In this study, we quantitate the impact of whole brain irradiation on the SVZ compartment and olfactory neurogenesis, as well as on the oligodendrocyte progenitors and mature myelin.
Due to the modular organization of the antenna, with compartments of a size varying between 5 and 12 annuli, and to the repetitive pattern of olfactory sensilla between the compartments, we did not need to map labeling of neurons along the whole antenna.
In Drosophila, OSNs expressing the same receptors connect with PNs in one of roughly 50 spherical compartments, termed olfactory glomeruli, which constitute a deutocerebral neuropil called the antennal lobe.
Olfactory glomeruli are morphologically conserved spherical compartments of the olfactory system, distinguishable solely by their chemosensory repertoire, anatomical position, and volume.
Examples of both cutting planes and stained sections covering a selection of CSF compartments from cerebellar to olfactory bulb subarachnoid spaces are shown in Figure 2.
Between each training session, both compartments were cleaned to remove olfactory cues.
Males in the side compartments could potentially detect visual and olfactory cues and fertilize eggs through the mesh but could not physically interact with each other or the female in the central compartment.
The ability of recognizing and discriminating thousands of odorant molecules in insects as in mammals relies on specialized chemosensitive neural cells expressing olfactory receptor proteins (ORs) which reside within segregated compartments called sensilla.
Furthermore, each PN type innervates a different compartment of the mushroom body, providing the means for encoding spatial olfactory information along the olfactory circuit.
First, it is organized into discrete compartments termed glomeruli as in the vertebrate olfactory bulb (Fig. 1 (A)) [5], [6].
