Chordotonal organ

[4] The word was coined by Vitus Graber in 1882, though he interpreted them as being stretched between two points like a string, sensing vibrations through resonance.

[2] Mechanically gated ion channels are located distal to the ciliary dilation, a characteristic part of the upper dendritic cilium.

[2] One way to generate these functional diversity is by having sensory neurons with different types of mechanosensory channels or intrinsic properties.

For example, in Johnston's organ of Drosophila melanogaster, sensory neurons that detect sound may express nompC, an ion channel that belongs to the transient receptor potential (TRP) superfamily, while those that detect gravity may express another member of the TRP channel, painless.

[8] Another way to generate functional diversity is by having sensory neurons that are attached to the joint through different types of connections.

[14] Information encoded by the femoral chordotonal organ is thought to be used during behaviors that require precise control of leg movements, such as walking [15] and target reaching.

[2] In Drosophila melanogaster, in most mosquito species and some midge species, different subsets of Johnston's organ neurons are tuned to different amplitude and frequency of the movements allowing them to detect various stimuli including, sound, wind, gravity, wing beats, and touch.

It is located in the proximal part of the tibia and detects high-frequency acoustic vibrations transmitted through the substrate as well as sound through air.

They can be found in a variety of locations on the body, including the abdomen, wing base, metathorax, and ventral prosternum.

In lacewings, a tympanal organ is located in the radius vein of the forewing and is thought to monitor ultrasound.

[2] In the order Decapoda, there are chordotonal organs located in the legs, antennules, antenna, chelipeds, and mandibles.
