Infants produce sleep spindles every 10 second, whether in REM or non-REM sleep. Sleep spindles and twitching are synchronized, allowing for twitch reactions to occur during non-REM sleep in infants.
Changes in sleep patterns in older men have been linked to an increased risk of cognitive decline, researchers report.
Study reveals the immune system constantly communicates with the brain during the early developmental phase of Parkinson's disease. Changes in the immune system influence the condition of neurons.
When a child reaches the age of two-and-a-half, the primary purpose of sleep changes from brain-building to brain maintenance and repair, a role it maintains for the rest of our lives.
Using EEG to measure REM sleep allowed scientists to distinguish dreaming from wakefulness.
Suppressing the activity of hypothalamic neurons in mice during REM sleep resulted in a decrease in the amount of food later consumed. The study suggests REM sleep is essential to stabilize food intake.
During non-REM sleep, visual areas of the brain exhibit an excitation/inhibition balance indicative of increased plasticity. REM sleep appears to be essential for people to reap the benefits of the increased plasticity that occurs during NREM sleep.
Adult born neurons are essential for synaptic structural remodeling and memory consolidation during REM sleep, a new mouse study found.
