It excludes the gnathal ganglion. Developmentally, it comprises three fused neuromeres: protocerebrum, deutocerebrum, and tritocerebrum. fly_anatomy.ontology This term is related to what used to be called supraesophageal ganglion, and is now referred to as supraesophageal zone. The adult cerebral ganglion, together with the gnathal ganglia (GNG), denote regions that follow the segmental neuromeres of the brain (the 3 rostral and 3 caudal, respectively). These are distinguishable from supra- and subesophageal zones, as these refer to the neuropil masses above and below the esophagus and do not respect neuromere boundaries (Ito et al., 2014). brain SPG cerebrum FBbt:00110636 UBERON:6110636 adult supraesophageal ganglion
