circuits/Looming escape · giant fibre

The canonical escape reflex: two looming-sensitive populations converge on a single descending neuron that fires once and commits the animal to a jump.

**Computes** Time-to-collision from visual expansion, thresholded into a go/no-go escape decision. **Behaviour** Short-latency take-off. The fastest escape the fly has. **Timescale** Reflex **Pathway** LC4 -> LPLC2 -> Giant fibre (DNp01) -> TTMn / PSI
