Could a person control their face after being decapitated?

You know how the brain sends signals to the nerves in your body, which in turn moves your body? And you know the phrase 'running around like a headless chicken' is actually true because a headless chicken has lived for over 3 years? Well could we not move our heads after decapitation, since the nerves are still there, and so is the brain.. It's not like everything is completely shut down in the split second that you're killed.. So is this possible? Could we actually still move our faces after decapitation?
