supraesophageal ganglion
(Order Amphipoda):
Concentration of nerve tissue above (anterior to) esophagus in head. Connected to subesophageal ganglion by pair of esophageal connectives. (Syn. brain) [Stachowitsch, 1992].
(Order Isopoda):
Concentration of nerve tissue above (anterior to) foregut. Connected to subesophageal ganglion by pair of esophageal connectives. (Syn. brain) [Stachowitsch, 1992].
(Subclass Branchiura):
Concentration of nerve tissue anterior (dorsal) to esophagus. A proto-, deutro- and tritocerebrum may be distinguished. Connected to subesophageal ganglion by pair of circumesophageal connectives. Innervates antennules and eyes [Stachowitsch, 1992].
(Class Ostracoda):
Concentration of nerve tissue anterior (dorsal) to esophagus. Connected to ventral nerve cord by pair of circumesophageal connectives. (Syn. brain) [Stachowitsch, 1992].
(Class Ostracoda):
Concentration of nerve tissue anterior to esophagus and innervating, among others, compound eyes. Fused with circumesophageal connective to form circumesophageal nerve ring. (Syn. brain) [Stachowitsch, 1992].
(Order Euphausiacea):
Concentration of nerve tissue in anterior region of cephalothorax; located above (anterior to) esophagus and somewhat anteroventral to stomach. Joined to chain of postoral ganglia by pair of esophageal connectives. (Syn. brain) [Stachowitsch, 1992].
