You're fast asleep. But your brain isn't taking the night off, according to new research funded by the U.S. National Science Foundation. Researchers studied activity in the human cerebral cortex in response to music and other sounds. They observed vigorous auditory responses in the sleeping brain, similar in many ways to responses in the wakeful state but differing in a key component. While the waking state is characterized by ongoing feedback signals in the brain as it attends to and interprets incoming sounds, researchers found that those signals are greatly reduced during sleep.

Making connections requires brain circuits to be active and interact during sleep

Relational memory is the ability to remember arbitrary or indirect associations between objects, places, people or events -- such as names and faces.

Previous research has established that animal and human memory benefits from quality sleep. In a new U.S. National Science Foundation-supported study published in The Journal of Neuroscience, Maxim Bazhenov and Timothy Tadros of the University of California San Diego

School of Medicine developed a modeling approach that may explain the underlying mechanisms that strengthen or create new relational memories during sleep.

"This new computational research provides insights into the importance of sleep for the consolidation of memory," said NSF program director Jonathan Fritz.
