Learn to the rhythm: Nerve cells acting as metronomes are necessary for certain memory processes

Usually, we associate rhythms with dance and music. But they also play an important role in the brain. When billions of neurons communicate with each other, certain rhythmic activity patterns arise. The proper metre in this interplay is provided by nerve cells that do not excite other cells, but inhibit their activity instead. One type of these inhibiting cells acts in a particularly fast and efficient way and is therefore thought to be crucial for memory formation and information processing in neuronal networks. Scientists can now specifically switch off this cell type and to observe the consequences for memory formation.
