For what?: It's is well known that vagal stimulus may lower the heart rate (useful in tachycardias )lowers the production of acid in the stomach( vagotomy surgery for peptic ulcers) and also can suddenly stop hiccups. Maneuvers that stimulate the vagus( could be dangerouse): massaging carotid bulb in the neck, putting pressure to the eyeballs, putting pressure to the forehead, gag reflex, valsalva.

VNS: Vagus nerve stimulation is a neuromodulation system that provides constant electrical stimulation of the vagus nerve in the neck. It is indicated for epilepsy and depression. The exact mechanism of action is unknown.

Almost. Depending on the on and off time the output current is delivered in pulses when on (typically 30 seconds) then the stimulus is off for a period of time (typically 5 minutes)

Vagal Nerve Stim: works by modulating activity of the Nucleus Solitarius in the brain stem. Pulsatile electrical impulses are delivered from a signal generator implanted under the skin to the left Vagus Nerve. The frequency and strength of the signal is adjusted to maximise seizure control, mood, attention and other parameters over time.
