Sleep is indispensable for health and wellbeing, but its basic function remains elusive. The locus coeruleus (LC) powerfully promotes arousal by releasing noradrenaline. We found that noradrenaline transmission is reduced by prolonged wakefulness and restored during sleep.

- The study examines how patterns of neuron activation in the mouse visual cortex change over time during sensory experiences and reactivations.
- Researchers found that reactivations that occur shortly after a visual stimulus can predict how these sensory representations will shift both within a day and over multiple days.
- These findings suggest that reactivations of neuronal activity may play a significant role in modifying and refining sensory responses, improving the brain's ability to distinguish between different stimuli.
