  Brain  \Brain\,  n.  [OE.  brain,  brein,  AS  bragen,  br[ae]gen;  akin 
  to  LG  br["a]gen,  bregen,  D.  brein,  and  perh.  to  Gr  ?,  the

  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. 
 
  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

  {M[ae]andrina}  and  {Diploria}.
