Can the brain still be active after death?

Yes, the brain can remain active after the heart stops, with studies showing bursts of organized electrical activity, including gamma waves linked to memory and consciousness, for seconds to even minutes or hours after clinical death, suggesting the brain might "replay" life events or have a final surge of function before shutting down completely. While this activity shows the brain doesn't instantly die, it doesn't necessarily mean awareness persists, as the cerebral cortex can function without oxygen for a short time after the heart stops, according to this YouTube video.
