Our study group met this AM, so naturally we spent some time on this. I tried to draw it here for you, but it wouldn't post right. So here's what we think: E-I would be very high, A-R and D-A hiding out just underneath, and S-H just behind those two. Now, will you please tell us the right answer? We had a wonderful time exploring it from all angles this morning and, of course, never got to the syllabus!! Incidently, do you think that two or more affects happen at the same time, or do they oscillate? I seems that if they are due to rates and levels of neural firing they must be oscillating.
