JON fly_anatomy.ontology Scolopidial (mechanosensory) neuron of Johnston's organ (JO). Its axon innervates the ipsilateral antennal mechanosensory and motor center (AMMC). A small number of fibers also innervate the contralateral AMMC via the commissure of JON. Subset of JO neurons extend into the ventral region of the ventrolateral protocerebrum and posterior part of the subesophageal ganglion. They are cholinergic and a subset are glutamatergic (Ishikawa et al., 2017). FBbt:00100000 JON Johnston organ bundle of antennal nerve
