The researchers scrutinized the neuronal architecture of the olfactory glomeruli in the vinegar fly Drosophila melanogaster and linked the morphological differences they observed to the respective functions. They labeled different neurons in single glomeruli, and counted and anatomically described these.

Glomeruli have long been considered functional units in coding olfactory information (3, 5 - 8). Most or all of the ≈12,000 OSNs (3) converging onto a glomerulus express the same single odorant receptor from a repertoire of ≈1,000 genes (17 - 21).

Glomerulus function olfactory

Odor processing starts at the level of the olfactory glomerulus. Besides olfactory nerve terminals, the glomerulus is surrounded by hundreds of juxtaglomerular cells. The specific function of the glomerular structures present in the antennal lobes or olfactory bulbs of organisms ranging from insects to humans has been obscure because of limitations in neuronal marking methods. By tracing individual neurons in the moth Agrotis segetum, it was determined that physiologically distinct types of pheromone receptor neurons project axons to different regions of To further understand the organization and function of glomeruli, a comparative approach to structural, molecular and physiological properties of olfactory glomeruli is particularly promising, and should lead to the discovery of the most essential features of olfactory glomeruli. The glomerulus is an integral part of the nephron, the basic unit of the kidney. Each nephron is capable of forming urine by itself, and each kidney has approximately a million nephrons.

Olfaction, or the sense of smell, is the special sense through which smells (or odors) are perceived. It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. Olfaction has many functions, including detecting hazards, and pheromones, and plays a role in taste.

The olfactory system, or sense of smell, is the sensory system used for smelling ().Olfaction is one of the special senses, that have directly associated specific organs.. Most mammals and reptiles have a main olfactory system and an accessory olfactory syst Olfactory bulb is a bulb-shaped nervous tissue made up of multiple layers of cells. Histologically, it is divided into five layers. Here, we will discuss these layers individually.

Glomeruli in the olfactory bulb are anatomically discrete modules receiving input from idiotypic olfactory sensory neurons. To examine the functional organization of sensory inputs to individual glomeruli, we loaded olfactory sensory neurons with a Ca2+ indicator and measured odorant-evoked presynaptic Ca2+ signals within single glomeruli by using two-photon microscopy in anaesthetized mice.

It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. Olfaction has many functions, including detecting hazards, and pheromones, and plays a role in taste. Each zebrafish olfactory bulb contains ~ 140 glomeruli that are distinguishable based on size, location, neurochemistry and function. Here we examine the mitral cell innervation of differently sized glomeruli in adult zebrafish. Type 1 glomeruli had diameters of 80.9 ± 8.1 μm and were innervated by … Inputs from olfactory sensory neuron (OSN) axons expressing the same type of odorant receptor (OR) converge in the glomerulus of the main olfactory bulb. A key marker of mature OSNs is olfactory The olfactory bulb transmits smell information from the nose to the brain, and is thus necessary for a proper sense of smell. With this in mind, its potential functions can be placed into four general categories: • Enhancing discrimination between odors • Enhancing sensitivity of odor detection • Filtering out many background odors Each glomerulus is targeted by olfactory receptor neurons expressing a single type of olfactory receptor protein.

In 2002-11-01 The axons of olfactory receptor cells which express the same OR converge to form glomeruli in the olfactory bulb. Function. ORs, which are located on the membranes of the cilia have been classified as a complex type of ligand-gated metabotropic channels.
