In
this study, the connection between the bilateral STGs in normal controls (NC)
and schizophrenics (SZ) is investigated using DTI measures, namely FA, mode
and trace. The connection was obtained from whole-brain streamline
tractography using STGs white matter as ROIs. By dividing the connection into
three sub-regions (Left, Corpus Callosum and Right) and comparing the
computed DTI measures of NC and SZ, we found statistically significant
differences in mean FA and mode in the Right region, with NC having greater
values. This study paves the way for further localization of the differences
in STGs connection between NC and SZ.
