DO PEOPLE USE ONLY 10% OF THEIR BRAINS?

The following report in a belated issue of the 'Scientific American' throws some light on the foregoing question.

Nevertheless, I am intrigued by the concluding remark in the report:

". . . out of all the brain's cells, only 10 percent are neurons; the other 90 percent are glial cells, which encapsulate and support neurons, but whose function remains largely unknown.

Ultimately, it's not that we use 10 percent of our brains, merely that we only understand about 10 percent of how it functions."
