Gareth Cook in the NYT:

The race to map the connectome has hardly left the starting line, with only modest funding from the federal government and initial experiments confined to the brains of laboratory animals like fruit flies and mice. But it’s an endeavor heavy with moral and philosophical implications, because to map a human connectome would be, Seung has argued, to capture a person’s very essence: every memory, every skill, every passion. When the brain isn’t wired properly, it can lead to disorders like autism and schizophrenia — “connectopathies” that could be revealed in the map, perhaps suggesting treatments. And if science were to gain the power to record and store connectomes, then it would be natural to speculate, as Seung and others have, that technology might some day enable a recording to play again, thereby reanimating a human consciousness. The mapping of connectomes, its most zealous proponents believe, would confer nothing less than immortality.
