Our Brain

   What is the most complex computer?  Is it a Dell?  Is it an Apple?  No it's your brain!  It's weight is less than 3 pounds. It has 12 billion neurons.  It has 50 billion supporting glial cells. It controls body functions.  Your brain gives you the ability to think, remember, and imagine. 

   Your brain is divided in half by the longitudinal fissure.  The left hemisphere controls language, math, logic and the right side of your body.  The right hemisphere controls spatial abilities face recognition, visual imagery, music, and the left side of your body.

   Your brain is also divided into four lobes: the parietal lobe, the occipital lobe, the frontal lobe, and the temporal lobe.

   The parietal lobe plays important roles in forming sensory information from different senses.  The frontal lobe controls conscious thought; if there is damage it can result in mood changes. It also deals with planning, organizing, and problem solving.  It controls your personality, behavior, and emotions.  The occipital lobe controls sense of sight.

 The temporal lobe controls senses of smell and sound, as well as sorting new information.  It deals with our short term memory. 

     Learning about the brain is important because it can help doctors diagnose a problem in the brain.
