Neuronal activity at the microscopic level has a stochastic character, with atomic collisions and agitation, that may be termed "noise." [4] While it isn't clear on what theoretical basis neuronal responses involved in perceptual processes can be segregated into a "neuronal noise" versus a "signal" component, and how such a proposed dichotomy could be corroborated empirically, a number of ...
Adverse cardiovascular effects occur from chronic exposure to noise due to the sympathetic nervous system's inability to habituate. The sympathetic nervous system maintains lighter stages of sleep when the body is exposed to noise, which does not allow blood pressure to follow the normal rise and fall cycle of an undisturbed circadian rhythm.

All of the ways your presentation could go wrong swirl in your mind. Yesterday's tense exchange with your boss plays on a loop. Worry about the threat of layoffs, a recent parenting mishap, and an ...
Annoyance implies a negative factor on an individual's well-being and comfort. Its effects may include physiological responses, central nervous system reactions, and biochemical changes. [1] Physiological reactions to sound annoyance include increased heart rate and increased blood pressure which, among others, may lead to hypertension.
The neural encoding of sound is the representation of auditory sensation and perception in the nervous system. [1] The complexities of contemporary neuroscience are continually redefined. Thus what is known of the auditory system has been continually changing.
As a stand-alone condition, "ataxia is a degenerative disease of the nervous system," explains Andrew Rosen, chief executive officer of the National Ataxia Foundation. There are many types ...
These are the first acoustic neurons of the central nervous system. Studies have shown a direct correlation to the amount of decrease of the startle to the number of CRNs that were killed. Second, there is a synapse from the CRN axons to the cells in the nucleus reticularis pontis caudalis (PnC) of the brain.
People with misophonia display hypersensitivity to certain pattern-based noises such as the sound of chewing, slurping, finger tapping, foot shuffling, throat clearing, pen clicking, and keyboard tapping; people with misophonia respond to triggering sounds with emotional distress and increased hormonal activity of the sympathetic system.
