...HORIZON Researchers are exploring two related molecules, gaba and glutamate, that are responsible for 90% of chemical signaling in the brain. 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...
...HORIZON Researchers are exploring a similar technique that sends an electrical current through the vagus nerve--a major conduit wiring the heart and intestines--which then delivers it to the brain. Another approach, called regional transcranial magnetic stimulation, uses an electric coil shaped like a figure eight to create a magnetic field inside the pre-frontal cortex, which plays a key role in mood regulation...
