I'm also skeptical of the salmon study, and I would love to see replication results, because another alternative explanation is that, even after clinical death, the brain tissue may still weakly react to stimulis: the "fresh" fish would have been kept in ice due to chain-of-cold requirements (and humans can survive for 30 minute in hypoxia, and recover: https://abcnews.go.com/Health/hypothermia-save-boy-trapped-i..., turtles up to 6 month https://www.openaccessgovernment.org/survive-without-oxygen/...) and other tissues have shown similar feats (heart tissue in the same article)
Actually, it'd be sad, because for all we know, dead people could have this limited consciousness without being able to communicate, just like the coma patients!
