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 ...
Richard Caton discovered electrical activity in the cerebral hemispheres of rabbits and monkeys and presented his findings in 1875. [4] Adolf Beck published in 1890 his observations of spontaneous electrical activity of the brain of rabbits and dogs that included rhythmic oscillations altered by light, detected with electrodes directly placed on the surface of the brain.

The length of light exposure influences entrainment. Longer exposures have a greater effect than shorter exposures. [12] Consistent light exposure has a greater effect than intermittent exposure. [14] In rats, constant light eventually disrupts the cycle to the point that memory and stress coping may be impaired. [15]
Phase response curves for light and for melatonin administration. In humans and animals, there is a regulatory system that governs the phase relationship of an organism's internal circadian clock to a regular periodicity in the external environment (usually governed by the solar day).
For phi phenomenon, motion detector would develop to detect a change in light intensities at one point on the retina, then our visual system would compute a correlation of that change with a change in light intensities of a neighboring point on the retina, with a short delay.

Periodic motion is motion in which the position(s) of the system are expressible as periodic functions, all with the same period. For a function on the real numbers or on the integers , that means that the entire graph can be formed from copies of one particular portion, repeated at regular intervals.
