Regulation of life-long neurogenesis in the decapod crustacean brain.
This article provides an overview of our understanding of life-long neurogenesis in the decapod crustacean brain, where the proliferation of sensory and interneurons is controlled by many of the same factors as is neurogenesis in the mammalian brain. The relative simplicity, spatial organization and accessibility of the crustacean brain provide opportunities to examine specific neuronal pathway...
متن کاملCrustacean Parasites as Phylogenetic Indicators in Decapod Evolution
The evolutionary history of decapods and their parasites is assessed with particular reference to the use of parasites as proxies for host phylogeny. We focused on two groups of obligate parasites that use decapods as their definitive hosts: parasitic isopods of the family Bopyridae and,parasitic barnacles of the superorder RhizO$<ephala. Bopyrids and rhizocephalans differ in that the rhizoceph...
متن کاملImaging mass spectrometry of neuropeptides in decapod crustacean neuronal tissues.
Imaging mass spectrometry (IMS) of neuropeptides in crustacean neuronal tissues was performed on a MALDI-TOF/TOF instrument. Sample preparation protocols were developed for the sensitive detection of these highly complex endogenous signaling molecules. The neuromodulatory complements of the pericardial organ (PO) and brain of the Jonah crab, Cancer borealis, were mapped. Distributions of peptid...
متن کاملInsulin and gender: an insulin-like gene expressed exclusively in the androgenic gland of the male crayfish.
Members of the insulin family of hormones are generally not regarded as gender-specific, although there is sporadic evidence for the possible involvement of insulin pathways in sexual differentiation. In crustaceans, sexual differentiation is controlled by the androgenic gland (AG), an organ unique to males. To date, attempts to identify active AG factors in decapods through either classical pu...
متن کاملSex differentiation in goat fetus
Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. Since studies on sex differentiation in goat fetus are scarce, this study was performed. Twenty-five...
