As professor of pediatrics, neurology and radiology at the Wayne State University School of Medicine, and director of the Positron Emission Tomography Center at Children's Hospital of Michigan, he and his colleagues have observed patterns of complex brain maturation, which shape a child's learning capacity and behavior at very precise times. Furthermore, a direct link has been drawn between the focal area of energy concentration and the development of certain behaviors. As the child matures and phylogenetically newer regions of the brain become functionally active, the child achieves greater behavioral complexity. By three months of age, glucose consumption has risen in the parietal and temporal cortex, corresponding to increased coordination and the child's more fluid and intentional reaching movements. By eight months, much of the frontal cortex is activated, which coincides with a child's higher cognitive function and his ability to be more aware of his surroundings.
Children undergo a complex process of brain development very early in life.
Much of this is a natural biological progression, but Mother Nature didn't think it was advisable for genetic composition alone to dictate brain wiring. At some point, very early in childhood, the automatic responses subside and the rest is left up to the parents or caretakers. That's when the fun begins. Peering into the childhood brain A child's brain begins as a chaotic pool of unconnected neurons waiting to be stimulated, directed and wired in some logical pattern. This complex wiring creates an excessive number of connections, causing the brain to rapidly overdevelop between the ages of two and 10.
