size of brain

on average the adult human brain weighs 3.5 lbs ( smallest on record weighed 3 lbs largest on record weighed 5)and is about 6 inches long. It is a dark pink when alive and light grey when dead. It looks very similar to brain coral.

I hope that helps answer some of your questions about the brain.
