Brain is an organ Consisting of Neurons, and Blood vessels it is responsible for thinking, judging and motoric abilities… The best way to improve it is USING IT… by reading Science Books, Playing Complex Puzles… and thinking in general… and try to stay avay from: Drugs, Tobaccos and Alcohol, or at least take it in reasonable doses and try not to be an addict of any kind to anything… Your Soul or Psyche (Way of Thinking and Perceiving the World) is IN the BRAIN, and it depends on functionality of your Brain, so if you damage your brain or blood vessels… you get the picture… Best of Luck and THINK POSITIVE… did this help you?

he brain is the center of the nervous system in all vertebrate and most invertebrate animals—only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have one, even if diffuse neural tissue is present. It is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain of a vertebrate is the most complex organ of its body. In a typical human the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons,[1] each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.
