BRAIN: its organization 1)5)
← Back
The main parts of the brain are the following (for locations see fig.)
The definitions are from J. ECCLES (J.E.)(1977), or from the American Heritage Dictionary (AHD), (1978 ed.)
- Archicortex: the ancient part of the cerebral cortex; it includes the hippocampus (J.E. p. 234)
- Cerebellum: the brain structure responsible for regulation and coordination of complex voluntary movements (AHD, p. 219)
- Cerebral cortex: the extensive outer layer of gray tissue of the cerebral hemispheres, largely responsable for higher nervous functions
- Cerebro-cerebellar pathways: the complex pathways linking the cerebral cortex and the cerebellum in both directions (J.E. p. 234)
- Cerebrum: the main structure of the brain occupying most of the cranial cavity and divided into two cerebral hemisphers (AHD, p. 219)
- Corpus callosum: the tract of nerve fibers connecting the cerebral hemispheres (J.E. p. 235)
- Hippocampus: one of two ridges along each lateral ventricle of the brain (AHD, p. 624)
- Hypothalamus: a deep laying part of the cerebral cortex, concerned in visceral control , f. ex. in relation to temperature, salt, water, food, endocrines, and mood (J.E. p. 238)
- Medulla oblongata: the nervous tissue at the bottom of the brain that controls respiration, circulation and certain other bodily functions (AHD, p. 816)
- Neo-cortex: the most recently developed part of the cerebral cortex, composing the cerebral hemispheres (J .E., p. 236) The neo-cortex includes an enormous array of interconnected neurons
- Thalamus: the massive collection of nerve cells deep to the cerebral cortex, in part concerned with transmission of cutaneous sense to the cerebrum.
- Ventricle: a small anatomical cavity in the brain (AHD, p.1421)
A part of the thalamus (called ventrolateral) is specially concerned by the transmission from the cerebrum to the cerebellum (J.E. p. 243)
This is of course a very simplified and sketchy description of the brain's structures.
For much better information see f. ex. J. ECCLES (1978), J.Z. YOUNG (1978) here also used, or some more recent work, as for ex. R. CARTER (1998)
