Computer-generated image of a human brain shows activation in response to various sound frequencies

In this computer-generated image of a human brain, surface convolutions have been flattened out, allowing scientists to more accurately measure the brain's geometric and anatomical properties. The brightly colored regions show activation of the primary auditory cortex in response to various sound frequencies. To obtain the image, researchers used ultrahigh-field magnetic resonance imaging (MRI), with a magnetic field strength of 7 tesla, which provides highly detailed information about brain structure and function.
