Onset Sound, the Mozart Effect as Alpha Brain Waves and why silence is golden: The Harmonics of Flicker-Fusion-Frequency as non-commutative phase

These scientists have made an excellent argument building on Hameroff and Penrose -

But they don't seem to have realized the secret of non-commutative phase! Something that Hameroff and Penrose now emphasize (but their "followers" apparently have not emphasized).

So then we get a "neuromusical critique"

So he is more of a musician looking to incorporate neuroscience. But again he does not seem to be aware of noncommutative phase as 1/2 spin.

For temporal patterns, no memory transfer was observed after time reversals, showing that both the time intervals and their order were represented in memory.

Memory of sound tied to noncommutative time

  In particular, binaural cues present at sound onset tend to dominate perception (Stecker et al., 2013), a phenomenon that is dramatically illustrated by the Franssen effect (Franssen, 1960; Hartmann and Rakerd, 1989), and depicted in Figure 1A. This illusion occurs when the onset (i.e., the first few milliseconds) and the remainder of a sound are presented from different loudspeakers in a room. The entirety of the sound is perceived to emanate from the onset loudspeaker for several seconds or more, even though the other loudspeaker presents nearly all of the sound energy.

 Franssen stimuli, suggesting a possible subcortical origin of the illusion.

  information flows from core AC regions (e.g., primary AC) to higher-order AC regions located anterior and posterior to the core. Functionally, posterior regions appear more sensitive to the spatial aspects of sounds and tasks, while anterior regions appear more strongly involved with non-spatial aspects such as sound identity (Rauschecker and Scott, 2009).

 And the secret of why silence is golden:

Repeated exposure to a novel noise during Rapid Eye Movements (REM) or light non-REM (NREM) sleep leads to improvements in behavioral performance upon awakening. Strikingly, the same exposure during deep NREM sleep leads to impaired performance upon awakening.

 In light NREM sleep, subcortico-cortical processes, potentially stimulus-driven, would occur (type-I slow waves, corresponding approximately to K complexes), leading to high-amplitude, steep and widespread slow waves. These type-I waves could be associated to activations of the arousal system, restoring some ability to process sensory information and to form new memory traces. In deep NREM sleep, however, slow waves (type-II) would arise from local cortico-cortical synchronization processes, and could subserve the deep NREM suppressive effect observed. Accordingly, the suppression effect was paralleled with the emergence of more numerous but more local, and putatively cortico-cortical, slow waves. Nonetheless, further investigations are needed to prove the relationship between deep NREM sleep slow waves and the suppression of memories, as our interpretation is mostly based on correlational analyses.Understanding why both REM sleep and light NREM sleep favor learning while deep NREM sleep suppresses it could provide a unified view of the impact of sleep on memory formation.

Indeed, the mechanisms underlying the perceptual learning of acoustic noise are still unclear.

Why I was able to memorize the 2nd movement of Bach's Italian Concerto in F much faster than the rest of the concerto

 Increased memory load is often signified by enhanced neural oscillatory power in the alpha range (8–13 Hz), which is taken to reflect inhibition of task-irrelevant brain regions....Correspondingly, temporal expectation also boosted alpha connectivity within attention networks known to play an active role during memory maintenance. The present data show how patterns of alpha power orchestrate short-term memory decay and encourage a more nuanced perspective on alpha power across brain space and time beyond its inhibitory role.

 Music listening - still proven to be right-brain dominant!

Using functional magnetic resonance imaging (fMRI), we found that violations to non-local dependencies in nested sequences of three-tone musical motifs in musicians elicited increased activity in the right IFG. This is in contrast to similar studies in language which typically report the left IFG in processing grammatical syntax. Effects of increasing auditory working demands are moreover reflected by distributed activity in frontal and parietal regions.

Our study therefore demonstrates the role of the right IFG in processing non-local dependencies in music, and suggests that hierarchical processing in different cognitive domains relies on similar mechanisms that are subserved by domain-selective neuronal subpopulations.

Dang - it's a slam dunk! People who can't process music tones have much less right brain activity!

 


Bring it on! Us music freaks perceive the world differently!


Pitch Perception....right brain dominant!
