Understanding How Dragonflies Target Their Prey
00:00 - 07:29 (07:29)
Dragonflies perform a rapid coordinate transformation to intercept their prey, going from their eye's frame of reference to the body's frame of reference in just 50 milliseconds. Researchers are studying the neural circuit responsible for this behavior, which can have at most four layers of neurons.

Dragon flies must perform a coordinate transformation to catch their prey, translating what they see into how their body needs to move to intercept.

Summary
Dragon flies must perform a coordinate transformation to catch their prey, translating what they see into how their body needs to move to intercept. They have a short response time (around 50 milliseconds) which allows them to complete around four layers of computational steps to calculate the direction they need to turn.

Summary
Researchers are studying the neural circuitry of dragonflies to understand how they perform coordinate transformations. By testing predicted neural responses with responses of neurons recorded in living dragonfly brains while they watch movies of moving targets, they hope to understand how dragonflies do coordinate transformations in one layer of neurons.
