The female nose always knows: Do women have more olfactory neurons?

(Publicase Comunicação Científica) Using a new method called isotropic fractionator, a group of researchers has found biological evidence that may explain the superior olfactory abilities that wome...

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 ...

An olfactory cocktail party: figure-ground segregation of odorants in rodents

Being able to perceive an individual odor in a continually changing and rich olfactory environment is a challenging task. Here, Rokni and colleagues find that this olfactory cocktail party problem can...

Variations in Neuronal Networks Could Explain Traumatic Brain Injury Outcomes

A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behavior...

Medical News Today: Impaired brain signaling pathway 'may be a cause of Alzheimer's'

Mayo Clinic researchers say a brain signaling defect in the Wnt pathway may be a cause of Alzheimer's, and boosting Wnt signaling could prevent the disease.

Ultrasound tracks odor representation in brain

A new ultrasound imaging technique has provided the first ever in vivo visualization of activity in the piriform cortex of rats during odor perception. This deep-seated brain structure plays an import...

Inside the teenage brain: New studies explain risky behavior

It's common knowledge that teenage boys seem predisposed to risky behaviors. Now, a series of new studies is shedding light on specific brain mechanisms that help to explain what might be going on ins...

Gene critical for proper brain development discovered

A genetic pathway has been found that accounts for the extraordinary size of the human brain. The research team has identified a gene, KATNB1, as an essential component in a genetic pathway responsibl...

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...

Roles of olfactory system dysfunction in depression.

The olfactory system is involved in sensory functions, emotional regulation and memory formation. Olfactory bulbectomy in rat has been employed as an animal model of depression for antidepressant disc...

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...

Allosteric Modulation of GABAA Receptors by an Anilino Enaminone in an Olfactory Center of the Mouse Brain.

In an ongoing effort to identify novel drugs that can be used as neurotherapeutic compounds, we have focused on anilino enaminones as potential anticonvulsant agents. Enaminones are organic compounds ...
