Brains of smarter people have bigger and faster neurons

Scientists working within the Human Brain Project have for the first time uncovered a direct relation between brain cell size and IQ level. As they describe in the journal eLife, larger neurons in the so-called temporal lobe of the brain that generate electrical signals with higher speed are related to faster processing rates and intelligence level as assessed in standard IQ testing.https://www.humanbrainproject.eu/en/follow-hbp/news/brains-of-smarter-people-have-bigger-and-faster-neurons/
