General Information
Term antennal mechanosensory and motor center ID (Ontology) FBbt:00003982 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0194812 FlyBase:FBrf0211016 FlyBase:FBrf0224194 FlyBase:FBrf0237251 ]
Also Known As"AMC" ; "AMMC" ; "antennal mechanosensory region" (for all, see Synonyms field below)
