You probably mean a boolean value. A bit has no meaning outside of its 
context.

Consider quanta. Consider a single spike. Consider neurotransmitter 
vesicle packets.

Sorry, but you are somewhat misguided. Go ask Marquis de Alta Vista for 
Claude Shannon, and information thery. Then consider the 
indistinguishability of random and pseudorandom noise, and sampling 
quantization vs. number of bits. If this still does not help, look up 
Bekenstein's limit. So there.
