VNS - Vagus
Nerve Stimulation (Wiki)
Typically a treatment for epilepsy, Vagus Nerve Stimulation
may provide the answer to
extreme disorders. Simply put, a small
pacemaker like contraption is connected up to, yes, your
vagus nerve. via a small cable under the skin;
the device itself is implanted at the base of
the neck. It sends frequent but mild
stimulation to your brain, resulting in an antidepressant effect amongst others. It is generally
regarded as more effective than drug therapy. Many people don't feel the shocks,
whilst others aren't so lucky. The energy levels of
the device can be toned down very easily to a
more acceptable level and can be turned off altogether
if it's causing unpleasantness.
