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...

Spatially segregated feedforward and feedback neurons support differential odor processing in the lateral entorhinal cortex

The lateral entorhinal cortex computes and transfers olfactory information from the olfactory bulb to the hippocampus and supports associative multimodal memories. Leitner et al. characterize the acti...

Topographical representation of odor hedonics in the olfactory bulb

Hedonic value is a dominant aspect of olfactory perception. The authors combine immediate early gene mapping and optogenetics to show that the degree of behavioral attraction to odors is represented a...

Dense EM-based reconstruction of the interglomerular projectome in the zebrafish olfactory bulb

The authors used new 3D electron microscopy techniques and analyses to reconstruct virtually all neurons in the olfactory bulb of a zebrafish larva. The results reveal specific patterns of projections...

Gastrointestinal disorders involve both brain-to-gut and gut-to-brain pathways

New research indicates that in patients with irritable bowel syndrome (IBS) or indigestion, there is a distinct brain-to-gut pathway, where psychological symptoms begin first, and separately a distinc...

A 'time switch' in the brain improves sense of smell

When the brain processes olfactory stimuli, it differentiates between similar smells using subtly modulated signals. Brain examinations and behavioral studies in mice have now shown that neurons with ...

Odor alternative: 'Olfactory necklace' detects scents in a way contrary to neurobiology dogma

Mammals have an exquisitely tuned sensory system that tells them whether they are smelling an orange or a rose. Like keys on a piano keyboard, each component of an odor blend strikes only one chord of...

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...

Lewy body pathology involves the olfactory cells in Parkinson's disease and related disorders.

The "dual-hit" and propagation hypotheses of α-synuclein suggests that the olfactory cells of the olfactory epithelium are among the earliest sites of involvement in Parkinson's disease (PD). We inve...

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-...

Expression of polysialyltransferases (STX and PST) in adult rat olfactory bulb after an olfactory associative discrimination task.

Neuronal plasticity and neurogenesis occur in the adult hippocampus and in other brain structures such as the olfactory bulb and often involve the neural cell adhesion molecule NCAM. During an olfacto...
