This research assessed the accuracy of a widely-used automated cortical parcellation/labeling procedure compared to expert manual surface area measures for auditory cortex. Structural MRI brain scans of 50 healthy, right-handed, young adults were processed through a cortical reconstruction algorithm, yielding 3-dimensional cortical surface renderings. Manual measurements were taken directly on these renderings and compared to automated labels of several auditory cortex structures. Significant differences in cortical surface area were found. Important clinical and anatomical Implications will be discussed.
