Meeting Abstract 66.2  Wednesday, Jan. 6  Circadian oscillations in gene expression in the sea anemone Nematostella vectensis: the evolution of the animal circadian clock REITZEL, AM; BEHRENDT, L; TARRANT, AM*; Woods Hole Oceanographic Inst.; WHOI; WHOI atarrant@whoi.edu Circadian clocks provide biochemical cues for diurnal variations in physiology and behavior. In animals, circadian clocks are generally entrained by […]

Meeting Abstract 66.1  Wednesday, Jan. 6  Blastoderm patterning and gap gene interaction in the milkweed bug Oncopeltus fasciatus BEN-DAVID, J; CHIPMAN, A.D.*; The Hebrew University of Jerusalem; The Hebrew University of Jerusalem ariel.chipman@huji.ac.il The early embryo of the milkweed bug, Oncopeltus fasciatus, appears as a single cell layer – the embryonic blastoderm – covering the entire egg. […]

Meeting Abstract 66.6  Thursday, Jan. 6  Using bio-robotic tools to explore muscle force-length and force-velocity properties in aquatic locomotion RICHARDS, Christopher T.*; CLEMENTE, Christofer J.; Harvard University richards@fas.harvard.edu Understanding swimming biomechanics is challenging because of the complexities of fluids and the poor knowledge of neural input versus muscle output. Recent bio-robotics advances explore how various limb motions […]

Meeting Abstract 66.5  Thursday, Jan. 6  THE MUSCLE ACTIVATION PLOT AS A GRAPHIC UNIT INTERFACE FOR VOICE SIMULATION ACROSS SPECIES. TITZE, I.R.*; RIEDE, T.; Uni. of Utah, Salt Lake City; Uni. of Utah, Salt Lake City ingo.titze@ncvs2.org Voice simulation utilizes sophisticated computational methods from two well-developed disciplines, mechanical engineering and physiology of musculo-skeletal systems. Fluid-structure interaction principles […]

Meeting Abstract 66.3  Thursday, Jan. 6  Neuromuscular Activation Dynamics from Different Types of Motor Units for Predicting Muscle Forces During Locomotion LEE, S/SM*; BIEWENER, A/A; DEBOEF MIARA, M; WAKELING, J/M; Simon Fraser University, Burnaby, Canada; Harvard University, Cambridge, MA; Harvard University, Cambridge, MA; Simon Fraser University, Burnaby, Canada sabrina_lee_4@sfu.ca Neuromuscular activation dynamics are critical to muscle force […]

Meeting Abstract 66.2  Thursday, Jan. 6  Energy absorption by muscle during steady and non-steady movement KONOW, N*; ROBERTS, TJ; Brown University; Brown University nkonow@brown.edu An important function of skeletal muscle is to absorb energy via active lengthening. This occurs in leg extensors during leg flexion and with changes in energetic demand—when running terrain slopes downhill or landing […]

Meeting Abstract 66.1  Thursday, Jan. 6  Active Muscle Enhances Rapid Perturbation Recovery in an Insect Limb. LIBBY, T.*; FULL, R. J.; Univ. of California, Berkeley tlibby@berkeley.edu Passive, intact limbs of cockroaches recover from large impulses in less than 40 ms, sufficient for complete recovery from a perturbation at the onset of swing phase. Such capability could insure […]
