![]() ![]() The work builds on an existing hierarchal model of behavior, but goes further in explaining how much of sea star locomotion happens locally versus globally. candidate, were joined by Matt McHenry, associate professor of ecology and evolutionary biology at the University of California, Irvine Amy Johnson, professor of marine biology at Bowdoin College and Olaf Ellers, research associate in biology and mathematics at Bowdoin College. The researchers, including Professor Eva Kanso in USC Viterbi's Department of Aerospace and Mechanical Engineering and Sina Heydari, a USC Viterbi Ph.D. #Eva kanso usc how toIn other words, once the sea star provides an instruction on which way to move, the individual feet figure out how to achieve this on their own, without further communication. The answer, from researchers at the USC Viterbi School of Engineering, was published today in the Journal of the Royal Society Interface: sea star couple a global directionality command from a "dominant arm" with individual, localized responses to stimuli to achieve coordinated locomotion. For years, researchers have wondered exactly how a sea star accomplishes this synchronization, given it has no brain and a completely decentralized nervous system. Any one tube foot on a sea star can act autonomously in responding to stimuli, but coupled together, they can synchronize their motion to produce a bouncing motion-their version of running. ![]()
