“Aging is associated with many brain changes, apparently including (at least in mice) hyperactivity in hypocretin neurons, leading to more wakefulness and fragmented sleep. This is a good example of how ?changes ➡️ sleep disruption, and not just the other way around.” Dr Jade Wu Duke U sleep scientist
“Age-associated changes in the activity of neurons are responsible for disrupted sleep in older mice, according to a study supported by @NIHAging. As mice age, neurons that control wakefulness become hyperactive, leading to fragmented, poor-quality sleep.”
