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