General Information
Term sound activated Johnston organ neuron ID (Ontology) FBbt:00100002 (Fly Anatomy)
Definition Johnston organ neuron (JON) that is activated by near-field sound ranging from 4 Hz to 952 Hz, maximally at 90dB (Kamikouchi et al., 2009; Yorozu et al., 2009; Patella and Wilson, 2018). These neurons are transiently (phasically) activated by the onset and offset of arista displacement. Cells preferentially activated by low-frequency vibration are loosely distributed as a ring in the middle layer of JON cell bodies. Higher frequencies preferentially activate JON neurons with cell bodies located mainly in the inner layer, directly surrounding the antennal nerve (Kamikouchi et al., 2006), and lateral axons (Patella and Wilson, 2018).[ FlyBase:FBrf0194812 FlyBase:FBrf0207518 FlyBase:FBrf0207559 FlyBase:FBrf0238696 ]
Also Known As"Johnston organ neuron phasically activated by arista deflection" ; "Johnston's organ neuron phasically activated by arista deflection" ; "sound activated Johnston's organ neuron" (for all, see Synonyms field below)
