%A Smith, Emily %A Titiz, Ali S. %A Walsh, Jennifer %D 2005 %T Carbon monoxide has varied effects on post-tetanic facilitation and depression in the crayfish neuromuscular junction %K %X We varied the concentration of CO in the crayfish neuromuscular junction (NMJ) to observe the effects of CO on excitatory post-synaptic potentials (EPSPs) and post-tetanic facilitation and depression. The decrease of CO in the crayfish NMJ had significant effects on post-tetanic EPSP amplitudes. Additionally, decreased CO increased post-tetanic facilitation immediately following stimulation, while increased levels of CO did not significantly affect post-tetanic facilitation except when combined with an NOS inhibitor. While we did not observe PTP as expected, we observed posttetanic facilitation and depression in the crayfish NMJ. %U https://ojs.grinnell.edu/index.php/pnsj/article/view/140 %J Pioneering Neuroscience %0 Journal Article %P 69-71%V 6 %8 2005-05-17
