Meeting Abstract S2.5  Tuesday, Jan. 4  Patterns of functional integration in the mammalian masticatory apparatus VINYARD, CJ*; DOHERTY, AH; WALL, CE; WILLIAMS, SH; ROSS, CF; HERRING, SW; CROMPTON, AW; HYLANDER, WL; NEOUCOM; NEOUCOM; Duke Univ; Ohio Univ; Univ of Chicago; Univ of Washington; Harvard Univ; Duke Univ cvinyard@neoucom.edu Jaw-muscle recruitment plays a key role in the complex […]

Meeting Abstract S2.6  Tuesday, Jan. 4  Masticatory motor patterns of herbivorous marsupials. CROMPTON, AW; WILLIAMS, SH*; Harvard Univ; Ohio Univ acrompton@oeb.harvard.edu Primitive masticatory motor patterns are characterized by the activation of a set of muscles (Group I) that move the working-side jaw laterally and vertically during occlusion followed by a comparable set (Group II) that move the […]

Meeting Abstract S2.9  Tuesday, Jan. 4  Mastication and the Postorbital Ligament: Dynamic Strain in Soft Tissues HERRING, S.W.*; RAFFERTY, K.L.; LIU, Z.J.; LEMME, M.; Univ. of Washington, Seattle herring@uw.edu Collagenous ligaments resist tension but are useless under other loading regimes. Whereas the periodontal and the jaw joint capsular ligaments are intrinsic parts of masticatory mechanics, this is […]

Meeting Abstract S2.2  Tuesday, Jan. 4  Mammalian Masticatory Muscles: homology, nomenclature, and diversification DRUZINSKY, R.E.*; DOHERTY, A.H.; DE VREE, F; Univ. of Illinois, Chicago; Northeast. Ohio Univ. Col. of Med. and Pharm.; Univ. of Antwerp, Belgium druzinsk@uic.edu There is a deep and rich literature of comparative studies of jaw muscles in mammals (e.g., Toldt,1905; Edgeworth, 1935; Turnbull, […]

Meeting Abstract S2.1  Tuesday, Jan. 4  Introduction: Overview of the Feeding Experiments End-User Database (FEED) WALL, C.E.**; VINYARD, C.J.; WILLIAMS, S.H.; GERMAN, R.Z.; GAPEYEV, V.; LIU, X.; Duke Univ.; NEOUCOM; Ohio Univ.; Johns Hopkins Univ.; NESCent; NESCent cw19@duke.edu In 2009, we initiated a Working Group of feeding physiologists supported by the National Evolutionary Synthesis Center to develop […]

Meeting Abstract S2.10  Tuesday, Jan. 4  Determinants of variance in 3-D jaw kinematics in two species of primates IRIARTE-DIAZ, J.*; REED, D.A.; ROSS, C.F.; University of Chicago; University of Chicago; University of Chicago jiriarte@uchicago.edu The mammalian feeding system presents practical advantages for the study of kinematics and its relationship to musculoskeletal morphology and neural and muscle activity. […]

Meeting Abstract S1.9  Tuesday, Jan. 4  The role of genetically-defined lamina VIII interneurons in generating the mammalian locomotor rhythm. GOSGNACH, Simon; University of Alberta, Edmonton AB gosgnach@ualberta.ca Locomotor activity in mammals is generated by neural networks known as central pattern generators (CPGs), which are comprised of spinal interneurons located in the lower thoracic and lumbar spinal cord. Recently, […]

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 […]
