Notes: x, present; −, not present; no annotation, not clear whether present or not (no statement is provided in papers). Acronyms: CB, central body; AL, antennal lobe; OL, optic lobe; LK, lateral horn; TC, tritocerebrum; SEZ subesophageal zone; DNs, descending neurons; LNC, lateral neurosecretory cells; MNC, median neurosecretory cells. 1 The majority of the LK cell bodies are in the protocerebrum and subesophageal zone (SEZ), but processes innervate neuropils in other brain regions. 2 In ALK neurons (LNCs), the LK expression is strong in larvae and weak and variable in adults. 3 The description of distribution of LK neurons and their processes is not detailed.
