Webcally spike in coordination with the local theta-frequency oscillation (5–10 Hz). This process is called“precession” because these place cells spike slightly faster than the theta oscillation as the rodent runs through specificlo-cations, and it results in sequences of locations being encoded at different phases oftheta oscillations.
