New statistical models based on rigorous physiological data from more than 100 surgeries provide objective, accurate measures of 'nociception,' the body's subconscious perception of pain. The degree ...

Researchers at UC Santa Barbara identified a pain pathway in fruit flies that reduces the sensation of pain from heat. The researchers discovered that just a single neuron on each side of the animal’s ...

Inner hair cells (IHCs) and outer hair cells (OHCs) in the cochlear organ of Corti (OOC) are destroyed by high-amplitude, persistent sound; however, because the OOC is not innervated by somatosensory ...

In nociception, a range of G-Protein-Coupled Receptors (GPCRs) plays extremely important roles. By modulating the function of a wide variety of ion channels, GPCRs also signal molecules in the case of ...

Our ears have built-in secret "bodyguards" that protect them from extremely loud, potentially damaging noise, researchers say. A newly detected connection between the inner ear and the brain can warn ...

People sometimes mistakenly think of general anesthesia as just a really deep sleep but in fact, anesthesia is really four brain states -- unconsciousness, amnesia, immobility and suppression of the ...

The neural mechanisms of many symptoms associated with migraine have yet to be elucidated. New research suggests that a non-image-forming retinal pathway and signals from the dura mater contribute to ...

Osaka, Japan - Candida albicans infection (candidiasis) can cause skin, genital, or oral pain. Many studies have attempted to understand the source of pain in candidiasis; none have provided a clear ...
