Photoexcitation of retinal rod photoreceptor cells involves the activation of cGMP enzyme cascade in which sequential activation of rhodopsin, transducin, and the cGMP phosphodiesterase in the rod outer segment constitutes the signal amplification mechanism. Phosducin, a 33-kDa phosphoprotein, has been shown to form a tight complex with the T beta gamma(More)
This project examines the choreography of high speed turns performed by Danio aequipinnatus, giant danio, with the goal of understanding the motions that allow this species to perform its highly efficient maneuvering. Observations of the turns were made using high-speed video to determine general characteristics which may then be applied to biomimetic(More)
