N30R83 Brain Structures

The following 83 brain structures are covered the N30R83 atlas. The even label numbers denote left structures, the uneven numbers right structures.

Intersection with Gray Matter Probability Map

The definition of the cortical brain structures in N30R83 is not limited to the gray matter. In order to trim the VOIs to brain pixels with a high likelihood of belonging to gray matter, the VOIs can be intersected with a gray matter probability mask thresholded at a certain probability level. It has been noted that this masking tends to excessively reduce the area of the central structures. Therefore, PNEURO offers the option to exclude the central structures from the intersection process. As the ventricular regions have no relation to the gray matter, they are always disregarded by the intersection.
