Sleep deprivation may additionally affect memory by reducing the proliferation of cells in the hippocampus. [51] Sleep deprivation has also been associated with decreased overall membrane excitability of neurons in the brain. Activation of these membranes is critical for the formation of memories. [52]
The negative effects of sleep deprivation on alertness and cognitive performance suggest decreases in brain activity and function. These changes primarily occur in two regions: the thalamus , a structure involved in alertness and attention, and the prefrontal cortex , a region subserving alertness, attention, and higher-order cognitive ...

In other words, these results suggest that shorter sleep duration interacts with high blood pressure to increase the risk of poor cognitive function and greater brain injury. How much sleep a ...
The dysregulation model is supported by neuroanatomical, physiological, and subjective self-report studies. Emotional brain regions (e.g. the amygdala) have shown 60% greater reactivity to emotionally negative photographs following one night of sleep deprivation, as measured by functional magnetic resonance imaging.

A long-term lack of sufficient sleep is linked to dementia and Alzheimer’s, but this new research suggests this is not due to brain clearing during sleep. All mammals sleep, yet we are note ...
While stress and sleep greatly impact each other, their effect permeates into many more aspects of daily life. One specific concern is the harmful effects on cognitive performance and attention span. In addition, sleep deprivation can cause a change in perceptions as well.
Though it’s normal to have trouble falling asleep and/or staying asleep occasionally, prolonged periods of sleepless nights and chronic sleep deprivation can harm not only our bodies, but our minds.
