In the study of chronobiology, entrainment refers to the synchronization of a biological clock to an environmental cycle. An example is the interaction between circadian rhythms and environmental cues, such as light and temperature. Entrainment helps organisms adapt their bodily processes according to the timing of a changing environment. [1]
This ability to align behaviors such as feeding and activity to the external environmental cycle is a process called entrainment. [ 5 ] Biological rhythms , including cycles related to sleep and wakefulness, mood, and cognitive performance, are synchronized with the body's internal circadian clock . [ 6 ]
Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...
Entrainment (chronobiology), the alignment of a circadian system's period and phase to the period and phase of an external rhythm; Entrainment (engineering), the entrapment of one substance by another substance; Entrainment (hydrodynamics), the movement of one fluid by another; Entrainment (meteorology), a phenomenon of the atmosphere
Others, with a "daily" cycle upwards of 25 hours or more, may need to adopt a sleep pattern that is congruent with their free-running circadian clock: by daily shifts in their sleep times, which often results in satisfactory sleep but with negative social and occupational consequences. [citation needed]
All of the mechanisms of light-affected entrainment are not yet fully known, however numerous studies have demonstrated the effectiveness of light entrainment to the day/night cycle. Studies have shown that the timing of exposure to light influences entrainment; as seen on the phase response curve for light for a given species. In diurnal (day ...
The concept of social tipping points has been applied to analyze global decarbonization pathways and the ability to activate contagious and fast-spreading processes of social and technological change that would accelerate carbon emission reductions needed to achieve the goals of the Paris Agreement.
Central pattern generators (CPGs) are self-organizing biological neural circuits [1] [2] that produce rhythmic outputs in the absence of rhythmic input. [3] [4] [5] They are the source of the tightly-coupled patterns of neural activity that drive rhythmic and stereotyped motor behaviors like walking, swimming, breathing, or chewing.
