    J Morphol 257:212-8. 2003
    ..The oscillatory signal appears therefore to be relayed from one LPN pair to the next. Despite their evident importance in the anterior cord, the role these cells play more caudally in signal propagation is not clear...

    Thurston Lacalli
    Biology Department, University of Victoria, Cunningham Building, Victoria, BC, V8W 3N5, Canada
    Evodevo 3:12. 2012
    ..Among the latter is the possibility that a notochord may not have been needed as a primary stiffening device if other structures (for example, the dorsal organ) could perform that role...

    Thurston C Lacalli
    Biology Department, University of Victoria, BC, Canada
    Arthropod Struct Dev 38:361-75. 2009

    Thurston C Lacalli
    Biology Department, University of Victoria, Victoria, BC, Canada V8W 3N5
    Brain Res Bull 75:319-23. 2008

    Thurston C Lacalli
    Biology Department, University of Victoria, Victoria, B C, Canada, V8W 3N5
    Int J Biol Sci 2:104-9. 2006

    T C Lacalli
    Biology Department, University of Saskatchewan, Saskatoon, Canada
    Int J Dev Biol 44:903-6. 2000
    ..Among the neurons, the segmentally arranged DC (dorsal compartment) motoneurons appear to be among the first to develop, which accords with molecular data on the time course of neural development, using neurogenin and islet as markers...
