You are on an expedition to study neurons from tubeworms that live near deep sea hydrothermal vents. \x3cb\x3eYou should do Part I, Vent Worm Resting Potential lab, before doing this lab. \x3c/b\x3e\r\nYou review ionic substitution techniques as you determine the ionic basis of the action potential produced by shallow water tubeworm neurons (a typical Na/K dependent action potential).\r\nUsing these same techniques, you determine the ionic basis of the vent worm neuron action potential. You are challenged to determine the action of several novel toxins on the action potential generated by vent worm neurons.\r\n\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Action potentials; Ions\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Neurobiology\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/100\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
