I'll agree with all that, and add that you'll almost never hear the term "triune brain" used by a practicing neuroscientist. In fact, I just did a 1966-2003 Medline search for any cooccurrence of the words "triune" and "brain" in abstracts of published papers, and there were only 10 hits. --David Epstein [EMAIL PROTECTED] --- You are currently subscribed to tips as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED]
