Sleep helps to stabilize long-term memories, possibly through the temporal synchronization of neuronal activity in different brain regions. Intracranial stimulation during sleep using prefrontal electric pulses, precisely timed with slow-wave activities in the medial temporal lobe, enhanced the coupling of neuronal oscillations across regions of the human brain and improved memory performance.
