YOu, in fact, do not know that there is no consciousness without neural activity. You cannot demonstrate that.In fact, let me go this far ~ no one knows where the seat of consciousness resides, and that's a scientific fact!

All available evidence points to the brain as the seat of consciousness; therefore the burden of proof rests with those who believe that consciousness can somehow exist without brain activity.

A breathless world await your evidence.

Lots of things can't happen without brain activity, but that has nothing whatsoever to do with proving "consciousness".

Really and truly no one knows. For all we know there's an underlying electronic network of some sort, or maybe something even more basic than that.

The brain does seem to be an input/output device of somesort, but so, too, is the slave circuit that drives the screen on my CRT.

It might be noted that creatures can exhibit behavior without any nervous system at all. Plants can do this. Microbes also. Behavior is taken to be a sign of consciousness, if not self-consciousness.
