Frogs turn out to be some of the most sensitive organisms to substrate-borne vibrations.
This sensitivity resides in the inner ear and the otolith organ sacculus almost exclusively responds to vibrations. I am currently investigating response properties of vibration sensitive neurons in the saccular nucleus in the frog CNS with professor Wolfgang Walkowiak, Cologne. The experiments are performed on isolated brains that can be kept alive for up to a week. An ongoing project concerns behavioral studies of vibration sensitivity. We have published a paper on the calling behavior, one is in prep and further work on the calling behavior of this species is planned.
