What activation function does the human brain use?

Does the human brain use a specific activation function? I've tried doing some research, and as it's a threshold for whether the signal is sent through a neuron or not, it sounds a lot like ReLU. ...

Does the human brain use beam search for text generation?

As far as I understand, beam search is the most widely used algorithm for text generation in NLP. So I was wondering: does the human brain also use beam search for text generation? If not, then what?

If we achieve sentience using mutable hardware, will it be possible to make a copy of that "brain" and its active state?

Hardware comes in two forms, basically: immutable, such as RAM, and mutable, such as FPGAs. In animals, neurological connections gain in strength by changing the physical structure of the brain. This ...
