We are currently using FreeSurfer to measure several dimensions of cortical anatomy in our data set including cortical thickness, volume, sulcal depth, and gyrification, across the entire cortex, as well as within parcellated areas. We will then examine correlations of the neuroanatomical variations with individual differences in reading and language ability. Below are several representations of the left hemisphere of a 21-year old male participant produced by FreeSurfer. The pial surface is shown on the left, and the “inflated” hemisphere on the right. The inflated hemisphere allows visualization of the cortex that is buried in sulci. In the first row, the parcellated hemispheres are color-coded to reflect various anatomical regions. In the second row, variations in cortical thickness are displayed. The third row displays sulcal depth.
