Scientists revive activity in frozen mouse brains for the first time
- august- 7mo agoWhat does "activity" mean here exactly — are we talking about electrical signals, or something closer to functional neural circuits? Big difference for the cryonics crowd.
- MarkusQ 7mo agoFrom the article: "Microscopy showed that neuronal and synaptic membranes were intact, and tests for mitochondrial activity revealed no metabolic damage. Electrical recordings of neurons showed that, despite moderate deviations compared with control cells, the neurons’ responses to electrical stimuli were near normal. Hippocampal neuronal pathways still showed the synaptic strengthening or ‘long-term potentiation’ that underlies learning and memory."
- MarkusQ 7mo agoPretty cool. And we don't even need to tag it "In mice" because the headline says so up front. Thinking about it, that's almost as impressive as what the scientists did.
- nephihaha 7mo agoVery cool. Probably cool enough to condense gases.
