About: The neural field equation τ du/dt = −u + ∫w(x−x')f(u(x'))dx' describes spatially continuous neural populations. With Mexican-hat coupling (local excitation, lateral inhibition), the field self-organizes into a stable localized "bump" of activity — a model of spatial working memory. The bump can be nudged to any location, persisting as an attractor.
