You would have thought that a human head would lose consciousness immediately upon decapitation. Apparently not.

There have been some accounts of the decapitated heads showing some sign of awareness for a few seconds (up to 30secs in one account). Naturally the expressions on the heads would be too gruesome to describe properly.

Some of these accounts are dismissed as muscle spasms, but there are those that cannot be so dismissed. If you ask a head to blink its eyes and it does so for a few seconds... is it muscle spasm?

The Damn Interesting website captures some of these accounts.
