The supraesophageal glanglia or brain of many invertebrates.

Examples

“We have⟳ then, probably, three types of syncerebra and two types of archicerebra among existing Crustacea.”

“The syncerebrum of the Tetradecapoda (Amphipoda and Isopoda), judging by Leydig's figures¹ and our own⟳ observations (from dissections made by Mr. J. S. Kingsley) on that of Idotæa and Serolis², is built on a different plan⟳ from that of the Decapoda.”

“In our Monograph of N. A. Phyllopoda, p.403, we adopted the view⟳ that the brains of all Crustacea except the Phyllopoda and Merostomata were syncerebra, and we divided the syncerebrum into three types; adding that the syncerebrum of sessile eyed crustacea (Edriophthalma) was built on a different plan⟳ from that of the Decapoda.”

“The brain is a syncerebrum which is composed of a protocerebrum, innervating the three parts of the eye and the frontal glands; a deutocerebrum, innervating the antennules; and a tritocerebrum which innervates the labrum and the antennae and which contains the tritocerebral gland.”

“The nervous system of Arachnida consists of a syncerebrum and the ventral ganglia that are more or less variously fused in a subesophageal nervous mass.”
