Study sheds light on how the brain processes emotions during dream sleep by consolidating positive emotions while dampening the consolidation of negative emotions. The findings could pave the way for new treatments for PTSD and other disorders associated with negative emotional processing.
People who suffer from REM behavioral disorder, a sleep disorder linked to an increased risk of developing Parkinson's disease, exhibit limited movement of their trunk during dream re-enactment.
Students who consistently sleep the optimal eight hours per night perform better on tests and report higher personal satisfaction than their peers who have more disrupted sleep patterns.

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.
