Thesupraesophageal ganglion (also "supraoesophageal ganglion", "arthropod brain" or "microbrain"[1]) is the first part of thearthropod, especiallyinsect,central nervous system. It receives and processes information from the first, second, and thirdmetameres. The supraesophagealganglion 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.
