... in identified projection neurons to the STG. We describe the pattern of γ -aminobutyric acid (GABA) immunoreactivity in the stomatogastric nervous system of the crab Cancer borealis and demonstrate biochemically the presence of authentic GABA in C. borealis . No STG somata show GABA immunoreactivity but, within...

...Juan Carlos Jorge-Rivera; Eve Marder ABSTRACT The effects of insect allatostatins (ASTs) 1–4 were studied on the stomach musculature of the crab Cancer borealis . Of these, Diploptera-allatostatin 3 (D-AST-3) was the most effective. D-AST-3 (10 −6 mol l −1 ) reduced the amplitude of nerve-evoked...

...Andrew E. Christie; C. Tomas Lundquist; Dick R. Nässel; Michael P. Nusbaum ABSTRACT Immunocytochemical and biochemical studies have indicated the presence of many neuroactive substances in the stomatogastric nervous system (STNS) of the crab Cancer borealis . In electrophysiological studies, many...

...Regina M. Glowik; Jorge Golowasch; Rainer Keller; Eve Marder ABSTRACT We studied the effects of glucose on cultured X-organ neurons of the crab Cancer borealis using single-electrode current- and voltage-clamp techniques. A subpopulation of the cells responded to D-glucose with a hyperpolarization...

...Andrew E. Christie; Petra Skiebe; Eve Marder ABSTRACT The crustacean stomatogastric ganglion, which is situated in the ophthalmic artery, can be modulated by both intrinsically released molecules and hormones. In the crab Cancer borealis , over a dozen neuroactive compounds have been identified...

...Andrew E. Christie; David Baldwin; Gina Turrigiano; Katherine Graubard; Eve Marder ABSTRACT Three anti-cholecystokinin antibodies were used to label the stomatogastric nervous system of the crab Cancer borealis . Labeled tissues were examined as whole mounts using laser scanning confocal microscopy...

...Petra Skiebe; Henning Schneider ABSTRACT The effects of four Diploptera punctata allatostatin peptides on the stomatogastric nervous system of the crab Cancer borealis were studied. All of the peptides had similar actions on the activity of neurons involved in rhythmic movements of the pyloric...
