Meeting Abstract S1.10  Tuesday, Jan. 4  The frequency dependent recruitment of interneurons in the rodent spinal cord ZHONG, Guisheng GZ*; HUSCH , Andreas AH; HARRIS-WARRICK, Ronald RMH; Cornell University Ithaca; Cornell University Ithaca; Cornell University Ithaca gz33@cornell.edu Neuronal networks that control and coordinate locomotion such as swimming and walking in vertebrates are located in the lumbar spinal […]

Meeting Abstract S1.3  Tuesday, Jan. 4  Spinal Circuits That Generate Multiple Kinds of Rhythmic Limb Movements in Turtles BERKOWITZ, A.*; HAO, Z.-Z.; University of Oklahoma; University of Oklahoma ari@ou.edu Are different kinds of rhythmic limb movements that use the same muscles produced by separate or shared networks of CNS neurons? The turtle spinal cord is a model […]

Meeting Abstract S1.5  Tuesday, Jan. 4  Persistent inward currents in mouse spinal motoneurons: subcellular origins, postnatal development and neuropathology. QUINLAN, K.A.*; HECKMAN, C.J.; Northwestern University Feinberg School of Medicine; Northwestern University Feinberg School of Medicine katharina-quinlan@northwestern.edu Persistent inward currents (PICs) have been described in neurons from many experimental preparations, from adult turtle and cat to embryonic cultured […]

Meeting Abstract S1.4  Tuesday, Jan. 4  Passing Phases: Structure of a neural circuit that couples modular neural oscillators MULLONEY, B.*; SMARANDACHE, C.R.; Mulloney bcmulloney@ucdavis.edu Many behavioral tasks require synchronization of distributed neural circuits, but the neural mechanisms that synchronize them are largely unknown. In the crayfish CNS, the modular local circuits that control swimmerets are distributed in […]

Meeting Abstract S1.8  Tuesday, Jan. 4  Neuronal Control of Breathing: Rhythms within Rhythms, Networks within Networks. RAMIREZ, JM*; ZANELLA, S; GARCIA III, AJ; KOCH, H; DOI, A; University of Washington, Seattle; Seattle Children’s Research Institute, Seattle; Seattle Children’s Research Institute, Seattle; Seattle Children’s Research Institute, Seattle; Seattle Children’s Research Institute, Seattle nino1@uw.edu The neuronal control of breathing […]

Meeting Abstract S1.7  Tuesday, Jan. 4  Forty years of gastropod feeding: multiple buccal motor patterns but conservation of apparently homologous neuronal circuitry in rasping heterobranchs. RAMAKRISHNAN, S; YASHINA, I; MURPHY, A/D*; Univ. of Illinois at Chicago; Univ. of Illinois at Chicago; Univ. of Illinois at Chicago dmurphy@uic.edu Feeding in the snail, Helisoma, was originally described as a […]

Meeting Abstract S1.6  Tuesday, Jan. 4  Flexibility in the patterning and control of axial locomotor networks in lamprey BUCHANAN, J.T.; Marquette Univ james.buchanan@marquette.edu In lower vertebrates, locomotor burst generators for axial muscles generally produce unitary bursts that alternate between the two sides of the body. In lamprey, a lower vertebrate fish, locomotor activity in the axial ventral […]

Meeting Abstract S1.11  Tuesday, Jan. 4  Discussion

Meeting Abstract S1.1  Tuesday, Jan. 4  Coping with Variability in Small Neuronal Networks CALABRESE, Ronald L; Emory University ronald.calabrese@emory.edu The small neuronal networks that comprise invertebrate CPGs display a 2-5 fold range of intrinsic membrane currents and synaptic strengths across animals and yet produce functional output. In the leech heartbeat CPG, the patterned output of premotor interneurons […]

Meeting Abstract S1.2  Tuesday, Jan. 4  Brainstem neurons switch each other into pacemaker mode to drive movement by activating NMDARs LI, W.*; ROBERTS, A; SOFFE, S.R.; the University of St Andrews; the University of Bristol; the University of Bristol wl21@st-andrews.ac.uk Rhythmic activity is central to brain function. In the vertebrate central nervous system, the neuronal circuits for […]
