General Information
Term antennal mechanosensory and motor center zone A ID (Ontology) FBbt:00100015 (Fly Anatomy)
Definition Antennal mechanosensory and motor center zone A is a synapse rich sub-region of the antennal mechanosensory and motor center (AMMC) formed from bifurcation of the Johnston's organ bundle. (The other structure arising from this bifurcation is the main trunk of the AMMC (MT)). Zone A is rich in presynaptic sites of Johnston's organ neurons. The cell bodies of zone A Johnston organ neurons are located mainly in the inner layer of Johnston's organ, directly surrounding the antennal nerve (Kamikouchi et al., 2006).[ FlyBase:FBrf0194812 FlyBase:FBrf0207518 ]
Also Known As "AMMC zone A" ; "Johnston organ neuron bundle A" ; "JON bundle A"
Comment Presence of presynaptic sites of Johnston's organ neurons determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
