What are the mechanisms responsible for the development of Intelligence? In other words, why a person gets to be normal (IQ 100), while another is a genius (IQ 150). Is it Nature or Nurture?
Several studies have indicated that Intelligence is mainly inherited 2, as reported in an article published in the Journal of Neuroscience.
."...since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought. .....Genes appear to influence intelligence by determining how well nerve axons are encased in myelin — the fatty sheath of "insulation" that coats our axons and allows for fast signaling bursts in our brains. The thicker the myelin, the faster the nerve impulses".
In 2003 trial psychologist Jeremy Gray 6, then at Washington University in St. Louis, and his colleagues scanned the brains of 48 individuals using functional MRI, which detects neural activity by tracking the flow of oxygenated blood in brain tissue, while the subjects completed hard tasks that taxed working memory. The researchers saw higher levels of activity in prefrontal and parietal brain regions in the participants who had received high scores on an intelligence test, as compared with low scorers.
Ironically, many geniuses actually score poorly on standardised intelligence tests or perform very poorly at school – despite the fact that they have very high intellectual ability.......Aside from high intellectual ability, all geniuses also exhibit great creative intelligence.
I believe there is now enough evidence to bury once and for all the belief, held by some, we only utilize about 10% of our brain capacity while performing our usual tasks while leaving untapped the remaining 90%.
A corollary of this would be that, if we only knew how to put to work the idle part of the brain, we could increase dramatically our cognitive power. Indeed, Neuroscientists using imaging techniques such as fMRI, PET, and SPECT, have clearly shown the absence of any period of "quiescence" in brain activity, and that even during sleep, either REM or non-REM, there can be seen areas of activation such as the hippocampus, which suggests a role of sleep in memory consolidation.
Interestingly, neuroimaging studies of "Idiots Savants" have also revealed the presence of discrepancies between different areas of the brain. In particular, while the cortex was found to be thinner in the superior frontal gyrus, medial prefrontal cortex, and left middle temporal gyrus, a thicker cortex was present in bilateral portions of the superior parietal region.
Since intelligence is mainly inherited and congenital, people born to have an average (100) IQ won't certainly become geniuses in adulthood.
It has been shown furthermore, that physical as well as mental exercises, can improve cognitive performances of young adults and older people.
Although still much remains unknown about the inner workings of the human brain, progress made within the last half century bodes well for future discoveries and therapies.
Actually, one of the most promising fields of medical research being medical genetics and epigenetics, it comes easily to mind the possibility that one day these techniques will be in common use not only to treat neurological diseases such as Alzheimer, Parkinson, Dementia, ADHD, and Autism, but also to enhance permanently the intelligence of normal people.
