A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light, is an example of the stroboscopic effect being applied to a cyclic motion that is not rotational. When viewed under normal light, this is a normal water fountain.
A light and sound machine with headphones and strobe light goggles. A mind machine (aka brain machine or light and sound machine) uses pulsing rhythmic sound, flashing light, or a combination of these. Mind machines can induce deep states of relaxation [1] or concentration. [2]
A strobe light flashing at the proper period can appear to freeze or reverse cyclical motion. A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary.
The term "agnosia" refers to a loss of knowledge. Acquired music agnosia is the "inability to recognize music in the absence of sensory, intellectual, verbal, and mnesic impairments". [11] Music agnosia is most commonly acquired; in most cases it is a result of bilateral infarction of the right temporal lobes.
Interestingly, music-induced emotions and memories were also found to be preserved even in patients suffering from severe dementia. Studies demonstrate beneficial effects of music on agitation, anxiety and social behaviors and interactions. [14] Cognitive tasks are affected by music as well, such as episodic memory and verbal fluency. [14]
A subset of musical gestures is what could be called music-related body movement, which can be seen from either the performer's or the perceiver's point of view: Performer - movements that are part of a music performance or a performance with music: Sound-producing: musician or actor creating musical sound.
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]
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
