Neuroscience and music

Arguably the greatest concert film of all time. Of course, some would argue The Last Waltz or Woodstock or...

It appears to me that you have a very positive view of Trump. 😏

"These findings indicate that a specific brain state of musical creation is formed ... in which [neurons in] the primary visual and motor areas...are recruited to enhance the functional connectivity between the ACC and the default mode network to plan the integration of musical notes with emotion."

Row A shows areas of decreased connectivity, Row E areas of increased connectivity.

Compared composing vs resting state fMRI of 17 composers. Stronger functional connectivity appeared between anterior cingulate cortex (ACC), right angular gyrus and bilateral superior frontal gyrus during composition.

"This collection explores the science of learning to move and its impact on cognition, how the neuropsychological aspects of the creative movement process is manifested in the brain, and how creative movement or dance can be harnessed to enhance health, cognitive function, and quality of life."

The latest issue of the Journal of Alzheimer's Disease has a special section entitled "Neuropsychological impact and mechanisms of creative movement: Implications for rehabilitation for aging, neurodegenerative disease, and neurotrauma." See link and abstract below. #neuroskyence

Trends in Cognitive Sciences Review Core systems of music perception Samuel A. Mehr 1 ,2 , * 1 School of Psychology, University of Auckland, Auckland, New Zealand Human musicality is supported by two distinct systems of representation: one for tonal perception, which contextualizes pitch input in reference to a hierarchy of tones; and one for metrical perception, which contextualizes temporal input in reference to a hierarchy of rhythmic groupings. Growing evidence suggests that the two systems are universal, automatic, encapsulated, and relatively early-developing. But like speech perception, and unlike several other perceptual systems, they appear to be uniquely human. The systems of tonal and metrical perception form a foundational structure for musicality that, when combined with the processing of other acoustical information (e.g., timbre or auditory scenes), and applied in conjunction with other cognitive domains, yields a human psychology of music.

my latest, in Trends in Cognitive Sciences

this review lays out what I think the fundamental specializations are for music perception in humans, namely, the hierarchical processing of pitch and rhythm

or, how our minds turn vibrating air into music

For drummers: "The experience of groove is a trade-off between stimulus complexity (amount of syncopation) and the ability to maintain a sufficiently stable metre for moving in time with music."

Probably trying to maximize group differences

This hypothesis is supported by the strong association we found between structural differences, musician status, and practice intensity.

Although some of these multiregional differences could be attributable to innate predisposition, [authors] believe they may represent ... adaptations in response to long-term skill acquisition and the repetitive rehearsal of those skills.

More efficient for those who were trained vs untrained later in life. A good argument for music education in schools.

This network constitutes an essential brain substrate for recognition of musical emotion that overlaps with brain regions previously implicated in coding emotional value, behavioural context, conceptual knowledge and theory of mind.
