Insomnia Overview

Insomnia, also known as trouble sleeping, is a sleep disorder in which there is trouble to fall asleep or to stay asleep as long as desired.

While the term is sometimes used to describe a disorder as diagnosed by polysomnographic or actigraphic evidence, this is often practically defined as a positive response to either of two questions: "do you experience difficulty sleeping?" or "do you have difficulty falling or staying asleep?"

Sleep Overview

The neuroscience of sleep is the study of the neuroscientific and physiological basis of the nature of sleep and its functions.

The fact that organisms spend about a third of their time in sleep, and that sleep deprivation can have disastrous effects ultimately leading to death demonstrate the importance of sleep. The development of improved imaging techniques like EEG, PET and fMRI, along with high computational power have led to an increasingly greater understanding of the mechanisms underlying sleep.

Scientists Pinpoint Biological Clock’s Synchronicity

Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks.

Their findings, which appear in the journal PLOS Biology, enhance our understanding of how sleep-wake cycles are regulated and offer promise for addressing related afflictions.

Poor sleep: It’s neuroscience, not just a nuisance

In this short video, Oxford University Professor Foster explains that his new findings in neuroscience show that lack of adequate sleep is not just an inconvenience.

He also discusses how these findings have significant implications for future therapies – related to eye disease as well as mental illnesses. Click on the title to see the video.
