# Neuronal diversity in the caudate nucleus: A comparative study between camel and human brains

## TL;DR

This study compares the types of neurons in the caudate nucleus of camels and humans, revealing structural differences that may reflect evolutionary adaptations.

## Contribution

The study identifies and compares three neuron types in camel and human caudate nuclei, highlighting interspecies structural diversity.

## Key findings

- Three neuron types (Type I, II, III) with subtypes were identified in both camel and human caudate nuclei.
- Camels and humans showed significant differences in soma size, dendritic morphology, and spine distribution.
- The findings provide insights into evolutionary adaptations of neural structures in the caudate nucleus.

## Abstract

Caudate nucleus (CN) neurons in camels and humans were examined using modified Golgi impregnation methods. Neurons were classified based on soma morphology, dendritic characteristics, and spine distribution. Three primary neuron types were identified in both species: rich‐spiny (Type I), sparsely‐spiny (Type II), and aspiny (Type III), each comprising subtypes with specific features. Comparative analysis revealed significant differences in soma size, dendritic morphology, and spine distribution between camels and humans. The study contributes to our understanding of structural diversity in CN neurons and provides insights into evolutionary neural adaptations.
