Cell differentiation within the brain of the fetus begins during the 16th week of gestation. During prenatal existence, growth occurs rapidly in the brainstem and in the primary motor and sensory areas. After birth there is rapid growth in the cerebellum and in the cerebral hemispheres, especially in the visual receptor areas of the occipital lobe. The auditory receptor areas of the temporal lobes mature somewhat later than the visual receptor areas, possibly explaining the relatively early visual maturity of the infant compared to later-developing auditory maturity. The association tracts devoted to speech and language will be relatively mature by late preschool, but some higher linguistic functioning areas will not fully mature until adulthood.

(c) At around 2 months of age, the motor cortex in the frontal lobe becomes more active. During this time, a child is gaining more control of volitional or voluntary motor behaviors, and many reflexive patterns are disappearing.
