The brain is most certainly a turing machine.
- bbcbasic 10y agoThe brain can emulate a Turing machine but not necessarily vice versa
- MawNicker 10y agoA turing machine can simulate the whole universe and everything in it.
- FreeFull 10y agoI don't see a good reason why a turing machine can't simulate a brain, or even a whole universe
- andrepd 10y agoThanks, that has sure assuaged my qualms -.-
- MawNicker 10y agoThe brain would need to leverage quantum effects to achieve hyper-computation. Otherwise it follows the same rules as other turing machines. Here's a quote from Scott Arronson: "Indeed, I see no evidence, from neuroscience or any other field, that the cognitive information processing done by the brain is anything but classical." -- http://www.scottaaronson.com/blog/?p=1951 http://www.scottaaronson.com/blog/?p=1951 Notably this is from a post discussing quantum effects as a potential explanation for consciousness. There's still no evidence for that either. Also, if true, it would only sit atop a classical cognitive process which acted as a turing machine. That or a horde of tiny turing machines.
