The lab has several challenges where you set the membrane potential of the cell to different values by changing these two factors. \r\n\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Ion channels; Ions; Membrane potential\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Neurobiology\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/94\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
