... However, in order to achieve invariance with respect to x and µ in the central pattern neuron, we can make use of the subtraction of the peripheries. For any given ∆x this means that rper(x+µ+∆x) - rper(x+µ-∆x) = rdir(∆x). After differentiating this equation with respect to (x+µ) and rearranging we ...
