneurons) were presentedby smooth-dendritic, shaggy-dendritic and long-dendritic neurons.A classification of the nerve cells of the dorsal thalamic nucleiis proposed, and some principal features of their internal organizationare established.
