Figure 8. Correlation between the P₁₀₀ amplitude in pattern-reversal visual evoked potential (PR-VEP) and the activation of cortical neurons. A: Opposite hemicerebrum; B: Homonym hemicerebrum. The bilateral cortical mean percent change of the blood oxygen level–dependent functional magnetic resonance imaging (BOLD-fMRI) was significantly correlated with the P₁₀₀ amplitude in VEP, in the contralateral and the ipsilateral Brodmann area (BA).
