Study shows how memories ripple through the brain

NIH-funded study suggests increased communication between key brain areas during sleep. Using an innovative “NeuroGrid” technology, scientists showed that sleep boosts communication between two brain regions whose connection is critical for the formation of memories. The work, published in Science, was partially funded by the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a project of the National Institutes of Health devoted to accelerating the development of new approaches to probing the workings of the brain.

Rhythm of memory

Inhibited neurons set the tempo for memory processes. The more we know about the billions of nerve cells in the brain, the less their interaction appears spontaneous and random. The harmony underlying the processing of memory contents has been revealed by Prof. Dr. Marlene Bartos’ workgroup at the Institute of Physiology I.
