Quantitative measures of volume, length and biophysical parameters, specifically fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) of the two fiber tracts connecting the thalamus with the lateral orbitofrontal (lOFC) and medial orbitofrontal (mOFC) cortex. The symmetry index (SI) was estimated as follows: SI = (Left - Right) / 0.5 (Left + Right); STD = standard deviation.
