New spiking neuron model exhibits soliton-like wave behavior

By PulseAugur Editorial · [1 sources] ·

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

IMPACT This research provides a foundational model for understanding complex neural dynamics, potentially informing future neuromorphic computing architectures.

    Soliton-like Waves in a Two-Dimensional Recurrent Spiking Neural Network with Weighted Spike-Timing-Dependent Plasticity

    We construct a minimal but biologically plausible spiking neuron model operating in discrete time, combining multiplicative spike-timing-dependent plasticity (WSTDP), divisive normalization of synaptic integration, homeostatic threshold adaptation, and a one-step refractory perio…
