Their findings point to never-before-seen fast-updating signals in a feedback loop between the brain's olfactory cortex and olfactory bulb. These signals may help put odors and sounds into new ...

Proper brain function relies on exquisite balance between excitation and inhibition, where inhibitory circuits play fundamental roles toward sculpting principle neuron output and information ...

One example is Kallmann syndrome, in which olfactory bulb development is disordered. Individuals with this condition have olfactory loss as well as deterioration in various brain areas, but it is ...

As early as one month of age, odors triggered activity in brain regions strongly associated with the sense of smell, as well as the thalamus, which is important for processing sensory information ...

In September 2024, these miniature pollutants were also discovered in the human olfactory bulb, a type of brain tissue that sits above the nose in the forebrain. At the time, researchers weren’t ...

These cells extend upwards from the roof of your nose towards the smell-processing centre of your brain, called the olfactory bulb. You can lose your ability to smell due to injury or infection – for ...

The olfactory system is the sensory system that is responsible for the sense of smell (olfaction). It receives, processes and interprets odour information. Interactions among insects, plants ...

These findings challenge a long-standing dogma in the field and suggest that different types of receptors, that is, olfactory and ionotropic receptors, can be co-expressed in the same chemosensory ...
