Neuropil mass below the esophagus in the adult brain. It encompasses the gnathal ganglion, the prow and the saddle.

This term refers to what used to be called subesophageal ganglion. The new name, together with supraesophageal zone, refer to the brain tissue below and above the esophagus and do not respect neuromere boundaries. The terms cerebral ganglia (CRG) and gnathal ganglia (GNG), denote the segmental neuromeres of the brain (the 3 rostral and 3 caudal, respectively) (Ito et al., 2014). Sterne et al. (2021) - FBrf0251280 define the SEZ as comprising GNG + TR.
