The Synaptic Connections of a Multifunctional Network in Tritonia diomedea
Meeting Abstract 80.1 Sunday, Jan. 6 The Synaptic Connections of a Multifunctional Network in Tritonia diomedea CAIN, Shaun D; Eastern Oregon University shaun.cain@eou.edu One of the emerging principles in neuroethology is the prominence of multifunctional networks in the control of behavior. In the sea slug Tritonia diomedea, for instance, the well described swim central pattern generator synapses […]
Role of a Compartmental Arousal System in Subtle Locomotory Speed Changes in a Mollusc
Meeting Abstract 80.2 Sunday, Jan. 6 Role of a Compartmental Arousal System in Subtle Locomotory Speed Changes in a Mollusc SATTERLIE, R. A.; Univ. of North Carolina Wilmington satterlier@uncw.edu Two types of speed change have been described in the pteropod mollusc Clione limacina; a dramatic change from slow to fast swimming, equivalent to a gait change in […]

Differential expression of melatonin receptor subtypes in the song control system of European starlings
Meeting Abstract 80.5 Sunday, Jan. 6 Differential expression of melatonin receptor subtypes in the song control system of European starlings UBUKA, T*; MARGULIS, J; CLEGG, S; BENTLEY, GE; Univ. of California, Berkeley ubukat@berkeley.edu The volumes of song control nuclei of songbirds, including Area X and HVC change across the breeding seasons. Besides the effects of seasonally-changing sex […]
The effect of morphological variation on the sensitivity of the lateral line system in zebafish larvae (Danio rerio)
Meeting Abstract 79.2 Sunday, Jan. 6 The effect of morphological variation on the sensitivity of the lateral line system in zebafish larvae (Danio rerio) VAN TRUMP, WJ*; YIP, KD; MCHENRY, MJ; Univ. of California, Irvine; Univ. of California, Irvine; Univ. of California, Irvine wvantrum@uci.edu The mechanosensors of the lateral line, called neuromasts, are comprised of bundles of […]
Insight into the neural encoding of water flow; morphological and functional heterogeneity in the lateral line neurons of larval zebrafish
Meeting Abstract 79.4 Sunday, Jan. 6 Insight into the neural encoding of water flow; morphological and functional heterogeneity in the lateral line neurons of larval zebrafish LIAO, James C.*; FETCHO, Joseph R.; Cornell University jl10@cornell.edu Fishes detect water flow using clusters of directionally sensitive hair cells, which are distributed along the body surface as discrete neuromasts. Appropriately […]
Functional Consequences of Morphological differences in Stingray Lateral Line and Electrosensory Systems
Meeting Abstract 79.3 Sunday, Jan. 6 Functional Consequences of Morphological differences in Stingray Lateral Line and Electrosensory Systems JORDAN, L.K.; Univ. of California, Los Angeles ljordan@ucla.edu How well can form predict function in sensory systems? Elasmobranchs demonstrate remarkable sensory capabilities with high interspecific diversity, particularly in the mechanosensory and electrosensory systems of batoids. These systems allow elasmobranches […]
Fluid-structure interaction in the fish lateral line system
Meeting Abstract 79.1 Sunday, Jan. 6 Fluid-structure interaction in the fish lateral line system MCHENRY, M/J*; STROTHER, J/A; VAN TRUMP, W/J; U.C. Irvine mmchenry@uci.edu A tremendous diversity of aquatic animal sense water flow with ciliated receptor organs. The sensitivity of these organs depends on their mechanical interactions with the surrounding fluid. In order to understand these dynamics, […]
