Caption: Tympanal mechanics and impedance conversion in the anterior tympanic membrane of Copiphora gorgonensis (Orthoptera: Tettigoniidae: Copiphorini). The video illustrates the rocking motion of the tympanum and tympanal plate at 23kHz. Similar motion is observed at other frequencies as well. This video relates to a paper that appeared in the Nov. 16, 2012, issue of Science, published by AAAS. The paper, by Fernando Montealegre-Zapata at the University of Lincoln in Lincoln, UK, and colleagues was titled, "Convergent Evolution Between Insect and Mammalian Audition."
