While Leo is performing a cognitive task, a researcher uses a physiological measure that scans various areas of his brain. In this case, the researcher is most likely using a(n):
A)electrocardiogram.
B)galvanic skin response.
C)functional MRI.
D)electromyogram.

Question

Quizplus · Accepted Answer

The physiological measure that scans various areas of Leo's brain is most likely a functional MRI (fMRI). An fMRI measures brain activity by detecting changes in blood flow and oxygenation in specific areas of the brain, providing a non-invasive way to visualize brain function. The other options listed (electrocardiogram, galvanic skin response, electromyogram) do not directly measure brain activity and are typically used to measure other physiological processes.
