A of the present day study graphically reveals that the brain's center of reasoning and enigma solving is among the last to mature, according to a May 17 2004 stranges release from the National Institutes of Health. A magnetic resonance imaging (MRI) cogitation of normal brain development in individuals aged four to 21 years, displays that "higher-order" brain centers do not to the full develop until early adulthood.

Researchers used MRI to scan 13 healthy children and teenagers each two years for 10 years. Using an intricate establish of brain anatomical landmarks, they visualized the reflux and flow of gray matter in maps that form a time-lapse "movie" showing brain maturation from ages five to 20

The movie point outs gray matter diminishing in a back-to-front wave, probably reflecting the purging of unused neuronal connections during the teen years. Cortex areas tan be seen maturing at ages at which relevant cognitive and functional developmental milestones occur

The research also found that the last front and back of the brain--those controlling the principally basic functions, such as movement--are the first areas to mature. The parietal lobes--areas involved in spatial orientation--mature nearest and the prefrontal cortex, which performs more advanced functions, matures last.
