Figure 2From: Cuneus and fusiform cortices thickness is reduced in trigeminal neuralgiaGroup differences in cortical thickness between TN patients and controls. Blue regions indicate areas showing thickness reduction and red regions indicate thickness increase in TN patients when compared to controls at a threshold p < 0,01, uncorrected. It was observed cortical thickness changes in areas that include orbitofrontal cortex, insula, motor cortex, anterior cingulate gyrus and temporal lobe. All these regions, involved in supraspinal nociceptive processing, show grey matter alterations in different types of chronic pain.Back to article page
