I am not sure what else you mean by ‘at a fundamental level’.
Get enough neurotransmitters of the right type at the receptors of each neuron and it fires. At the level of chemistry that’s very much computable. It’s only by digging one step below that and saying you need to simulate quantum effects for some reason that doing so in a chip becomes an issue.
