<prompt> Human brain is more intelligent than monkeys brain due to:Larger brainIncreased convulationsIncreased brain area compared to body surface areaMore blood supply  <response>: A i.e. Larger brain The propoion of the various pas of the brain are similar in the brains of apes and human, but the human brain is largerQ, so the absolute size of the association area is greaterQ. Brain size: Human Chimpanzee MonkeyQ.Weight of Human brain1400 gm and Monkey brain 100gmAssociation AreasAssociation areas: are pa of six- layered neocoical mantle of gray matter that spreads over the lateral surfaces of cerebral hemisphere from concentric allocoical juxta coical rings around the hilum. The most prominent gross feature of the human brain is immense growth of three major association areasQ.i Frontal in front of premotor areaii Parietal temporal occipital - bw somatesthetic visual coex extending into posterior poion of temporal lobe.iii Temporal - from the lower poion of temporal lobe to limbic system. Speech other intellectual function are controlled by neocoex.The ratio bw brain weight and body weight is more impoant than size of the brain as three species have brains larger than humans the whale, elephant porpoiseThe right to left differentiation is seen in chimpanzee and human. In humans left brain Right brain
