Grouped activity. Positions are schematic; lines show retained connections between groups.
Activity over time
Filtered firing rates · up to 250 samples · each sample follows 20 simulated milliseconds. Display speed depends on your device.
Application output
No output yet
This lamp maps the largest output intensity to brightness. It is an application effect, not biological movement.

Inspect a cell
Load a model to inspect its state.
Try a causal comparison
- Load the real circuit. Select
looming_left, apply a 100 ms stimulus, then run. Observe the GF group and output. - Reset, silence “All output neurons”, and repeat the same stimulus. Input populations can respond while new GF spikes are suppressed.
- Export the recording to reproduce the run in Python, or download a standalone HTML demo and edit its marked input/output section.
Recorded inputs are artificial current drives; this page does not simulate retinal images, natural escape behavior or learning. Read the source, assumptions and model card.
