Some scientists claim that our brains grew because of our consumption of meat. That your typical vegan diet couldn't support the huge amount of energy required by the human brain.

I think they might be on to something here: The vegans I have known have could not hold a thought for more than a second or two. They were airheads.

I know that if a breastfeeding mother follows a vegan diet, it is recommended that she takes fish oil, in order that the baby's brain not be malformed.

It turns out the in Sear’s book “Zone” you learn that without the ballast of protein the body enters a quasi-carbo-poisoned mode where the whole body is stressed and this includes the brain.
I remember seeing a movie about deprogramming and the first thing they did was replace the coolaid and brownies with toast and peanut butter.
