p302fig08.18 This theorem shows how far away (L), given a fixed Gaussian width, two flashes can be to generate a wave of apparent motion between them.<BR>||  G-wave properties (Grossberg 1977). Let flashes occur at positions i=0 and i=L.  Suppose that d[dt: x0] = -A*x0 + J0; d[dt: xL] = -A*xL + JL; Define G(w,t) ...; Theorem 1 max_w G(w,t) moves continuously through time from w=0 to w=L if and only if L <= 2*K.
