Figure 3. Expertise in OP impacts amygdala activity.
a. Experts showed less anticipatory activity before pain than novices in an anatomically-defined amygdala cluster (t (13)=2.6, p<0.05). b. The linear temporal slope across blocks was lower for experts than novices in amygdala during anticipation. This indicates a gradual increase over time of anticipatory activity for novices only (t (13)=2.2, p<0.05). c. The anticipatory activity in the amygdala was positively correlated to the temporal slope across blocks in MCC (r=0.45, p< 0.05, for experts only r= 0.68, p<0.01 and for novices only r=0.14, p=0.6). * indicates p<0.05.
