Yes. There was also at least one case where a chicken had been decapitated but, because the brainstem remained intact the chicken went on to live several more years only dying because it choked on the watery feedpaste it was fed with using an eye dropper.
That's not limited solely to chicken either, destruction of the central nervous system usually causes the body to immediately ragdoll but people have been known to complete some simple action after being killed by mortal head injury. Such as a US Marine assistant machine gunner in the process of reloading Browning machine gun took a rifle round to the head which blew the top of his skull off but yet managed to close the top cover of the MG and tap the gunner on the shoulder to indicate the gun was ready to fire before expiring.
Another was a pilot aboard an Independence-class carrier in the Battle off Samar, he was decapitated by shrapnel while running across the flight deck his body continued to run another 9 yards before collapsing.
Gruesome stuff that.
