Are all brain activities computable?

Question

Computable in principle.

Answer 1

Since the brain is finite they would have to be. You would just need a big enough computer. Andy the word "computable" has a specific meaning in computer science. It means capable of being computed on a sufficiently large computer. It doesn't mean that the computer exists. It also has nothing to do with speed. All finite computations are computable.

The principle of computational equivalence says that systems found in the natural world can perform computations up to a maximal ("universal") level of computational power, and that most systems do in fact attain this maximal level of computational power. Consequently, most systems are computationally equivalent. For example, the workings of the human brain or the evolution of weather systems can, in principle, compute the same things as a computer. Computation is therefore simply a question of translating inputs and outputs from one system to another.

Answer 2

No. Neural synapses and the mass of activity that occur in them are too complex for even the most advanced computer. Autistic savants can perform complex tasks involving computations etc. even quicker than computers can.

Answer 3

Id have to agree with andy here

And by the way I totally think andy is like a sleeping giant. He just lays low until he sees a good question :D

Answer 4

right now? no.

in principle? yes.

Answer 5

We do not know yet.
