What is this?

The animation behind this page is a live simulation of 1,000 neurons arranged as a population raster plot — each row is a neuron, each dot is a spike, and time runs right to left.

Each neuron has a preferred direction. Move your cursor and the neurons whose tuning matches the direction of motion fire more than the rest.

Click and hold anywhere to trigger a Reverberating Super Burst — a coordinated wave of activity that ripples across the population. RSBs show up in cultures of stem-cell-derived neurons during early development, and are hypothesized to strengthen network connections as neurons wire together.

As you click around and hold to produce RSBs, the network's propensity for spontaneous network bursts increases.

The strip at the bottom is the summed population firing rate — a rough stand-in for a local field potential (LFP). Watch it spike when an RSB fires.
