I think the complication here is that brains are probabilistic, which admits the possibility that they can’t be directly related to non probabilistic computability classes. I think there’s a paper I forget the name of that says quantum computers can decide the halting problem with some probability (which makes sense because you could always just flip a coin and decide it with some probability) - maybe brains are similar
