Because they control so much of the brain's activity, the trick is to fine-tune their levels in ways that relieve depression but don't affect other brain functions. Other targets of drug development: the sex hormone testosterone (a transdermal patch proved effective in a recent clinical trial for men); the stress hormone cortisol, which researchers are trying to regulate with the abortion drug RU 486 and compounds called CRF antagonists; the dynorphins (the evil twins of feel...

Now, with the prospect of a possible fine of up to $9 billion on the horizon, he has to craft a viable reorganization plan for the largest corporate bankruptcy in U.S. history, involving $107 billion in assets.
