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...

What the Nose Knows

The nose, of course, knows nothing. The information we gather from the basic odor-detection task performed by molecular receptors in the nose needs to be processed in the brain’s olfactory bulb and ...

New Neurons Needed to Maintain Smell Circuits

Scientists have previously described the continuous generation of newborn neurons in restricted regions of the adult mammalian brain, a process referred to as adult neurogenesis. Investigators at the ...

Olfactory bulb coding of odors, mixtures and sniffs is a linear sum of odor time profiles

Due to their volatility, olfactory inputs are spatially and temporally dynamic. Here the authors find that, in contrast to previous studies, mitral/tufted cells of the olfactory bulb can sum inputs li...

Notch cell signaling pathway goes awry in common pediatric brain tumor

A new study links a well-known cell communication pathway called Notch to one of the most common -- but overall still rare -- brain tumors found in children.read more

Cell signalling pathway goes awry in common paediatric brain tumour

A new study by Johns Hopkins researchers links a well-known cell communication pathway called Notch to one of the most common – but overall still rare – brain tumours found in children. Their s...

New brain pathway offers hope for treating hypogylcemia

(University of Michigan Health System) A novel pathway buried deep within a region of the brain produces a brain hormone that acts as a crucial sensor of blood glucose levels. Learning how the hormon...

How brain can distinguish good from bad smells

In fruit flies, the quality and intensity of odors can be mapped in the so-called lateral horn, scientists have found. They have created a spatial map of this part of the olfactory processing system i...

Hopkins researchers find that cell signaling pathway goes awry in common pediatric brain tumor

A new study by Johns Hopkins researchers links a well-known cell communication pathway called Notch to one of the most common -- but overall still rare -- brain tumors found in children.

Olfactory and executive dysfunctions following orbito-basal lesions in traumatic brain injury.

To study the acute relationship between olfactory function and traumatic brain injury (TBI), cognitive functions and outcome.

The muted sense: neurocognitive limitations of olfactory language.

Most people find it profoundly difficult to name familiar smells. This difficulty persists even when perceptual odor processing and visual object naming are unimpaired, implying deficient sensory-spec...

Lesion of the Olfactory Epithelium Accelerates Prion Neuroinvasion and Disease Onset when Prion Replication Is Restricted to Neurons.

Natural prion diseases of ruminants are moderately contagious and while the gastrointestinal tract is the primary site of prion agent entry, other mucosae may be entry sites in a subset of infections....

The olfactory groove schwannoma attached to the cribriform plate: a case report.

The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She h...

Direct nose-to-brain delivery of lamotrigine following intranasal administration to mice.

Pharmacoresistance is considered one of the major causes underlying the failure of the anticonvulsant therapy, demanding the development of alternative and more effective therapeutic approaches. Due t...
