Monitoring how a sheep’s sleep changes during the progression of a brain disease may one day translate to sleep-based diagnosis in humans. A specific brain wave type shared by sheep and humans could help researchers study human brain disorders. People may count sheep when they cannot sleep, b...
Brain radiates a number of waves that are classified based on frequency and are named as gamma, alpha, beta, theta & delta. We spend nearly one-third of our lives asleep. Sleep is crucial for concentration, memory, coordination and even emotional health. Without enough sleep, people have ...
Whatever might be causing that bad night’s sleep, it’s going to affect your health. Sleep plays a vital role in maintaining your overall physical and mental well-being. There is simply no remedy for poor sleep. To get a better understanding of what happens when you sleep, and what you...

waves. They are associated with a high state of vigilance, or cognitive activity. Slow waves correspond to theta (4 to 8Hz) and delta waves (1 to 4Hz), and are associated with a state of drowsiness and sleep, respectively. These waves correspond to a slow depolarization of the neurons,...
Delta waves, like other brain waves, are recorded with an electroencephalogram (EEG) and are usually associated with the deepest stages of sleep (3 and 4 NREM), also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep. ...
Sleep loss can affect memory in seniors Researchers studied the brain waves of a small group of adults as they listened to the recorded sounds of a bell ringing. Memory maximizers: here's the latest research to help you keep your brain sharp The size and direction of the brain waves can ...

Gentle sound stimulation—such as the rush of a waterfall—synchronized to the rhythm of brain waves significantly enhanced deep sleep in older adults and improved their ability to recall words, reports a new Northwestern Medicine study.
But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night. UC Berkeley researchers have found compelling evidence that bursts of brain waves known...
