New research has demonstrated that small variations in the genetic code of the HMGA2 gene may be impacting your brain size and IQ. According to study leader Paul Thompson, these variations “can tilt the scales in favour of a higher intelligence.” The researchers acknowledged that genetics, education, and environmental factors all likely play a role in determining our intelligence and that, according to Thompson, “most other ways we know of improving brain function more than outweigh this gene.”
Although the effect of this gene is small, the researchers feel that the gene variations may help our brains resist cognitive decline as we age. Interestingly, they found that every “T” in place of a “C” correlated with a 0.6% reduction in brain size, which they say is equal to more than a year’s worth of brain loss due to normal ageing processes. Guess this means that the next time you worry about the size of your head remember that it may mean you have a bigger brain and are potentially smarter than your smaller headed friends.
