Meeting Abstract 39.6  Sunday, Jan. 5 09:15  Does advanced age alter in vivo muscle operating length? HORNER, AM*; MOURADIAN, G; GROGAN, S; ROBERTS, TJ; Cal State San Bernardino; Brown University; Brown University; Brown University anghorner@gmail.com Advanced aging is associated with muscle weakness, stiffness, and decreasing joint range of motion. The operating lengths used by aged muscle in […]

Meeting Abstract 39.2  Sunday, Jan. 5 08:15  Compliance, activation and the force-length relationship in skeletal muscle HOLT, NC*; ABBOTT , EM; AZIZI, E; Univ. of California, Irvine; Univ. of California, Irvine; Univ. of California, Irvine natalie.c.holt@gmail.com In vivo muscle performance is modulated by varying the level of muscle activation, both by changing activation frequency and the number […]

Meeting Abstract 38.7  Sunday, Jan. 5 09:30  Visual opsins in non-visual photoreceptors: A common solution for extraocular light detection KINGSTON, A*; CRONIN, T; Univ. of Maryland, Baltimore County; Univ. of Maryland, Baltimore County anahm1@umbc.edu Non-visual photoreceptors are common throughout the animal kingdom. Most previously described non-visual photoreceptors function using opsins that are not typically used for vision. […]

Meeting Abstract 38.1  Sunday, Jan. 5 08:00  The role of the lateral line system in foraging by zebrafish larvae CARRILLO, A.*; GARCIA, D.A.; MCHENRY, M.J.; Univ. of California, Irvine; Cerritos College; Univ. of California, Irvine andresc2@uci.edu Adult fish use the lateral line system to localize prey by sensing water flow, but it is unclear when this ability […]

Meeting Abstract 38.6  Sunday, Jan. 5 09:15  Seeing double: the ontogeny of light sensitivity in stomatopod crustaceans FELLER, KD*; COHEN, JH; CRONIN, TW; University of Maryland Baltimore County kfeller1@umbc.edu In addition to having unique adult visual systems, stomatopod crustaceans also undergo a unique process of eye development. Just prior to metamorphosis, an adult retina and associated neuropils […]

Meeting Abstract 38.5  Sunday, Jan. 5 09:00  Photoreceptors with dual sensitivity to UV and visible light are in the larval eyes of the basal arthropod Limulus polyphemus BATTELLE, B-A.*; KEMPLER, K.E.; PAYNE, R.; Whitney Lab.
