Before revision:  It consists of a discretization of a nonlinear reaction-diffusion equation (the Allen-Cahn equation), coupled with an ODE . Unlike many feedforward networks that are said to mimic brain or cortical cells functioning, the PSBC is inspired by fluid behavior, namely, on how binary fluids phase separate.
