扣带皮层（CC）处理阶段性疼痛开始于尾部。这通过脑电源分析（BESA（R））和电流重建成像（CURRYR）来证明，所述脑电源分析（BESA（R））和电流重建成像（CURRYR）识别个体脑形态中的激活的神经元集合，包括用于体积电流计算的边界元方法。从30名受试者中获得数据，这些受试者在重复的会话中，对太阳穴、手和脚施加红外激光刺激，或对指尖施加皮内电击。CC活动开始于约230 ms（+/- 20 ms;受试者间SD。）位于CC中部或后部，一般位于Brodmann 23区（受试者内SD < 5 mm;受试者间SD < 15 mm），与伤害性刺激的种类和身体部位无关。(C)2004爱思唯尔爱尔兰有限公司保留所有权利。
Cingulate cortex (CC) processing of phasic pain starts in caudal parts. This is evidenced by electrical brain source analysis (BESA(R)) and current reconstruction imaging (CURRYR) which identify the activated neuronal assemblies in the individual brain morphology, including the boundary element method for volume current calculation. Data were obtained from 30 subjects who experienced, in repeated sessions, infrared laser stimuli applied on temple, hand, and foot, or electrical shocks applied intracutaneously on finger tip. CC activity started around 230 ms (+/- 20 ms; inter-subject SD.) and was localized in mid or posterior CC, in general in Brodmann's area 23 (intra-subject SD < 5 mm; inter-subject SD < 15 mm), independent of the kind and body site of noxious stimulation.
