[Star Wars] How does the Stun setting work on an Imperial Blaster?

We know how a normal blaster shot works, a bolt of plasma contained in a magnetic sheath, but the Stun setting looks and acts completely different. Instead of a linear bolt, it looks more like a wave or a pulse, and it doesn't look like plasma. So what exactly is happening, how does it work?

The stun setting bypasses the gaseous ammunition that normally gets fired from the weapon, and instead fires from a secondary emitter on the barrel. This emitter unleashes an electromagnetic pulse that overloads the target's nervous system. 

Speculation: The stun setting is likely just as lethal to several species, and is probably lethal to humans in certain circumstances. But it's adequate as a general stun setting for the vast majority of living targets.
