It has been known that the smaller subgroup sLNv send projections towards a number of neural circuits including, the dorsal lateral neurons (DN), mushroom bodies (MB) and pars intercerebralis (PI), which are the critical regulators of fly sleep/wake cycles (Pitman et al., 2006; Joiner et al., 2006).
Ultrastructural effects of the cerebral neurosecretory cells treated with lufenuron.--The part played by neurosecretory cells in the pars intercerebralis during moulting and metamorphosis is well known (Wigglesworth 1954) and in some insects these cells are also involved in ovarian development and oviposition (Thomsen 1952, Nayar 1958).
While some workers have dealt with ultrastructural effects on the neurosecretory cells in the pars intercerebralis region of the brain, this study is the first concerned with this point under the treatment of lufenuron.
