FRIDAY, Feb. 26 (HealthDay News) -- It's not a particular brain region that makes someone smart or not smart.
Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume.
Instead, new research shows, it's the connections between very specific areas of the brain that determine intelligence and often, by extension, how well someone does in life.
"General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons," said Jan Glascher, lead author of a paper appearing in this week's issue of the Proceedings of the National Academy of Sciences. "General intelligence relies on the connection between the frontal and the parietal [situated behind the frontal] parts of the brain." MORE HERE
I have always pondered as to what makes a human being intelligent (or the lack thereof)? This article reveals a bit of the reason why some brains excel in intelligence while others are inferior. IQ may simply be a matter of brain [sic]liaisons (lesions - thanks to Ezekial) (the injury or damage to tissue within the brain as in Alzheimer’s disease). So the next time you hear someone talking gibberish, especially if he/she is seeking a position of power, try to imagine what is causing that gibberish... there may be a brain "lesion" lurking behind that wide forehead. Maybe that imagery will be enough to convince us to vote for the smart guy. Now if we could only solve the riddle of why one man/woman’s gibberish seems like rationale and eloquence to some while another man/woman’s rationale and eloquence seems like gibberish to others. Solve that and we will all live together harmoniously. (Believe that and I’ve got some swampland to sell you.)
