part of develops into nodulus primordium embryonic/larval nodulus - primordial 2018-02-15T14:21:50Z A small primordium in the larval brain that will give rise to the adult noduli. It appears as a ventrally directed process of the lateral primordial fan-shaped body. It is demarcated from the surrounding medial clamp and crepine by different the different concentration of synapses (e.g. as assayed by Bruchpilot expression). It develops from elements of the DPMm1, DPMpm1/2 and CM4 lineages. larvalbrain_neuropil:577 fly_anatomy.ontology larvalbrain_neuropil:399 VFB:FBbt_00007722 FBbt:00007722 primordium of noduli prNO embryonic/larval posterior lateral protocerebrum synaptic neuropil domain
