Figure 6. FMRFamide-like immunoreactivity (FLI) in the brain of Tabanus nigrovittatus. A) Anterior view of the brain showing FLI throughout the regions of the brain, including cells in the protocerebrum, pars intercerebralis (PI), optic lobes (OL) and the subesophageal ganglion (SOG). B) Posterior view of the brain showing FLI in cells of the protocerebrum and in nerve processes running down the cervical connective (CN). At least some cervical connective processes originate from cells in the subesophageal ganglion.
