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...

Finding the target: How timing is critical in establishing an olfactory wiring map

The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays on...

Parental olfactory experience influences behavior and neural structure in subsequent generations

This study demonstrates an epigenetic inheritance of a learned behavior that is transmitted across generations via the gametes whereby learning about a specific olfactory stimulus changes brain struct...

Sensory systems: Staying silent

Olfactory receptors signal through G protein βγ subunits to silence the expression of other olfactory receptors within a single olfactory sensory neuron.

Olfactory Function in Schizophrenia and Family Members

Could olfactory deficits be a useful marker of schizophrenia risk? This study analyzed current evidence for olfactory dysfunction in schizophrenics, close relatives, and youth at-risk for psychosis....

Study reveals how brain and olfactory system operate to process scent and odor signals

Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action.

Study reveals how brain and olfactory system operate to process scent, odor signals

Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action.

Study suggests nestin+ cholinergic neurons may have closer connection to olfactory bulb neurons

Dr. Yuhong Zhao and co-workers from Sun Yat-sen University in China explored the projection of nestin+ neurons to the olfactory bulb and the time course of nestin+ neurons in the medial septum-diagona...

Brain Connections Explain Why Girls Mature Faster

Newcastle University scientists have discovered that as the brain reorganizes connections throughout our life, the process begins earlier in girls which mayRead more

Electrophoretic particle guidance significantly enhances olfactory drug delivery: a feasibility study.

Intranasal olfactory drug delivery provides a non-invasive method that bypasses the Blood-Brain-Barrier and directly delivers medication to the brain and spinal cord. However, a device designed specif...

Olfactory-related cortical atrophy is associated with olfactory dysfunction in Parkinson's disease.

Olfactory dysfunction is often associated with Parkinson's disease (PD) and can precede characteristic motor symptoms by several years. Olfactory-related cortical atrophy has been reported in PD, alth...

Olfactory Receptor and Neural Pathway Responsible for Highly Selective Sensing of Musk Odors.

Musk odorants are used widely in cosmetic industries because of their fascinating animalic scent. However, how this aroma is perceived in the mammalian olfactory system remains a great mystery. Here,...

Long distance interferon signaling within the brain blocks virus spread.

Serious permanent neurological or psychiatric dysfunction may result from virus infections in the central nervous system (CNS). Olfactory sensory neurons are in direct contact with the external enviro...

Pregnancy and olfaction: a review.

Many women report a heightened sense of smell during pregnancy. Accounts of these anecdotes have existed for over 100 years, but scientific evidence has been sparse and inconclusive. In this review, I...
