Fig. 2.

Significant negative correlation between the line bisection error (mm) and V1 cortical thresholds as measured by TMS. Subjects with lower visual cortical TMS thresholds (i.e. more excitable visual cortex) demonstrated greater shifts during the line bisection task to the right of the true center (i.e. positive line bisection error). In contrast, those individuals that were more right hemisphere dominant as reflected by a more negative line bisection error had higher visual cortical thresholds (i.e. lower cortical excitability).
