The brain is the greatest single system in our universe..

Review of information does not hurt you as information too can change. The brain weighs 2-4 pounds, consists of 60 % fat and uses 25 % of your blood every time your heart beats. It is divided into 2 hemispheres -a left one and a right one. The left hemisphere is responsible for language details, and analyzing situations. The right side deals with recognizing faces, spatial orientation and sounds.
The brain is responsible for thought, emotion, and behaviour. The human brain and the animal brain are the same type of brain as they both are able to generate new brain cells. More tomorrow on sections of the brain.
