Evidence that EA bundle of AMMC lacks presynaptic sites is based on negative anti-syntaxin immunolabelling and synaptobrevin::GFP localization (Kamikouchi et al., 2006). Johnston organ neuron bundle EA EA JON-EA FBbt:00100006 VFB:FBbt_00100006 primary auditory center subarea EA Bundle, devoid of presynaptic sites, formed from one branch of the final, most posterior bifurcation of the antennal mechanosensory and motor center (AMMC) main trunk (MT). The other side of the bifurcation gives rise to the lateral core of the AMMC (LC). It is directly connected to zone E of the AMMC and consists of the projections of zone E Johnston's organ neurons.
