Walt Disney was right.*

What does "activity" mean here exactly — are we talking about electrical signals, or something closer to functional neural circuits? Big difference for the cryonics crowd.
From 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."

Thinking about it, that's almost as impressive as what the scientists did.
