Figure 7.

This is an example of how a high model order analysis can split components obtained from a low model order analysis and improve the definition of the connected region. The component IC6 (right hemisphere, and leftmost plot) and IC12 (left hemisphere, and rightmost plot) are from low order analysis. They cover uncinate fasciculus and parts of the inferior fronto‐occipital fasciculus. The corresponding high order analysis components (shown in the middle) are IC10, IC14, IC58 (right hemisphere) and IC12, IC42, IC78 (left hemisphere). They clearly demonstrate the splitting of the low model order component, and the better definition of the hook‐shape of uncinate fasciculus as captured by the high order components IC10 and IC12.
