Brain Imaging Showing Individual Differences

MRI of a brain with a bit of red and very little blue indicating where activity is taking place.

MRI of a brain very little red indicating where activity is taking place.

MRI of a brain with a great amount of red and a spec of blue indicating where activity is taking place.

These three functional magnetic resonance images (fMRI) show brain activity patterns of three different people performing the same simple, finger tapping task. The level of brain activity during performance of this task is designated using color. Blue indicates a low to moderate level of activity, red indicates a high level of activity, and yellow indicates an extremely high level of activity. As you can see, each of these three individuals shows a unique pattern of brain activation.
