Intercerebral region (English spelling) pars intercerebralis

Japanese: 脳間部 - のうかんぶ(英語表記)pars intercerebralis
Intercerebral region (English spelling) pars intercerebralis
The insect brain (supraesophageal ganglion) consists of two hemispheres, divided into anterior, middle, and posterior cerebrum. The dorsal anterior part of the protocerebrum is called the intercerebral pars intermedius. The ophthalmic nerves emerge from here, and a large number of neurosecretory cells are distributed there. Those close to the midline are called medial neurosecretory cells, and those close to the anterior edge of the protocerebrum are called lateral neurosecretory cells (NC). In the cecropia pupa, there are 6 types of cells, 4 types in the center and 2 types on the sides, for a total of 36 cells, and in Orthoptera, the number reaches several hundred.
