The wiring diagram with synaptic resolution, which is unknown for any glomerular olfactory system, would enable the formulation of circuit function hypotheses to

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). The glomeruli act as the sites where synapses are formed between the axons of the dendritic cells, carrying the olfactory signals, and the dendrites of cells present in other layers of the olfactory Each glomerulus making up the MGC has a specific functional identity, initially processing information about one specific pheromone component. This indicates that, at least through the first stage 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 “The complete quantitative mapping of all olfactory sensory neurons linked together in each olfactory glomerulus helped us to create an extended morphological basis for a better understanding of the role and function these units in the olfactory system have,” co-author Amelie Baschwitz summarizes.

In fact, we actually have two of these bulbs, with one in each hemisphere of the brain. This lesson explores the structure and cells that make up the glomerulus, which play a central role in filtering the blood and forming the ultrafiltrate.
one of the small spheric territories in the olfactory bulb in which dendrites of mitral and tufted cells synapse with axons of olfactory receptor cells.

Physiol Behav 67: 269–276, 1999. The type of neuronal activity required for circuit development is a matter of significant debate. We addressed this issue by analyzing the topographic organization of the olfactory bulb in transgenic mice engineered to have very little afferent spontaneous activity due to the overexpression of the inwardly rectifying potassium channel Kir2.1 in the olfactory sensory neurons (Kir2.1 mice). Zinc is a trace element with a multitude of roles in biological systems including structural and cofactor functions for proteins. Although most zinc in the central nervous system (CNS) is protein bound, the CNS contains a pool of mobile zinc housed in synaptic vesicles within a subset of neurons.

olfactory glomerulus A neural network found in the olfactory bulb, formed by the dendrites of mitral cells intertwined with the axons of olfactory receptor cells.
olfactory glomerulus A neural network found in the olfactory bulb, formed by the dendrites of mitral cells intertwined with the axons of olfactory receptor cells. Glomeruli are uniquely identifiable, functional units of the AL and the first synaptic sites within the olfactory system. Glomeruli are composed of densely packed neurites of, and synapses among, ORCs, AL neurons, and centrifugal neurons and are surrounded by a sheath of glial cells. The functions of the olfactory bulb In the olfactory bulb, neurons make synaptic connections with the mitral cells in the glomerulus, a group of neurons in the olfactory bulb that have different activation patterns and help you identify different smells. Glomeruli have long been considered functional units in coding olfactory information (3, 5 - 8).
