LaToya hypothesizes that there are differences in brain anatomy between musicians and nonmusicians. Which technique is LaToya most likely to use to test her hypothesis regarding brain anatomy?

EEG measures electrical activity in the brain through electrodes placed on the scalp. While it provides valuable information about brain function and activity, it does not offer detailed anatomical images, making it unsuitable for examining structural differences between groups.

MEG detects magnetic fields generated by neuronal activity, providing insights into brain function and timing of neural events. However, similar to EEG, it focuses on functional aspects rather than structural differences, making it less appropriate for LaToya's hypothesis on brain anatomy.

PET scans provide images of brain activity by detecting radioactive tracers, showing metabolic processes rather than structural anatomy. While PET can reveal functional differences, it does not directly assess anatomical variations, which is LaToya's primary interest.

fMRI measures brain activity by detecting changes in blood flow, linking function to structure. However, it is more focused on how the brain functions rather than providing the high-resolution images of anatomy that LaToya needs to compare structural differences.
