You examine how the cell membrane potential (Vrest) behaves when the membrane is selective for K+,  for Na+ or has a mixed permeability to these ions. \x26quot;Ohmic\x26quot; channels are modeled as resistors therefore the conductance of channels to ions is independent of the concentration of the ions, and the current through the channel is the product of the conductance and the driving force. This laboratory involves as much thinking and graphing as it does experimentation.\r\n\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Ohmic equations; Resting potential\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Neurobiology\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/82\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
