The femoral chordotonal organ is located in the femur of the insect leg and it detects position, speed, acceleration, and vibration of the tibia relative to the femur. In Drosophila melanogaster, where it is possible to systematically analyze neuronal populations using genetic tools, the sensory neurons of the femoral chordotonal organ can be separated into at least 3 functionally and genetically distinct populations: the club, claw, and hook. The club neurons encode bi-direct… WitrynaJohnston’s organ is required for negative geotaxis in Drosophila.(A) Schematic showing the fly head, antenna, Johnston’s organ, and a single scolopidium of Johnston’s organ.
