part of innervated by overlaps develops from part of adult antennal nerve antennal mechanosensory and motor center AMC antenno-mechanosensory center Adult neuropil domain that receives the axonal projections of the Johnston organ neurons (JONs) (Ito et al., 2014). It is part of the saddle, which is found in a relatively dorsal part of the subesophageal zone (Ito et al., 2014). It develops from the anteriormost (tritocerebral) part of the larval central sensory column, which greatly increases in size as JON axons enter it via the antennal nerve during metamorphosis (Kendroud et al., 2018). Afferents of the JONs also invade the mandibular and maxillary neuromeres (Kendroud et al., 2018). antennal mechanosensory region AMMC VFB:FBbt_00003982 FBbt:00003982 dorsal lobe fly_anatomy.ontology adult tritocerebrum adult maxillary neuromere adult mandibular neuromere saddle adult sensory region of subesophageal zone larval central sensory compartment adult central sensory compartment of subesophageal zone
