The link between diseases such as Alzheimer’s and sleep loss has been frequently cited by researchers, and a new study led by scientists from the University of Pennsylvania has discovered a signaling ...

The model of sleep homeostasis regulation proposed in this study. Prolonged wakefulness activates CaMKII in PV-expressing neurons. The activated CaMKII then activates PV-expressing neurons, leading to ...

Sleep is known to be central to various physiological and mental processes, including the consolidation of memories, supporting various cognitive functions, helping to clear the brain of neurotoxins, ...

A poster that was presented in the Tenth University Research Day at the Catholic University of America in 2025. The complex neurobehavioral process of sleep is essential in the maintenance of good ...

While it’s well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new ...

Melatonin is a naturally produced molecule that has long been suspected to play a role in healthy sleep, but it has been ...

The mechanisms in the brain that should reduce pain don’t work as well in people with migraine when they haven’t gotten enough sleep. For the first time, researchers have studied what happens in the ...

Scientists reveal how sleep, especially naps, boosts motor learning after TBI, offering new insights into brain activity and rehabilitation strategies to enhance recovery outcomes. New research ...

Research into sleep function and mechanisms has revealed a remarkable degree of conservation across species, from invertebrates such as Drosophila to complex vertebrates. In Drosophila, sleep is not ...
