SENN nerve stimulation source code is available free of cost or copyright restrictions: We are sharing the source code for a model that simulates nerve impulse (action potential) generation from electrical stimulation. The theory and software were devised by J. Patrick Reilly and Alan Diamant, two OSEL research fellows. The public release is of the source code, executables and users guide of their "Spatially Extended Nonlinear Node" (SENN) model. The applications for electrical stimulation device and associated software are broad and important. The software provides an intuitively simple model for estimating electrical dose at the site of nerve or muscle excitation. Their method, now available to the public, is value to both reviewers and researchers. Electrical dosimetry for electrical stimulation devices is evaluated by our staff, typically, on a case-by-case basis. The SENN model is universally applicable and provides an estimate for effective electrical stimulation without excessive stimulation. The book describes the "Threshold Factor" using the SENN neuro-electric model to give a numerical rating of any form of electrical stimulation. The "Threshold Factor" correlates with the volume of tissue containing neurons that may be excited by an electrical stimulus. The model and book unify our understanding of electrical dose. A large number of medical devices employ electrical stimulation of the spinal cord, deep brain, cerebral cortex, peripheral nerve, and auditory nerve, cardiac pacemakers, electrical defibrillators, muscle stimulators and magnetic stimulators. The earliest application of the SENN model was used to set MRI safety limits for induced electrical stimulation. Now this useful model has been converted to one that can be used on a personal computer (PC or Mac).
