Using EEG to measure REM sleep allowed scientists to distinguish dreaming from wakefulness.
Using optogenetics, researchers manipulated pulses of neural activity during non REM sleep that made mice either remember of forget things they had learned. This novel study demonstrated that altering sleep spindle oscillations during sleep has an impact on memory formation and retention.
A new study links poor sleep quality in older adults with elevated levels of tau, a protein associated with Alzheimer's disease. Researchers report poor sleep quality later in life may be associated with declining brain health and may be an early indicator of Alzheimer's disease.
Natural, restorative sleep can help stave off mental and physical decline as we age.
A new study reveals how tactile experiences are encoded in the brain as we sleep.
Researchers report the size of the pupil fluctuates during sleep. The findings may indicate that pupil size can indicate specific sleep states.
A new study sheds additional light on how the brain consolidates memory during sleep. Researchers report rapid fluctuations in gamma band activity in the hippocampus during nREM sleep helps facilitate memory reactivation.
A new study MEG study reveals our ability to learn during slow wave sleep is limited.
Researchers at Johns Hopkins have identified specific neurons in the zona incerta that appear to help promote sleep. The discovery could help develop new treatments for insomnia and other sleep disorders.
