Human Brain Nuclei Low-poly 3D model

Human beings describe in neuroanatomy a cluster called a nucleus (plural form: nuclei) as being found within the central nervous system, situated deeply within the cerebral hemispheres and brainstem. The neurons housed inside one nucleus usually possess roughly similar connections and functions together. Nuclei link up to other nuclei through tracts, these being bundles of axons extending from the cell bodies themselves. One type of organization for nerve cells is a nucleus - layered structures like the cerebral cortex or cerebellar cortex make up another most common form. Anatomical sections reveal a nucleus as a grey area of matter, usually bordering white matter on all sides. Hundreds of distinctive nuclei can be found within vertebrate brains, ranging greatly in size and shape. A nucleus may possess its own internal structure as well, with different types of neurons grouped together in clumps or layers in complex patterns.\n\nThe term "nucleus" is sometimes used rather loosely, to describe any distinguishable group of neurons present even if spread over a wide area. For example, the reticular nucleus within the thalamus appears as an identifiable layer of inhibitory neurons that completely surround this region itself.
