Question

When jazz players improvise, MRI scans show ______. a. no differences in brain activity b. that musicians tended to switch on the self-censoring part of their brain c. that musicians tended to switch off the self-censoring part of their brain giving them the ability to express themselves without restriction d. decreased brain activity

Answer 1

MRI scans show that during improvisation, musicians typically deactivate the self-censoring parts of their brain, enabling free musical expression. This is measured using fMRI, which detects increased blood flow and oxygen use in active brain regions. Option b

Step-by-step explanation:

When jazz players improvise, MRI scans show that musicians tend to switch off the self-censoring part of their brain giving them the ability to express themselves without restriction. This is because the improvisational aspect of jazz requires musicians to be highly creative and spontaneous, making decisions in the moment without the time for self-criticism or extensive planning.

Functional MRI (fMRI) technology measures changes in blood flow to active areas of the brain, indicating where neural activity is heightened.

An example of this can be deduced from general fMRI scans which demonstrate that during any complex task, such as improvising, there is substantial brain activity, often involving visual sensory areas, integrating areas, motor areas for moving and controlling limbs, and potentially even more, depending on the specifics of the task. Option b
