In Drosophila, a parasitoid wasp’s elongated antennae are detected and combined by lobula columnar neurons to drive directed defensive actions based on wasp position.
- Why it matters: Object recognition must link identity to the right action in context, but the neural circuit logic for predator-specific visual recognition and defense is unclear.
- What they did: Flies’ directed defenses were mapped to wasp position in view, and a neural circuit was defined using visual cue detection, LC neuron activation, and pathway relay to descending premotor targets.
- The result: Three LC types selectively respond to antennae and converge on LC9, which sums antennal and body-feature signals; spatial filtering of this composite representation drives location-specific defense.
