Why thank you! Make me blush! lol The VNS is the Vagus nerve stimulator. It is like a pacemaker, It is implanted in the chest, and wires go up to the vagus nerve in the neck, and the doc programs it for different amounts of amps to go off and different intervals.. AND it goes up to the brain. Hopefully keeping the brain from misfiring. Mine goes off at 2.0 amps every 30 seconds for 30 seconds.
Hope this helps ya!
