Neurons are sensitive to signal arrival within fractions of a millisecond, and oscillations unify signals from different brain regions.

“Well, my neurons are very sensitive to changes in signals arriving by fractions of a millisecond. So, I know we're sure that those signals coming in represent the same signal. Well, if I have throughout my brain and isolation and the signals ride on that oscillation, let's say the peak of the oscillation, I can then have a much better handle on the road of timing and say, "Those two signals came in at the same time. They may relate to the same object and ah ha, I see you as one unified thing spouting talking."”
