Cooper1 1Department of Biology, University of Kentucky, 2Department of Biology, College of Science, University of Salahaddin, Iraq, 3Department of Neurobiology and Cognitive Neuroscience, SISSA, Italy This article describes three nervous system preparations using leeches: intracellular recording from neurons in ventral ganglia, culturing neurons from ventral ganglia, and recording from a patch of innervated skin to map sensory fields. Neuroscience 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.
