Smell

Smell is the sense that is concerned with the odor of things. It is perceived by receptors in the olfactory apparatus in the roof of ones nose. Signals here are transmitted along the Olfactory Nerve...

Olfactory glomeruli have a unique structure

Scientists have quantified and mapped the functional units of the olfactory center in the brains of vinegar flies responsible for the perception of odors. The basic units of the olfactory system in th...

The basic units of the olfactory system in the fly brain provide references to their function and ecological relevance

Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now quantified and mapped the functional units of the olfactory center in the brains of vinegar flies responsible for...

Novel radiotracer measures olfactory neurons in animal models

(Massachusetts General Hospital) Olfactory health - how well we are able to smell -- is a reliable marker of the health of the brain, but current 'smell identification tests' do not offer a complete p...

Pathway linked to slower aging also fuels brain cancer

While a particular metabolic pathway shows potential to slow down the aging process, new research indicates a downside: That same pathway may drive brain cancer.

When neurons are 'born' impacts olfactory behavior in mice

New research from North Carolina State University shows that neurons generated at different life stages in mice can impact aspects of their olfactory sense and behavior. The work could have implicatio...

New PET imaging technique may help monitor neurological disease progression

Olfactory neurons in the nasal cavity are the primary source of our sense of smell. Unlike many types of neurons, olfactory neurons are continuously generated throughout the adult lifespan. This uniqu...

New role of adenosine in the regulation of REM sleep discovered

The regulation and function of sleep is one of the biggest black boxes of today's brain science. A new paper published online on August 2 in the journal Brain Structure & Function finds that rapid eye...

Medical News Today: Depression: Discovery of new brain pathway could yield new treatments

Researchers have identified a new brain signaling pathway that alleviates depression when blocked; the discovery could open the door to new treatments.

Evidence of nose-to-brain delivery of nanoemulsions: cargoes but not vehicles.

The nose-to-brain pathway has been proven to be a shortcut for direct drug delivery to the brain. However, whether and to what extent nanoparticles can be delivered through this passage is still await...

From Nose to Brain: Un-Sensed Electrical Currents Applied in the Nose Alter Activity in Deep Brain Structures.

Rules linking patterns of olfactory receptor neuron activation in the nose to activity patterns in the brain and ensuing odor perception remain poorly understood. Artificially stimulating olfactory ne...

Olfaction as a marker for depression.

Olfactory and emotional higher processing pathways share common anatomical substrates. Hence, depression is often accompanied by alterations in olfactory function. These alterations are negative in na...

Localization of α1-2 Fucose Glycan in the Mouse Olfactory Pathway.

Glycoconjugates in the olfactory system play critical roles in neuronal formation, and α1-2 fucose (α1-2Fuc) glycan mediates neurite outgrowth and synaptic plasticity. Histochemical findings of α1-...

Prenatal Alcohol Exposure Affects Progenitor Cell Numbers in Olfactory Bulbs and Dentate Gyrus of Vervet Monkeys.

Fetal alcohol exposure (FAE) alters hippocampal cell numbers in rodents and primates, and this may be due, in part, to a reduction in the number or migration of neuronal progenitor cells. The olfactor...
