LIF Neuron Network with STDP Plasticity (2D)

2D spiking-network lab: 40 excitatory + 10 inhibitory LIF neurons, a scrolling spike raster, a live membrane-voltage trace, and pairwise STDP that visibly strengthens or weakens excitatory synapses as you watch.

This 2D companion runs the same leaky-integrate-and-fire network and pairwise STDP rule as the 3D version through a plain canvas view built for reading the dynamics directly: a scrolling spike raster shows every excitatory and inhibitory neuron firing in real time, a voltage trace follows one sampled neuron up to threshold and reset, and a mean-weight trace tracks the recurrent excitatory synapses strengthening or weakening under STDP as you change the external drive, noise and coupling strength.
