The layer GL is made of fibers having almost spherical shape (also called neuropil) where connections between axon terminals from olfactory nerve, dendrites from mitral cell and periglomerular (PG) cells are formed as dendro-dendritic synapses.
To isolate putative olfactory proteins from the navel orangeworm, we extracted proteins from olfactory and non-olfactory tissues dissected from adult males and females, and compared protein profiles of these extracts by native polyacrylamide gel electrophoresis (PAGE).
To this end an EST collection produced from a normalized cDNA library of the olfactory epithelium from sexually mature goldfish was analysed.
Homologs of the chemosensory GPCRs from nematodes, plant GPCRs, Yeast Pheromone receptors, gustatory and olfactory receptors from insects were not identified.
Our knowledge of the olfactory passage from a stimulus all the way to behavior has profited much from this species.
(There is also no shortage of jokes bemoaning the olfactory assault from the unwashed masses in the subways when the temperature sometimes reaches the 80s).
Since 1991, Dr. Axel and Dr. Buck have worked independently and "have in several elegant, often parallel, studies clarified the olfactory system, from the molecular level to the organization of the cells," the assembly said.
He likes to joke that the scar left by the operation to remove a part of the olfactory bulb from his forehead makes him look like Frankenstein, and his stiff walk, combined with his shaved head, accentuated the impression.
Smelling androstadienone has previously been shown to improve mood and increase sexual arousal in women, but this is the first time that an olfactory stimulus from a specific molecule has been found to lead to a change in hormone levels.
These microdialysis studies, however, did not thoroughly investigated if olfactory stimuli from estrous females could significantly increase the extracellular DA in the NAcc of male rats.
