Neuronal oscillations are an essential part of the functioning of the human brain. They regulate the communication between neural networks and the processing of information carried out by the brain by pacing neuronal groups and synchronising brain regions. This important finding reveals that strictly-timed communication between brain regions can be achieved by high-frequency oscillations. Carrying out a visual task resulted in the synchronisation of high-frequency oscillations in the specific brain regions responsible for the task execution. These observations suggest that high-frequency oscillations convey within the brain ‘information packages’ from one small neuronal group to another.
