This contains numerous spheroidal reticulated enlargements, termed glomeruli, produced by the branching and arborization of the processes of the olfactory nerve fibres with the descending dendrites of the mitral cells. ❋ Unknown (1918)
The “particles,” I explained, were the protein in her urine, which had been allowed to flow through her damaged glomeruli, the little filtration units in every nephron of the kidney. ❋ MD Julian Seifter (2010)
Exceptions are membranes of capillaries and kidney glomeruli that have relatively large pores (about 40Å) that allow molecules up to a molecular weight of about 50,000 (molecules slightly smaller than albumen which has a molecular weight of 60,000) to pass through. ❋ Unknown (2008)
In the bulb, the axons of olfactory sensory neurons synapse in about 2,000 spherical structures, called glomeruli. ❋ Unknown (2005)
Different OR probes labeled different glomeruli and those glomeruli had virtually identical locations in different individuals. ❋ Unknown (2005)
As I discussed in my Nobel Lecture, the segregation of OR inputs in different glomeruli and neurons in the bulb gives way in the cortex to a complex array of OR inputs in which signals from different ORs partially overlap and single cortical neurons appear to receive signals from combinations of different ORs. ❋ Unknown (2005)
Kerry how many sections separated different labeled glomeruli in different bulbs. ❋ Unknown (2005)
Remarkably, Bob Vassar in Richard Axel's lab had concurrently found that different OR probes labeled different glomeruli in the rat bulb. ❋ Unknown (2005)
These studies indicated that while thousands of neurons expressing the same OR are highly dispersed in the epithelium, their axons all converge in a few specific olfactory bulb glomeruli. ❋ Unknown (2005)
The result is a stereotyped map of OR inputs in which signals derived from different ORs are segregated in different glomeruli and in the bulb projection neurons whose dendrites innervate those glomeruli. ❋ Unknown (2005)
Using probes that recognized single OR genes rather than subfamilies of related OR genes, we found that each probe labeled OR mRNAs in sensory axons that were confined to one or a few glomeruli at only two sites, one on either side of the bulb. ❋ Unknown (2005)
In the glomeruli we find not only the nerve processes from the olfactory receptor cells but also their contacts with the next level of nerve cells, the mitral cells. ❋ Unknown (2004)
The cells send thin nerve processes directly to distinct micro domains, glomeruli, in the olfactory bulb, the primary olfactory area of the brain. ❋ Unknown (2004)
The olfactory receptor cell sends its nerve processes to the olfactory bulb, where there are some 2,000 well-defined microregions, glomeruli. ❋ Unknown (2004)
The convergence of information from cells with the same receptor into the same glomerulus demonstrated that also glomeruli exhibit remarkable specificity (see figure). ❋ Unknown (2004)
There are thus about twice as many glomeruli as the types of olfactory receptor cells. ❋ Unknown (2004)
From the glomeruli, primary urine is passed on through a winding tube where about 70% of the water is reabsorbed to the blood by the aquaporin AQP1. ❋ Unknown (2003)
In its windings (termed glomeruli), which function as a sieve, water, ions and other small molecules leave the blood as ❋ Unknown (2003)
Joanna focused in on the glomeruli, the small cluster of capillaries through which the blood is filtered. ❋ Goldberg, Leonard (2001)
Along this line of research, Marilyn Farquhar and I investigated the capillaries of the renal glomeruli and recognized that, in their case, the basement membrane is the filtration barrier for molecules of 100A diameter or larger; a byproduct of this work was the definition of junctional complexes in a variety of epithelia. ❋ Unknown (1975)
