Death rattle of a decapitated brain: "But Coenen noticed something else. He kept the EEG running for several minutes after decapitation and noticed a 10-second wave of electrical activity in the rats' brains. The wave appeared 50 seconds after decapitation in rats that had been awake, and after 30 seconds in sedated animals...
Coenen thinks the wave could represent neurons' electrical potentials collapsing."
