sends synaptic output to region auditory sensory neuron Johnston organ neuron zone A Johnston organ neuron 2009-12-07T12:53:56Z JO-A zone A Johnston's organ neuron FBbt:00100008 zone A JON 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).
