Neurosecretory cells in Diptera.
The neurosecretory cells were studied in 20 dipteran species belonging to three suborders. The NSC are localized in (a) the frontal ganglion (in 10 of the 20 species studied), (b) the pars intercerebralis region of the protocerebrum (in the median and lateral groups), (c) the tritocerebral region of the brain (in 8 of the 20 species studied) and (d) the suboesophageal ganglion. In one species, NSC were also seen in the prothoracic ganglion. The NSC were classified as types A, B and C/D. The NSC of the median group of the pars intercerebralis were unusually large compared with the size of the brain. The number, size and distribution of the cells are discussed.
