Visualizing an Olfactory Sensory Map
We have developed a genetic approach to visualize axons from olfactory sensory neurons expressing a given odorant receptor, as they project to the olfactory bulb. Neurons expressing a specific receptor project to only two topographically fixed loci among the 1800 glomeruli in the mouse olfactory bulb. Our data provide direct support for a model in which a topographic map of receptor activation ...
متن کاملThe olfactory sensory map in Drosophila.
The fruit fly (Drosophila melanogaster) exhibits robust odor-evoked behaviors in response to cues from diverse host plants and pheromonal cues from other flies. Understanding how the adult olfactory system supports the perception of these odorous chemicals and translates them into appropriate attraction or avoidance behaviors is an important goal in contemporary sensory neuroscience. Recent adv...
متن کاملA Map of Olfactory Representations in the Drosophila Mushroom Bodies
Gene expression patterns are revealed by GFP reporter. Brains are counterstained with DiD, a fluorescent membrane probe penetrates readily into thick tissue to label all neuropil structures. Because of near infrared emission, DiD is excellent for multicolor labeling together with GFP expression. We routinely image DiD-labeled brains using a 40x C-Aprochromat water-immersion objective lens (N.A....
متن کاملA Map of Olfactory Representation in the Drosophila Mushroom Body
Neural coding for olfactory sensory stimuli has been mapped near completion in the Drosophila first-order center, but little is known in the higher brain centers. Here, we report that the antenna lobe (AL) spatial map is transformed further in the calyx of the mushroom body (MB), an essential olfactory associated learning center, by stereotypic connections with projection neurons (PNs). We foun...
متن کاملA Novel Approach to Surgical Markings Based on a Topographical Map and a Projected 3D Hologram.
Purpose: Surgical markings play a crucial role in planning plastic surgery procedures.[1, 2] Despite the importance of markings as a guide, these surgical markings are often imprecise. [3] Herein we describe a novel approach to lipostructure, guided by a computer-based roadmap. A digital 3D topographical surgical map is created using 3D photography and analytic software and then projected as an...
