Often the equations that describe how a passive membrane responds to a square-wave stimulus are given, with two major ideas missing: first, an intuitive explanation of the process of how current crosses the membrane, second, the relation of the RC circuit model to actual channels. This lab does not deal with cable theory or the spatial spread of voltage in axons and dendrites.\r\n\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Conductance; Passive properties; Resistance\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Neurobiology\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/95\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
