Excellent. Thanks Peter. What I am hoping to do, perhaps vainly trying to
do, is find out what really causes depression. This serotonin emphasis
ignores the multiple means by which depression can arise, we are attacking
the problem from the wrong angle. There has to be a better way. Many months
to go yet. ...
I want to know which efferents drive serotonin prodn in the raphe nuclei. I
suspect serotonin depletion is an end consequence of a long chain. The final
common pathway of a number of potential processes.
