How would Koch see a mechanism where neurons or other cells in a human brain are sequentially replaced over time with synthetic components that simulate their function, is the consciousness lost along the way? Is there consciousness as long as there is at least one biological cell left?

I wonder if an intelligence higher than ours were to figure out exactly how our brain worked. Every neuron, every synapse, every hormone and neurotransmitter.. How memories were made, stored and retrieved. Would we appear to them to merely be "simulating" consciousness through the use of these mechanisms.

You should write a book, "The Cyborg of Theseus" :)
