Sure, but the brain is a Turing machine, albeit with hardware acceleration of key functions (e.g., edge detection in the visual cortex). Mathematics, not chemistry, structures the problems it solves, if not the algorithms and heuristics involved. It's utterly fascinating to see how nature tackles the same problems that we solve independently using completely different tools.
