 The club neurons encode bi-directional movements and vibrations of the tibia, the claw neurons encode position of the tibia, and the hook neurons encode directional movements of the tibia.Information encoded by the femoral chordotonal organ is thought to be used during behaviors that require precise control of leg movements, such as walking and target reaching.In the femoral chordotonal organ, the scolopidia are organized into groups called scoloparia.
