How is it possible for insects to survive after they've had their head removed?
My understanding was that heart muscle, being myogenic, is not controlled by the brain and heart rate can keep at a steady pace -- even outside the body (if provided with oxygen etc.) . I hope I didn't misunderstand since this is one of my favorite useless-facts to bring up when a conversation goes awkward and silent and there's nothing to talk aboutHumans- heartbeat and breathing are under control of the brain. Remove the brain and breathing and heartbeat go away.
