WebApr 11, 2024 · We used to make clocks with large pendulums. Sellers normally had several of them in their shop. They noticed how they eventually swung in unison, led by the clock with the strongest rhythm. If an even bigger and stronger pendulum clock was introduced, all other clocks soon shift to its rhythm. Nature tends to follow the dominant leader. WebEntrainment is an important characteristic of interactions between brain rhythms and refers to the coupling of two independent oscillatory systems in such a way that their periods of oscillation become related by virtue of phase alignment (Cummins, 2009).

"WebWhen photoperiod (i.e. daytime) gets longer than 12hr, a Phase Jump (also called ψ Jump, where ψ is the phase angle of entrainment) occurs, where the original nocturnal activity jumps to the now longer daytime, and ψ changes abruptly since the clock now treats the second light pulse as light onset and the start of the day.

This “phase of entrainment” varies in individuals. These so-called “chronotypes” from a distribution ranging from extremely early “larks” to extremely late “owls”, ...

WebEntrainment is the synchronization of the internal clock with the external world. Clocks exist in many organs in an animal, so entrainment ensures that the clocks work well together. A zeitgeber, or time-giver, is the external cue that entrains the clock. To understand how zeitgebers work a little background on clocks helps.

WebOct 14, 2024 · Circadian clocks provide a temporal structure to most biological processes. These internal circa 24-h clocks entrain to predictable signals in the environment (termed “zeitgebers”) that cue time of day or season ( Box 1 ). The regulation of phase of entrainment contributes the adaptive advantage of the circadian clock [ 1, 2 ].
