                                          The brain, the central organ of the
                                          human    nervous   system   that
                                          together  with  the  spinal  cord,
                                          forms  the  central  nervous  system
                                          of  the  brain.  Scientists  say  a
                                          second's  brain  work  equals  the
                                          work      of     millions     of
                                          supercomputers in a few hours.




                              The  brain  integrates  and  coordinates  the  information  it
                              receives from sensory organs and then processes, integrates
                              and coordinates, and ultimately decides on the instructions
                              sent to the rest of the body.


                                                   The brain consists of the brain, brainstem,
                                                   and cerebellum. The brain controls most of
                                                   the body's activities, such as processing,
                                                   integrating, and coordinating information
                                                   received from sensory organs, and makes
                                                   decisions by sending instructions to other
                                                   parts of the body.






                                                         The structure of the living brain is very soft and jelly-
                                                         like and the weight of an adult brain averages about 1/2
                                                         to 4.1 kg, i.e. approximately 2% of the total body
                                                         weight. Brain volume is about 1260 in men and about
                                                           .    1130 cubic centimeters in women


                                                  In each hemisphere of the brain, there are two
                                                  deep grooves, one lateral groove or silvin groove
                                                  and the other central groove or rosary groove,
                                                  which divides each hemisphere into four parts:
                                                  the forehead, the parietal, the occasional gag,
