Hello everyone,
I'm working on a group analysis of cortical thickness, surface area, curvature and sulcal depth with FreeSurfer 5.3. However I'm in trouble concerning the interpretation or the meaning of my results, especially concerning curvature and sulcal depth.
I understood that curvature can be positive when it concerns sulcus or positive in case of gyrus. According to my result it would be almost the same for sulcal depth. The value of sulcal depth is positive on a sulcus while it is negative on a gyrus.
Am I correct?
All the best,
Damien Marie
