Paleoneurology
Paleoneurology
Paleoneurology (pronunciation: /ˌpeɪlioʊnʊˈrɒlədʒi/) is a branch of science that studies the evolution of the nervous system in prehistoric organisms, particularly the brain structure and function in extinct species.
Etymology
The term "paleoneurology" is derived from the Greek words palaios (meaning "old"), neuron (meaning "nerve"), and logia (meaning "study").
Related Terms
- Neuroanatomy: The study of the structure and organization of the nervous system.
- Neuroscience: The scientific study of the nervous system.
- Paleontology: The scientific study of the history of life on Earth through the examination of plant and animal fossils.
- Endocast: A cast or imprint of the inside of a skull, often used in paleoneurology to study the brain structure of extinct species.
Overview
Paleoneurology involves the study of fossil evidence, particularly endocasts, to understand the evolution of the brain and nervous system in extinct species. This field of study provides insights into the cognitive abilities and behaviors of extinct species, and contributes to our understanding of human evolution.
Paleoneurologists use various techniques to study the brain structure of extinct species, including computed tomography (CT) scans and Magnetic Resonance Imaging (MRI). These techniques allow scientists to create 3D models of endocasts, providing detailed information about the size, shape, and structure of the brain.
