JO-A [FBbt_00100008]
Johnston organ neuron (JON) that innervates zone A of the antennal mechanosensory and motor center (AMMC). The cell bodies of these neurons are located mainly in the inner layer of the Johnston organ, directly surrounding the antennal nerve (Kamikouchi et al., 2006; Ishikawa et al., 2017). These neurons respond to vibrations and are activated when stimulated with courtship pulse song, with greater activation at higher frequency (Kamikouchi et al., 2009).
