ROBERTSON, R.M.; Queen’s University, Kingston: Modulation of neural circuit operation by prior environmental stress Many organisms are exposed to harsh environmental conditions that may impair the operation of vital neuronal circuits, such as those controlling locomotion and ventilation, and imperil the animal before these conditions directly cause cell and tissue death. Prior exposure to extreme […]

PIRTLE, T.J.*; SATTERLIE, R.A.; Arizona State University; Arizona State University: Modulation of Swimming Speed in Clione Limacina An animal must modify its behavior to a changing environment. Neuromodulatory mechanisms intrinsic to the nervous system shape the cellular properties of neurons to ultimately adjust behavior. Modulation of neurons comprising the swim system of the pteropod mollusk, […]

SATTERLIE, RA; PIRTLE, TJ; Arizona State University; Arizona State University: Mechanisms of Swim Acceleration in the Pteropod Mollusc Clione limacina The pteropod mollusk, Clione limacina, swims by rhythmic dorsal-ventral flexion of a pair of wing-like parapodia. Usually, Clione swim slowly and continuously upward to maintain a stable position in the water column. Variability in locomotor […]

KLOSE, M.K.*; ROBERTSON, R.M.; Queen’s University: Heat Shock-Mediated Thermoprotection of Insect Neuromuscular Junctions Protection of cells and circuits from the deleterious effects of various environmental stresses can be induced after a brief initial stressful insult such as a heat shock or anoxic shock. The goal of this project is to understand the mechanisms involved in […]

MILLAR, A.G.; ZUCKER, R.S.; CHARLTON, M.P.; ATWOOD, H.L.; University of Toronto; University of California, Berkeley; University of Toronto; University of Toronto: Cellular Mechanisms of Synaptic Differentiation in Crustacean Motor Neurons We are examining mechanisms governing transmitter release efficacy at two vastly different crustacean motor neurons. Phasic nerve terminals release 100-1000 fold transmitter per action potential […]

BOUYER, L.J.*; ROSSIGNOL, S.; CRSN, Univ. of Montreal; CRSN, Univ. of Montreal: Adaptive locomotor capacity of chronic spinal cats following changes in sensory feedback. To further address the question of spinal plasticity, we used 2 complementary denervation protocols. In protocol #1, a motor denervation was performed, cutting the nerve to ankle extensors Lateral Gastrocnemius and […]

ROSSIGNOL, Serge; Universite de Montreal: Adaptive Mechanisms of Spinal Locomotion in Cats My work has concentrated on various aspects of the neural control of locomotion in the cat, including descending, sensory and spinal controls. A long standing interest has been the recovery of treadmill locomotion with interactive training after complete lesions at T13 in adult […]

SOKOLOWSKI, M.B.*; BEN-SHAHAR, Y.; ROBINSON, G.E.; University of Toronto: A Role for cGMP-Dependent Protein Kinase in Foraging Behavior in Fruitflies and Honeybees TBA

SHERIDAN, Mark A.; KITTILSON, Jeffrey D.; North Dakota State University; North Dakota State University: The Role of Somatostatins in the Regulation of Metabolism Somatostatins (SSs) are a structurally and functional diverse family of peptide hormones. Among the vast array of biological functions coordinated by the SSs are secretotropic effects as well as a host of […]

HOULIHAN, D.F; MARTIN, S.A.M.; University of Aberdeen: Protein metabolism in fish; gambling on proteomics. Protein metabolism in animals involves a balance between protein synthesis and degradation resulting in net gain or loss of proteins in an organism. Although protein synthesis is stimulated by feeding and growth is correlated with an increase in protein synthesis, rates […]
