Happiness Is A Warm Electrode 199
sufijazz writes "A story by Gregory Mone on the Popular Science website talks about trials to use deep brain stimulation to cure chronic depression. It's a deeper exploration of the 'brain pacemaker' discussed here on the site before, and a practical application of research discussed even earlier. Why the pulses affect mood is still unclear, but scientists believe that they may facilitate chemical communication between brain cells, possibly by forcing ions through nerve fibers called axons. In turn, this may trigger the release of mood-regulating chemicals like serotonin and norepinephrine. Similar trials are being conducted in other places. Exact numbers are hard to ascertain, but it's estimated that fewer than 50 patients in North America are walking around with wires in their brain."

That said, everyone does react differently, and some can have the side-effect of sending you into a manic state (which can include the symptoms you described). Usually a dosage or timing adjustment can fix this.
Drug tuning is still more art than science. A new drug to treat depression is considered a great success if 50% of the users experience a 50% improvement. Many successful regimens involve combinations of drugs, and it can take a year or more to find the right combination. (It doesn't help that many common drugs take over a month to have any effect.)

It's interesting work: they're apparently much more effective for transmitting a signal than picking up signals, so the idea of using them for artificial limbs or thought-control of aircraft has never really worked well.

Unhappy is what normal people feel when something exists to make them unhappy.
Depression is what depressed people feel all, or most of, the time, for no apparent reason.
Anti depressants allow a depressed person to feel normal - i.e. they can feel unhappy again, as well as happy and everything in between. It reconnects their emotional response to everything, rather than being permanently, well, literally depressed.

Great question! If you mean "electrical frontal lobotomy" as in "a way to use electricity to separate the frontal lobes of the brain from the rest of the brain", then no I don't think it is. Then again, I'm no doctor, but I did read the article!
On the other hand, if you mean "electrical procedure that is supposed to cure mental illness and that a lot of people really want to believe in to the degree that they may be willing to overlook gruesome consequences for several decades", then maybe. Who knows? Once upon a time, people thought sliced brains were the best thing since sliced bread.
