No, at least not when you define death as zero EEG. There are still some random neurons firing after blood flow ceased, but without oxygen supply, the brain stops working rapidly. There is a myth that beheaded people are still awake for seconds, but that`s because motoric neurons firing can cause seemingly controlled movements. Consciousness and all higher brain functions disappear milliseconds after oxygen supply is gone.
