Nasal injections comprising platelet-rich plasma derived from a patient's blood improve symptoms of smell loss associated with COVID-19 infection.
Researchers have identified an organelle within neurons we use to perceive different odors.
Study reveals an integral feature in how our brains recognize different smells.
The Chlamydia pneumoniae bacteria can travel directly from olfactory nerve in the nose and into the brain, forcing brain cells to deposit amyloid beta and inducing Alzheimer's pathologies. Researchers say protecting the lining of the nose by not picking or plucking nasal hairs can help lower Alzheimer's risks.
In the olfactory system, tufted cells are better at recognizing smells than mitral cells. Tufted cells are one of two parallel neural circuit loops that help the brain process different odor features. The findings shed light on how the brain takes in sensory information that influences behavior and emotion.
The effects of COVID-19 infection on neurological health are becoming more apparent. A new study reveals COVID-19 can predispose people to irreversible neurological conditions, accelerate brain aging, and increase the risk of stroke and brain bleeds.
Smell loss in older individuals not only can predict cognitive decline, but it can also foretell structural changes in brain structures linked to Alzheimer's disease, a new study reports.
Study reveals how olfactory neurons adapt to the surrounding environment.
Anosmia, the loss of the sense of smell which is a common symptom of COVID-19, may be a secondary consequence of immune system inflammation rather than a direct action of the virus.
Centrifugal fibers which carry impulses from parts of the central nervous system to early sensory regions of the brain play a critical role in olfactory processing.
