It doesn't have to be.
Neurons are created and die all the time. Replacing them one at a time, with their virtual equivalent, would not be entirely different to what is already happening.
- ajnin 6y agoNot really, neurons are one of the few types of cells that don't undergo a cycle of death/creation of new cells. The neurons you had when you were born are the same you have now. They probably encode a lot of information that would be lost if they died and were replaced by fresh cells.
- cblconfederate 6y agothere is some neurogenesis, and the assumption is the new cells integrate with existing circuits over time. However , in the scenario that single neurons are replaced with artificial copies with exact same synaptic weights, then yes they are functionally equivalent. It's already happening, with deep brain implants etc.
- WalterSear 6y agoThis is a myth. Neurogenesis changes with age and is mostly prevalent only in specific brain areas, but is a well investigated phenomenon. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3106107/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3106107/ https://www.nature.com/articles/nm1198_1313 https://www.nature.com/articles/nm1198_1313 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4812798/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4812798/
