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.
That is a bizarre article, but so is the history of tuning! I find the argument of 432 being correct when studying how sound affects water to be much more compelling. A new study would be nice, like the old simple study that played the different tunings (432 + 440) and their octaves for a large sampling of people.
Research has also shown that one can reduce performance in the frequency format by disguising the set-subset relationships in the problem (just as in the standard probability format), thus demonstrating that it is not, in fact, the frequency format, but instead, the highlighting of the set-subset structure that improves judgments.

Studies cited as contrary evidence did not address the physiological brain response to high-frequency audio, only the subject's conscious response to it. Further investigation of the observed physiological response appears to show that the ear alone does not produce the extra brain waves, [ 12 ] but when the body is exposed to high-frequency ...
In human EEG studies, the term theta refers to frequency components in the 4–7 Hz range, regardless of their source. Cortical theta is observed frequently in young children. [ 14 ] In older children and adults, it tends to appear during meditative, drowsy, hypnotic or sleeping states, but not during the deepest stages of sleep .
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 ...
Traditional classification of the frequency bands, that are associated to different functions/states of the brain and consist of delta, theta, alpha, beta and gamma bands. . Due to the limited capabilities of the early experimental/medical setup to record fast frequencies, for historical reason, all oscillations above 30 Hz were considered as high frequency and were difficult to investigate.
A major area of research in neuroscience involves determining how oscillations are generated and what their roles are. Oscillatory activity in the brain is widely observed at different levels of organization and is thought to play a key role in processing neural information. Numerous experimental studies support a functional role of neural ...
