Question

What accounts for more than 60% of the total bran weight?

I looked in my book and it said one part accounted for 85% and then another part said 40%. I think it's the cerebral hemispheres, but I don't know for sure.

Answer 1

The Cerebral Cortex

Answer 2

The cerebrum or cerebral hemispheres is correct. Technically, the cortex is only the outer portion of the cerebrum, the gray matter, consisting mostly of cell bodies of neurons.

I hope this helps a little more. Thanks for asking.
