Mammalian Dive Reflex

Students in Maren Anderson's Marine Science course explore reflex circuitry in the nervous system and the effect of sensory stimuli on efferent output by splitting into small groups and selecting one "diver" to dunk their head in water in a variety of contexts, such as with a snorkel, with a facemask, and more. The other members of the group track the diver's reactions using a pulse oximeter.
