Title: % Neurons in cerebral cortex?
Post by: Transcendent on June 08, 2010, 12:05:14 pm
Just wondering, what percentage of the brain's neurons are contained in the cerebral cortex?

And if you imagined there was no skull, what % of the brain's neurons would be visible to the observer on the outside?

I thought it was 70%, 2/3rds or something. Ive never seen a question like that on a practice exam. Its at the very start of the chapter 2 (?) grivas though.

same. I am sure I saw somewhere that in the CNS, 70% of neurons are in the cerebral cortex

The book actually states 1/3.
