New Mind-Uploading Start-Up Can Only Preserve “Fresh” Brains

Y Combinator start-up Nectome believes they’re capable of backing up the mind for future digitization. Their process involves preserving every microscopic detail of the brain with a new, advanced embalming process paired with cryonics. It’s the ability to keep the connectome intact, or the web of synapses that connect neurons, that sets them apart from others pursuing similar preservation. As Technology Review points out though, what is “lacking is evidence that memories can be found in dead tissue.” Nectome has also received a large grant from the US government and 25 people have put a deposit down for the service—which is a fatal one, requiring the preservation of a fresh brain.
