In neurobiology the length constant is a mathematical constant used to quantifythe distance that a graded electric potential will travel along aneurite via passive electrical conduction The greater the value ofthe length constant the farther the potential will travel A largelength constant can contribute to spatial summationthe electricaladdition of one potential with potentials from adjacent areas ofthe cellThe length constant can be defined asdisplaystyle lambda sqrt fracrmrirowhere rm is the membrane resistance the force that impedes theflow of electric current from the outside of the membrane to theinside and vice versa ri is the axial resistance the force thatimpedes current flow through the axoplasm parallel to
