Morphological characteristics of different types of neurons in the ventrooralis anterior, ventrooralis internus, and ventrooralis posterior nuclei in the human thalamus
Abstract
1. Golgi-Kopsch preparations of the oral ventral nuclei of human thalamus were analyzed in an attempt to classify the neuronal types. 2. Three types of neurons are described for the first time in humans. Type I neurons are large or medium in size and bear dendrites with protrusions, spines, and short hair-like appendages. Some have a radiate dendritic arbor and others have dendrites grouped in tufts. The dendritic trees of these neurons are dense. 3. Type II neurons are medium or small in size with less dense dendritic trees. These cells have somatic as well as dendritic appendages of different forms. 4. Relatively rare is a type of very small neurons, type III, with few and sparsely branching dendrites.
