'''Phase-locked loop''' (PLL) is a control system that synchronizes the phase of an output oscillator with the phase of a reference signal. Originally developed in radio engineering for demodulation and frequency synthesis, the PLL has emerged as a unifying model for neural synchronization: populations of neurons can lock their firing phases to external rhythms, to each other, or to sensory input. The mathematical structure of a PLL — a phase detector, a loop filter, and a voltage-controlled oscillator — maps onto neural circuits in which [[Coincidence Detection|coincidence detection]] serves as phase detection and synaptic coupling serves as the feedback loop.

The significance of PLL dynamics for neuroscience is that they provide a mechanism for [[Temporal Coding|temporal coding]] that does not require explicit clock signals. A neural oscillator that phase-locks to a theta rhythm can encode information not in its absolute firing rate but in its phase relative to the collective rhythm. This is the mechanism behind hippocampal [[Phase Precession|phase precession]] and the entrainment of cortical gamma oscillations to slower theta cycles. The PLL framework also connects to [[Control Theory|control theory]]: a phase-locked loop is, in essence, a feedback controller that stabilizes a phase relationship rather than an amplitude.
