Figure 9. Discharge of anterior cingulate cortex (ACC) neurones in response to thermal stimulation.

Figure 9

Data from CRD-excited neurones in sham-treated and EA rats (seven neurones per group) that were activated by transcutaneous electrical stimulation. Application of water at 40°C to the hindpaw produced no measurable electrophysiological effect. ACC neurones in sham-treated and EA rats increased their discharges in response to the application of thermal stimulation within the noxious range (46°C–52°C). Note that basal firing rates were significantly higher in EA rats compared with sham-treated rats. However, proportional increases in ACC firing rates in response to thermal stimulion were not significantly different between sham-treated and EA rats. *P < 0.05 compared with sham-treated rats.
