Re: The Brain

I saw nothing which attacked you personally.  If you could give us an idea
of your background, we could write trying to match your knowledge of
anatomy and physiology.

Today's animals use all the full brain -- looking from the lifecycle time
frame.  And as pointed out, within the limits of keeping a very energy
expensive organ running, some redundancy exists.

I know the number for humans, but not for birds or dinosaurs.  Physiologist
can look at the circulatory system and measure arterial blood supply
vessels.  Using the ratio of internal diameter, they can gauge which organs
are getting what % of the blood supply and, by consequence, more oxygen.
Human brains get more blood than their mass would suggest.

You would do well to ask one question and get clear answers.

Take care,
