... in transforming larval to adult tissue we have mapped the metamorphic changes in a particularly well established brain area, the antennal lobe of the sphinx moth Manduca sexta , using an antiserum recognizing RFamide-related neuropeptides. Five types of RFamide-immunoreactive (ir) neurons could be distinguished...

...Elsa G. Escamilla-Chimal; François Van Herp; María-Luisa Fanjul-Moles ABSTRACT The present study investigated changes in crustacean hyperglycaemic hormone (CHH) and serotonin (5-hydroxytryptamine, 5-HT) immunoreactivity in the retina and the X-organ/sinus gland complex (XO-SG) of the crayfish...

... ( Locusta -DH) and serotonin, we have mapped the distribution of neurones displaying these phenotypes in R. prolixus . Strong Locusta -DH-like immunoreactivity was found in numerous neurones of the central nervous system (CNS) and, in particular, in medial neurosecretory cells of the brain and in posterior...

...Toshiki Nagayama; Hitoshi Aonuma; Hiroki Miyata ABSTRACT Using an antiserum directed against γ-aminobutyric acid (GABA) to label neurones with GABA-like immunoreactivity, approximately 70 central neurones (68±9; mean ± S.E.M., N =9) were labelled in the terminal abdominal ganglion of the crayfish...

..., locustatachykinin-like, myomodulin-like, proctolin-like, red pigment concentrating hormone-like and serotonin-like immunoreactivities are all present in both the stomatogastric neuropil and at least one of the neurohemal organs. Thus, these substances are likely to serve a dual role as both local and hormonal...

...Richard A. Satterlie; Tigran P. Norekian; Sheryl Jordan; Charles J. Kazilek ABSTRACT Serotonin-immunoreactive somata in the pteropod mollusc Clione limacina were restricted to the cerebral and pedal ganglia. 10–14 pairs of cells were consistently found in the cerebral ganglia, including one large...
