Widespread ripples synchronize human cortical activity during sleep, waking, and memory recall

In short

The authors recorded brain activity from inside human heads to see if fast brain waves called ripples happen at the same time across different parts of the cortex during sleep, waking, and memory tasks. They found that these ripples frequently occur together over long distances and lock into specific timing patterns, especially right before people successfully recall memories. This suggests that synchronized high-speed signals between widely separated brain regions are a key mechanism for linking separate pieces of information into unified thoughts.
