Sentences with phrase «from olfactory neurons»

The neurons send their signals to the brain's olfactory bulb, where each of thousands of little clusters of neurons called glomeruli receives input from olfactory neurons with just one receptor type.

Not exact matches

Another risk stems from the fact that our olfactory receptor neurons dangle down into our nostrils, leaving them exposed to damage from environmental toxins and infections.

By tapping existing compounds known to block one class of olfactory neurons, scientists might be able to better camouflage humans from mosquito detection or draw mosquitoes away from humans with chemical bait.

Toxicants like solvents, pesticides or volatile molecules from oil spills can travel straight into the brain via the olfactory receptors — nasal neurons that number in the many millions, thickly studding the inner lining of the nose.

The virus appears to invade the brain by infecting a type of glial cell called olfactory ensheathing cells (OECs), which nourish smell - sensing neurons and guide them from the olfactory bulb to their targets in the nervous system.

This visual abstract depicts the discovery that chemosensory receptors in a subset of mammalian olfactory sensing neurons are structurally distinct from GPCRs, and multiple subtypes are expressed per neuron, implying an unexpected mechanism for olfactory detection and decoding.

Now, using a novel PET radiotracer called Neuroflux, a team of researchers from the Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) and the MassGeneral Institute of Neurodegenerative Disease has found a way to quantify olfactory sensory neurons and thus improve measurements of olfactory health.

Kenyon cells make up only about 4 % of the entire fly brain and are extremely sensitive to inputs triggered by odors, in which only two connections between neurons, called synapses, separate them from the receptor cells at the «front end» of the olfactory system.

Research conducted by Dr Bill Dew at the University of Lethbridge in Canada looked for the first time at the effect of the metal contaminants nickel and copper on specific fish olfactory sensory neurons, and how these affect the fish's ability to detect and swim away from an odour released by other fish of the same species (conspecifics) when a predator attack takes place.

Paying attention to the fact that each olfactory sensory neuron (OSN) expresses an OR, Shun «ichi Kuroda, Professor and Nobuo Yoshimoto, Specially Appointed Associate Professor at the Department of Biomolecular Science and Reaction, The Institute of Scientific and Industrial Research, Osaka University in cooperation with Masato Suzuki, Chief Researcher, Advanced Research Division, Panasonic Corporation made a system in which OSNs from mice were applied to a microchamber array on a microscope slide and fluorescence was yielded when ORs responded to odorants.

The team was able to view the responses of tens of neurons at a time to signals arriving in the olfactory bulb from the mouse's odor detectors, called olfactory sensory neurons, located in the nose.

They then tracked neurons as they migrated from region to region of the brain and found that new neurons oriented in the direction of fluid flow rather than the direction of their ultimate destination in the olfactory bulb.

Each odor - detecting neuron (referred to as olfactory sensory neuron from here on), chooses a single odorant receptor gene from a fairly large number of options that are split into class I (fish - like) and class II (terrestrial - specific) odorant receptors.

The benefits of using olfactory receptor neuron samples to study psychiatric disorders and patient responsiveness include their similarity to brain neurons, the relatively easy biopsy procedure, and the potential for scientists to sample and compare cells from the same patients throughout several different stages of disease.

In rats, olfactory bulb neurons use simple «linear summation'to make sense of fluctuating odor inputs from the surrounding environment...

The mouse olfactory sensory neuron (OSN) repertoire is composed of 10 million cells and each expresses one olfactory receptor (OR) gene from a pool of over 1000.
