Sorry, brains aren't my specialty, so I can't answer your question. But
just as an interesting point, I seem to recall reading once that
dolphins sleep half their brain at a time, so that they can keep
swimming and breathing using the remaining, awake half. They then
periodically switch halves, so that the whole brain is rested. Can
anyone else confirm this? Perhaps a large brain is required so that
certain functions can be duplicated.
