Interesting thread.
A lot of animals will eat the brain first out of a young animal who's skull hasn't quite hardened yet. I've seen my dog to it to a kitten.
I've thought of making beef brain smoothies. The thing that has kept me from them is the fear of prion diseases. One thing going for them is that these diseases can't be killed by normal cooking temperatures so there's no difference there in eating them cooked or raw.
Eating thymus gland, AKA sweetbreads is also a concern when it comes to prions and I've been eating them raw for many years, lately a half pound a day; so I think I should probably just go for it and give brains a try.

https://en.wikipedia.org/wiki/Brain_as_foodLooks like they are quite expensive on Amazon. I think they are really cheap at the meat market. If I were to try them I would put them in a tupperware dish and freeze them into molds to slightly thaw and slice with my slicer and then place the slices in plastic bags to store in the freezer to take one out and wack them on the counter, then dump them into my food processor and slowly add water whenever I want to make a brain smoothie.
I never knew that brains contained a lot of omega 3. I wonder if the brain they sell at the butcher shop also contains Pituitary, Hypothalamus and Pineal Glands, like mentioned in the Amazon link I quoted. That has me quite interested. My guess is it probably does. Brain also contains a lot of cholesterol but I already get quite a bit from the half pound of raw liver I eat a day. All this is a game changer and I'm seriously considering eating it after reading about it more...
Think I'll ask for some at the supermarket next time...
