Figure 6. Projections fru^M SOG∩4-57 neurons likely receive gustatory and descending protocerebral inputs.

A) Sagittal views showing mSG∩4-57 neurons projections in the brain.. Gustatory inputs from the labellum, mouthparts innervate the anterior-medial SOG and the tritocerebrum. Inputs from the superior medial protocerebrum also innervate the tritocerebrum. Descending tracts from the mSG∩4-57 innervate prothoracic/metathoracic and mesothoracic/abdominal ganglia boundaries B). The mSG∩4-57, and possibly aSG∩4-57 neurons, function to regulate initiation of wing extension and copulatory behaviors. SMPR = superior medial protocerebrum, and CC = cervical connective. TC marks the tritocerebrum. The SOG is marked by a dashed blue line.
