Researchers have developed a minimal, biologically plausible spiking neuron model that incorporates weighted spike-timing-dependent plasticity (WSTDP), divisive normalization, and homeostatic adaptation. When arranged in a two-dimensional recurrent network, these neurons exhibit stable, self-propagating wave packets with properties similar to dissipative solitons. These waves maintain their form, travel at a constant speed, and annihilate upon collision, with WSTDP encoding the direction of propagation. This framework offers a simplified model for understanding the emergence of cortical traveling waves, activity zone delimitation, and spatial memory from local plasticity rules. AI
