Musical instrumental reading affects middle cerebral blood flow and cognitive function

Area of Science:

• Neuroscience
• Cognitive Psychology
• Musicology

Background:

• Musical performance involves complex cognitive processes including reading music, playing an instrument, and auditory processing.
• The specific factors contributing to increased cerebral blood flow (CBF) during music performance remain unclear.
• Understanding the neural correlates of music engagement can provide insights into cognitive function and brain plasticity.

Purpose of the Study:

• To investigate the factors contributing to increased middle cerebral artery velocity (MCAv) during musical performance.
• To examine the effects of playing and reading music on cognitive function.
• To differentiate the impact of music reading versus playing from memory on cerebral hemodynamics.

Main Methods:

• Seventeen musicians participated in a randomized controlled study.
• Participants engaged in three conditions: playing with music, playing from memory, and reading music scores, each for 10 minutes.
• Middle cerebral artery velocity (MCAv) was continuously monitored before, during, and after each musical task.
• Cognitive function was assessed using the Stroop test before and after the musical tasks.

Main Results:

• MCAv showed significant increases during all three conditions: reading music, playing from memory, and reading music scores.
• Stroop test performance significantly improved after the music reading condition.
• These results indicate that both the act of reading music and playing an instrument contribute to elevated MCAv.

Conclusions:

• Both music reading and instrumental playing are implicated in the observed increase in MCAv during music performance.
• Music reading appears to provide a transient enhancement of cognitive functions, as evidenced by improved Stroop test scores.
• The study highlights the multifaceted cognitive demands of musical engagement and their impact on cerebral blood flow and cognitive performance.
