Simply that certain brain waves correlate with some definition of awareness of your surroundings.
I'd imagine its pretty hard to be certain that a brain-dead person can't perceive his or her surroundings, however.
- TomMckenny 9y agoBut someone with far less brain activity than, for example, an unconscious patient on an operating table is not going to be more conscious.
- Waterluvian 9y agoIts a rational, intuitive assumption. But we learn new things all the time.
- zipwitch 9y agoGiven that there are people walking around living perfectly normal lives who have only a small fraction of normal brain mass, I'm always skeptical of definitive pronouncements regarding conciousness.
- logicallee 9y ago>Given that there are people walking around living perfectly normal lives who have only a small fraction of normal brain mass, Could you find a link perhaps? I Googled the end of what I just quoted but didn't find anything...
- monkpit 9y agoHow would a disembodied brain even be capable of being “aware of its surroundings” without any sensory information?
- Razengan 9y agoSome sense of touch/pressure/temperature as the skin does, perhaps? Consider how we can feel physical sensations in dreams without any physical source, or “phantom limbs” that amputees are sometimes said to feel.
- digi_owl 9y agoThat is not being aware, that is the brain making stuff up from noise.
- swiley 9y agoHuman brains can’t sense any of that, idk about pig brains.
- ghkbrew 9y agoFun fact: the retina and optic nerve are outgrowths of the developing brain, and commonly considered part of it. So technically a bare brain can see.
