∂u/∂t = −u + ∫ w(x−x′) f(u(x′)) dx′ + h. Mexican-hat connectivity w(x) creates localized activity bumps — the neural correlate of spatial working memory. Click to place a bump.
Click on canvas to inject a stimulus. Bumps act as attractor states for spatial working memory. Adjust inhibition range to shift between bumps, traveling waves, and oscillations.
