Thesupraesophageal ganglion (alsosupraoesophageal ganglion,arthropod brain, ormicrobrain[1]) generally consists of a set of three fused pairs ofganglia, which constitute thebrain in mostinsect species and in some other closely relatedarthropods, such asmyriapods andcrustaceans. It receives and processes information from the first, second, and thirdmetameres. The supraesophageal ganglion liesdorsal to theesophagus and consists of three parts, each a pair of ganglia that may be more or less pronounced, reduced, or fused depending on thegenus:
Thetritocerebrum integrates sensory inputs from the previous two pairs of ganglia.[2] The lobes of the tritocerebrum split to circumvent the esophagus and begin thesubesophageal ganglion.
