Of cerebrum, cerebellum, brain stem, or limbic system, where does most of the brain's activity occur.

I BELIEVE IT IS THE CEREBRUM OF INFORMATION READ FROM MY TEXTBOOK AND A FEW ONLINE HELP SITES BUT AM NOT SURE.

Since it is the connecting portion between the brain and the body, it would have impulse traffic both ways — sensations ot the brain and action commands to the body. Although I am not absolutely sure, I would assume that this was the greatest amount of brain activity.

I hope this helps. Thanks for asking.
