... patterns in the crab Cancer pagurus . AGR has a bipolar cell body in the stomatogastric ganglion; it was activated by tension increase in gastric mill powerstroke muscles. While two spike initiation zones accounted for its spontaneous activity, active membrane properties (sag potentials, spike frequency...

... patterns. Long-lasting augmentation of the excitatory junction potentials (EJPs)quickens and strengthens the muscle response to a given motor pattern. We used the muscle gm6 of the crab Cancer pagurus to study the functional consequences and temporal dynamics of facilitation and augmentation. This stomach...

...S. G. Webster ABSTRACT The effects of emersion stress upon circulating hyperglycaemic hormone (CHH) levels in the edible crab Cancer pagurus were investigated using a highly specific and sensitive radioimmunoassay, with an antiserum directed against HPLC-purified C. pagurus CHH. Emersion resulted...
