Figure 4. Average response properties for three brain regions that showed best specificity for DMA.

Figure 4

Left bar graphs indicate task dependence, where responses are shown during touch that induced DMA pain (A), non-painful touch (T), and visual bar ratings (V). All three areas show statistically significantly higher responses during DMA. Next bar graphs show responses during DMA at three treatment sessions (session 1: prior to Lidocaine treatment; 2: after a 6-hour treatment; and 3: after 2-week treatment). There were no significant treatment effects. Left scatter-grams indicate the relationship between DMA and regional activity, positively correlated in all three areas. Right scatter-grams show the relationship between visual ratings and brain activity. Asterisks indicate significance at P < 0.01; regression plots show 95% confidence interval.
