Is there brain function during a cardiac arrest?

For a brief time: When the heart stops circulating blood to the brain the functions of brain cease after about 5 minutes. If CPR is performed the brain function can return. However prolonged CPR may not get enough blood to brain to prevent brain damage even if heart recovers.
