     1. (Anat.) 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.

           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.

From The Devil's Dictionary (1881-1906) :

  BRAIN, n. An apparatus with which we think what we think.  That which
  distinguishes the man who is content to _be_ something from the man
  who wishes to _do_ something.  A man of great wealth, or one who has
  been pitchforked into high station, has commonly such a headful of
  brain that his neighbors cannot keep their hats on.  In our
  civilization, and under our republican form of government, brain is so
  highly honored that it is rewarded by exemption from the cares of
  office.
