In response to light exposure, alertness levels can increase as a result of suppression of melatonin secretion. [3] [6] A linear relationship has been found between alerting effects of light and activation in the posterior hypothalamus. [3] [24] Disruption of circadian rhythm as a result of light also produces changes in metabolism. [4]
Summary of pervasive effects of light. The SCN of the hypothalamus contains an endogenous pacemaker that regulates circadian rhythms. [4] The zeitgeber found to have the most profound effect on the SCN is light, which is the form of stimulation of which conversion is needed for it to be processed by the brain. Neurotransmitters that travel the ...
Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, [1] speech, [2] music, [3] or tactile stimuli.
An example is the phenomenon of tapping to the beat, where the listener anticipates the rhythmic accents in a piece of music. Another example is the effect of music on movement disorders: rhythmic auditory stimuli have been shown to improve walking ability in Parkinson's disease and stroke patients. [41] [42]
The ability to perceive and generate music is frequently studied as a way to further understand human rhythmic processing. Research projects, such as Brain Beats, [9] are currently studying this by developing beat tracking algorithms and designing experimental protocols to analyze human rhythmic processing. This is rhythm in its most obvious form.
The psychology of music, or music psychology, may be regarded as a branch of psychology, cognitive science, neuroscience, and/or musicology.It aims to explain and understand musical behaviour and experience, including the processes through which music is perceived, created, responded to, and incorporated into everyday life.

These rhythms include the sleep–wake cycle, hormone production, and core body temperature cycles. The timing of these patterns is set by the 24-hour light–dark cycle. In particular, short-wavelength "blue" light in the daylight spectrum has maximal effect on human circadian rhythms. Research has shown that when these patterns are disrupted ...
