Quizplus · Accepted Answer

Functional MRI (fMRI) is the best choice for determining brain activation while reading. fMRI produces images of brain activity by measuring changes in blood flow, which indicates neural activity in specific regions of the brain. This is a safe and non-invasive technique that has been used in many studies of language and reading comprehension in older adults. A and B are also imaging techniques that can measure brain activity, but fMRI has higher spatial resolution and is better suited for studying cognitive processes like reading. D, a psychomotor test, is not directly related to measuring brain activity while reading.
