Supraesophageal ganglion

The supraesophageal ganglion ("arthropod brain" or "a. microbrain"[1]) is the first part of the arthropod and especially insect central nervous system. It receives and processes information from the first, second, and third metameres. The supraesophageal ganglion lies dorsal to the esophagus and consists of three parts, each a pair of ganglia that may be more or less pronounced, reduced, or fused depending on the genus (biology):

Supraesophageal ganglion(5), Subesophageal ganglion(31)

The subesophageal ganglion continues the nervous system and lies ventral to the esophagus. Finally, the segmental ganglia of the ventral nerve cord are found in each body segment as a fused ganglion and they provide the segments with some autonomous control.
