General Information
Term large DN3 neuron ID (Ontology) FBbt:00052275 (Fly Anatomy)
Definition DN3 neuron that has a relatively large cell body (Reinhard et al., 2022). It projects anteriorly to the anterior optic tubercle forming a characteristic loop around the superior lateral protocerebrum (Reinhard et al., 2022). Some of these cells form additional loops (Reinhard et al., 2022). It has a ventral projection that reaches the accessory medulla (Reinhard et al., 2022). There are four or five of these cells per hemisphere, half with relatively anterior somas and half with relatively posterior somas (Reinhard et al., 2022).[ FlyBase:FBrf0253505 ]
Comment Some seem to project contralaterally via the SAC, but not seen in any hemibrain large DN3s (Reinhard et al., 2022). All hemibrain cells have SLP loop, but other two loops described in Reinhard et al. (2022) are not consistent.
