Role of a collision-sensitive neuron during collision avoidance in flight

Event Abstract Back to Event Role of a collision-sensitive neuron during collision avoidance in flight Raymond W. Chan1*, Fabrizio Gabbiani1, 2 and Reid Harrison3 1 Baylor College of Medicine, United States 2 Rice University, United States 3 Intan Technologies, LLC, United States The neural mechanisms underlying collision avoidance in flight are largely unknown territory. Using a custom designed telemetry chip we record from the DCMD (Descending Contralateral Movement Detector), a collision detecting neuron, and flight muscles of a locust (Schistocerca americana) flying in a wind tunnel. Simultaneously, two high-speed video cameras are used to record flight data of the locust while it performs collision avoidance manoeuvres in response to the simulated approach of an object on a collision course with the animal (i.e., a looming stimulus). Using custom built software, we reconstruct in 3D flight parameters like body orientation and wing height from the stereoscopic videos. Neural data is then correlated with behavioural data to shed light on the neural basis of this behaviour. In addition, we design a filter-based system using the muscle and neural signals to control a virtual drone.
