Synapses in + out. CT1 and APL are single cells that touch almost everything in their region.
A browser can't draw 139,248 arbors, so 3,064 were chosen: the whole of several famous circuits plus a stratified sample of everything else. Toggle groups to draw them.
Each stimulus drives a real sensory population in a leaky integrate-and-fire model of this exact wiring (Shiu et al., Nature 2024), simulated for 300 ms. Play it back and watch the spikes travel.
Ten stops through the brain, from the eyes to the escape reflex. Each stop sets the camera, layers and colours for you.
