Fig. 7From: Dynamical systems analysis of spike-adding mechanisms in transient burstsThe slow flow on S near the top fold F 3 . Vectors of the slow flow on S are shown together with the orbit segment from Figure 5c. The direction of flow on S is indicated by the arrows where hotter colours correspond to vectors with larger magnitudes. The folded focus is the black dot on F 3 with the uniformly repelling and attracting parts of F 3 coloured light and dark green, respectively. Panels (a) and (b) show the process from two opposite viewpoints, and panels (c) and (d) show corresponding close-up views near F 3 .Back to article page
