BRAIN
Brain, n. Etym: [OE. brain, brein, AS. bragen, brægen; akin to LG.
brägen, bregen, D. brein, and perh. to Gr. 95.]
1. (Anat.)
Definition: The whitish mass of soft matter (the center of the nervous
system, and the seat of consciousness and volition) which is inclosed
in the cartilaginous or bony cranium of vertebrate animals. It is
simply the anterior termination of the spinal cord, and is developed
from three embryonic vesicles, whose cavities are connected with the
central canal of the cord; the cavities of the vesicles become the
central cavities, or ventricles, and the walls thicken unequally and
become the three segments, the fore-, mid-, and hind-brain.
Note: In the brain of man the cerebral lobes, or largest part of the
forebrain, are enormously developed so as to overhang the cerebellum,
the great lobe of the hindbrain, and completely cover the lobes of
the midbrain. The surface of the cerebrum is divided into irregular
ridges, or convolutions, separated by grooves (the so-called fissures
and sulci), and the two hemispheres are connected at the bottom of
the longitudinal fissure by a great transverse band of nervous
matter, the corpus callosum, while the two halves of the cerebellum
are connected on the under side of the brain by the bridge, or pons
Varolii.
2. (Zoöl.)
Definition: The anterior or cephalic ganglion in insects and other
invertebrates.
3. The organ or seat of intellect; hence, the understanding. " My
brain is too dull." Sir W. Scott.
Note: In this sense, often used in the plural.
4. The affections; fancy; imagination. [R.] Shak. To have on the
brain, to have constantly in one's thoughts, as a sort of monomania.
[Low] Brain box or case, the bony on cartilaginous case inclosing the
brain.
– Brain coral, Brain stone coral (Zoöl), a massive reef-building
coral having the surface covered by ridges separated by furrows so as
to resemble somewhat the surface of the brain, esp. such corals of
the genera Mæandrina and Diploria.
– Brain fag (Med.), brain weariness. See Cerebropathy.
– Brain fever (Med.), fever in which the brain is specially
affected; any acute cerebral affection attended by fever.
– Brain sand, calcareous matter found in the pineal gland.
Brain, v. t. [imp. & p. p. Brained; p. pr. & vb. n. Braining.]
1. To dash out the brains of; to kill by beating out the brains.
Hence, Fig.: To destroy; to put an end to; to defeat.
There thou mayst brain him. Shak.
It was the swift celerity of the death . . . That brained my purpose.
Shak.
