Neural Circuit Recording from an Intact Cockroach Nervous System Josh S. Titlow1, Zana R. Majeed1,2, H. Bernard Hartman3, Ellen Burns1, Robin L. Cooper1 1Department of Biology, University of Kentucky, 2Department of Biology, University of Salahaddin, 3Oregon Institute of Marine Biology, University of Oregon This article describes the cockroach ventral nerve cord dissection and extracellular recordings from the cercal nerve and connectives. Evoked responses are generated by electrical stimulation of the cercal nerve or direct mechanical stimulation of the cerci.
Proprioception and Tension Receptors in Crab Limbs: Student Laboratory Exercises Zana R. Majeed1,2, Josh Titlow1,2, H. Bernard Hartman3, Robin Cooper1,2 1Department of Biology, University of Kentucky, 2Center of Muscle Biology, University of Kentucky, 3Oregon Institute of Marine Biology, University of Oregon Physiological and anatomical techniques are demonstrated to address function and structure for joint proprioceptors and muscle tension receptors in crustacean walking limbs.
Making Gynogenetic Diploid Zebrafish by Early Pressure Charline Walker1, Greg S. Walsh2, Cecilia Moens2 1Institute of Neuroscience, University of Oregon, 2Division of Basic Science, Fred Hutchinson Cancer Research Center - FHCRC This is a method for generating gynogenetic diploid zebrafish embryos (embryos whose only genetic contribution comes from the mother) by blocking the second meiotic division immediately after fertilization with ultraviolet light-inactivated sperm. EP embryos are not fully homozygous due to recombination during the first meiotic division, however they are homozygous at all loci that have not been separated from their centromere by recombination.
