An interesting statement was made by experts from new Mexico and Berlin.
Experts from the University of new Mexico and Berlin”s Humboldt University found that people with a higher IQ have fewer connections in the cerebral cortex.
As the authors of interesting research, they analyzed the brains of volunteers from the two groups. The first consisted of 259 people in the age from 18 to 40 years, the second – 498, their age ranged from 22 to 36 years. Analysis of the morphology of the neurons was carried out using diffusion magnetic resonance imaging (MRI). This non-invasive technique allowed the scientists to measure the amount of dendrites in the cerebral cortex. All participants also passed an IQ test. Scientists compared the results of two measurements and came to the conclusion that people with higher IQ have fewer connections between neurons in the cortex.
“Previous studies have suggested that large brains contain more neurons and connections, therefore, have more computing power, says Dr. Erhan the Jansom in an interview with the academic publication Science Daily. – We have demonstrated that the brains of intellectuals have, though meager, but highly effective neural connections. Means that they show high mental performance at a low activity of neurons”.
