“…With a one-or two-dimensional spatial continuum a richer variety of instabilities from the (homogeneous) background states is possible, for example stationary periodic patterns and spatiotemporally oscillations, see, e.g., Ermentrout and Cowan (1979a,b), Ermentrout and Cowan (1980a,b), Hutt et al (2003), Curtu and Ermentrout (2004), Hutt and Atay (2005), Hutt (2005, 2006), Wyller et al (2007) and reviews by Ermentrout (1998), Bressloff (2005, and Coombes (2005). In the context of models in one or more spatial dimensions the present instability in the zero-dimensional spatial model corresponds to an infinite-wavelength instability, contrasting with the finite-wavelength instabilities generating the periodic structures, see, e.g., Wyller et al (2007).…”
