Additionally, lack of sleep causes increased anxiety-like behaviors and impairs the brain's ability to block out unimportant stimuli when performing tasks requiring attention. Disruptions in important brain circuits and the downregulation of proteins necessary for cognitive stability are the causes of these behavioral abnormalities. [30]
Cognitive impairment ("brain fog") includes an inability to recall words, short-term memory loss, an inability to multi-task, misspelling and mispronunciation of words, difficulty in concentrating. Many MdDS sufferers report they are unable to use a computer for any length of time due to the visual overstimulation, and some are even unable to ...
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 ...
The earliest warning signs of Alzheimer's disease include memory loss that impacts your daily functioning, vision and language issues, social withdrawal, and more.
You may have heard of white noise used to mask background sounds. The science is new with only a few small studies behind it, but that hasn’t stopped thousands of people from listening to hours ...
Noise-induced hearing loss is a permanent shift in pure-tone thresholds, resulting in sensorineural hearing loss. The severity of a threshold shift is dependent on duration and severity of noise exposure. Noise-induced threshold shifts are seen as a notch on an audiogram from 3000 to 6000 Hz, but most often at 4000 Hz. [16]
Brown noise is a low-frequency sound. Can it really help with focus, sleep, and controlling anxiety?
[1] [6] [7] Glucocorticoids facilitate and impair the actions of stress in the brain memory process. [8] Cortisol is a known biomarker for stress. [9] Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones.
