What if you replace all the neurons and the person is suddenly stuck with no short-term memory and aphasia? Clearly your replacement neurons are defective. At which point are they not? Is that point distinguishable from normal neurons?

What is this counterfactual? We're talking about replacing the neurons one by one, slowly. When would the loss of memory happen?

Is a person with no short-term memory and aphasia still conscious?
