Fig. 2.
The slowest time-scale (the inverse of the smallest eigenvalue) for various stimuli. For von Mises stimuli (solid line), the time scale increases exponentially with the number of inputs. This matches the simulation results extracted from Fig. 1 (circles). For triangular stimuli there is no such increase. Furthermore, for the triangular stimuli the eigenvalue corresponding to the highest Fourier-mode (dotted) is not necessarily the slowest eigenvalue (dashed). The simulations reflect this as well (triangles)
