posterior maxillary sensory center

ID: FBbt_00040056

Region spanning the adult tritocerebrum and mandibular neuromere that contains terminals of sensory neurons that enter the brain via the anterior intermediate root of the maxillary-labial nerve and the anterior and medial roots of the pharyngeal nerve (Miyazaki and Ito, 2010. Five distinct subregions can be identified: a horn-like protrusion in the dorsolateral GNG (PMS1), a dorsal medial region (PMS2), a ventral medial region (PMS3), a zone near the entry point of the labial nerve (PMS4) and a zone ventral to PSM3 (PSM5) (Miyazaki and Ito, 2010. It arises from the larval anterior central sensory compartment (Kendroud et al., 2018. (Kendroud et al., 2018, Ito et al., 2014)

Bitter-sensitive neurons of the labellum sensilla (identified with Gr32a-, Gr66a- and NV4-GAL4) terminate in PMS1-3 zones. Subsets of Gr66a-GAL4 positive neurons terminated in specific subareas of these zones. Water-sensitive neurons (identified with NP1017-GAL4) and sugar-sensitive neurons (identified with Gr5a-GAL4) terminate in PMS4-5 zones (Miyazaki and Ito, 2010.
