with a virus that induced their brain cells to glow, or fluoresce, anytime an
electrical impulse was triggered by something the mouse saw.
As for those patients whose brains are trapped in inanimate bodies, implants that pick up
electrical impulses can already translate neural signals to control a cursor, move a wheelchair, or say hello, although they are not now suitable for people

electrical nerve
impulses to the optic nerve and into the brain.

with a myelin sheath that allows these
electrical impulses to be conducted at a high speed.
Traditionally, it was thought that the there were three main factors that derived from CNS activity that subsequently affected EMG amplitude: the motor unit recruitment extent, the motor unit firing frequency, and the synchronisation of these
electrical impulses (
with greater synchronisation perhaps implying greater neural drive from the CNS)(see review by Behm, 1995).

with whirlwind of
electrical impulses forming in the right (RA) and left atria (LA) instead a single organized
impulse from the sinoatrial (SA) node causing the atrial muscle to fibrillate (quiver) instead of an organized contraction to fill the right (RV) and left ventricles (LV).

Gunnar Davis is a heavy weapons specialist
with an assault rifle as a primary weapon and a pistol for a secondary weapon, while his special abilities include Shockwave which sends a powerful
electrical impulse that knocks down enemies; Stasis projects a stasis field that stops time for enemies albeit while simultaneously protecting them from incoming fire, but could still be useful to strategically change position, finding cover or running past a large group of enemies; Barrier creates a protective energy bubble that prevents damage from being received by Gunnar; and Storm hits enemies
with a lightning strike.

Given that premise, our job is to work out the details and they have hardly been all worked out, but when considering what premises are available upon which to base an «ethics» it seems one that starts
with an axiom that an objective ethics is possible offers a helluva lot more potential for what we want, for what serves the life of a rational, sentient being, than one that says it's a matter of your bowels, or random
electrical impulses in your brain or that your mind that tells you to murder my children is the moral equivalent of my mind telling me to protect yours.
