Here, inside the olfactory glomeruli, different groups of olfactory neurons form conjunctions or synapses which enable different environmental odors to be processed. Until now, scientists had assumed that olfactory glomeruli share a pretty homogeneous architecture and that particular functions of the different glomeruli can be attributed

Each glomerulus is targeted by olfactory receptor neurons expressing a single type of olfactory receptor protein. The glomerulus provides a unique model in which the function of a cortical module can be Olfactory glomeruli have unique architectures which already represent the ecological relevance of the odor they process. In order to link the morphology of a glomerulus to its function, 10.1055/b-0034-91130 Functional Anatomy of the Olfactory System II: Central Relays, Pathways, and their FunctionJessica Freiherr, Martin Wiesmann, Martin Witt Introduction The first steps of central olfactory processing are accomplished in phylogenetically old brain structures located in the basal forebrain and medial temporal lobe, which are activated simultaneously or consecutively. Request PDF | The Olfactory Glomerulus: A Model for Neuro-Glio-Vascular Biology | Brain imaging has had an enormous impact on our understanding of brain function, but the mechanisms that produce Olfactory glomeruli have long been hypothesized to play a critical role in odor coding. Only recently, however, has an integrated picture emerged of the molecular, anatomical, and functional relationship within and among olfactory glomeruli, the olfactory receptor neurons which project to them, and their representation of olfactory information. The olfactory bulb is a small vesicular structure whose main function is to capture and process information from odor receptors located in the nasal mucosa. In fact, we actually have two of these bulbs, with one in each hemisphere of the brain.

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 …

Odor processing starts at the level of the olfactory glomerulus. Besides olfactory nerve terminals, the glomerulus is surrounded by hundreds of juxtaglomerular cells.

2020-11-25 · This layer consists of spherical structures called glomeruli (singular glomerulus). It is the outer most layer of olfactory bulb and is the site of synapse formation. The glomeruli present in the glomerular layer of the olfactory bulb are actually spherical or globular structures made up of globular tangles of axons of olfactory neurons and the dendrites of other cells such as mitral cells, tufted cells.

Odorants evoked patterns of discrete Ca2 signals throughout the neuropil of a glomerulus. Across glomeruli, Ca2 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. 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 senses of smell and taste are often referred to together as the chemosensory system, because they both give the The Glomerulus is basically the particular conformation of capillaries inside the nephron which allow the kidney to perform excellent filtration process. Among the whole animal�s vertebrates are the individual group which has advanced kidneys, which are typically used to preserve water in terrestrial animals. We here review the architecture and function of OB glomeruli, the first neuronal microcircuit of the olfactory system.

To examine the functional organization of sensory inputs to individual glomeruli, we loaded olfactory sensory neurons with a Ca(2+) indicator and measured odorant-evoked presynaptic Ca(2+) signals within single glomeruli by using two-photon microscopy in anaesthetized mice. Here, inside the olfactory glomeruli, different groups of olfactory neurons form conjunctions or synapses which enable different environmental odors to be processed. Until now, scientists had assumed that olfactory glomeruli share a pretty homogeneous architecture and that particular functions of the different glomeruli can be attributed 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.
