Albert Einstein, had a higher ratio of glia-to-neurones (i.e. more glia) than that of the doctors’ brains his was compared to. Furthermore, animal studies determine that, as intellect rises, the glia-to-neurone ratio also increases. Therefore, an indicator of brainpower could be an individual’s glia-to-neurone ratio, possibly because each neurone receives more glial attention and so operates more efficiently. If this were deemed an accurate measure of intelligence, the Minke whale would be the smartest species, having the highest glia-to-brain ratio of any species – 5.5 times greater than humans’.
