Increased selectivity requires competition and nonlinear activation function in pyramidal cells.

Increased selectivity requires competition and nonlinear activation function in pyramidal cells.

<p><b>A)</b> Illustration of the circuit model. Light gray triangles denote excitatory pyramidal populations, circles denote inhibitory populations. Excitatory populations inhibit each other via local interneurons (dark gray) and receive additional inhibition from PV cells (red). T...
