WARNING: contains scenes of animal testing; Educational film that explores science and medicine through cinematography microphotography and medical photography. Hibernation Trigger: The Blood-Borne "Trigger" for Natural Mammalian Hibernation shows step-by-step experimental studies, or animal testing, of hibernation with chipmunks and woodchucks. Doctors take blood samples, perform operations, and induce hibernation to study and film these animals and their bodily functions in states of activity versus hibernation.
