Abstract

Many researchers studied the brain as the basis for considering intelligence and measuring it. Many aspects of brain anatomy and physiology have been suggested as possibly related to intelligence. The branching of neurons in the cerebral cortex, the metabolism of cerebral glucose, the speed of transmission of nerve signals are some of the factors of Physiology that have been found to be related to intelligence. Regard to the genetic origin of intelligence, research projects results mainly prove that heredity has a stronger effect in relation to the environment on mental differences. They focus on a variety of cases of twins, such as monozygotic twins and dizygotic twins, biological and step brothers, each of whom was raised together or separately from infancy or later in life. Finally, in recent years, some studies have investigated alcohol exposure during pregnancy as a factor in the subsequent decline in children's intelligence, while others disprove the method of in vitro fertilization and in particular ICSI since the results almost ruled out any delay in the mental development of the child.
