circuits/Small object tracking

Figure-ground separation done with almost no machinery: a cell type that fires for small objects and is actively silenced by whole-field motion.

**Computes** Selects a small moving target against a moving background and reports its bearing. **Behaviour** Pursuit and body-size discrimination. **Timescale** Fast **Pathway** LC11 -> Central brain targets -> Steering descending neurons

Stages: - LC11 (input, lobula) — Small moving object, suppressed by wide-field motion - Central brain targets (relay, ventrolateral-neuropils) — Bearing extraction - Steering descending neurons (output, lateral-accessory-lobe) — Turn toward the target

The pathway is published anatomy and ships here. The connectivity behind it comes from the source dataset: import a brain to extract the actual neurons and weights.

- The wide-field suppression is a lateral inhibition motif.
