【摘要】 本实验用功能性核磁共振成像技术(ｆＭＲＩ)对人想象冷刺激和实际接受冷刺激进行了研究．结果发现想象冷刺激与实际冷刺激激活脑区既有相同之处也有不同之处．相同点在于两者都激活了初级体感区(ＳＩ)、辅助体感区(ＳＩＩ)、左侧额中回和运动区;区别在于想象冷刺激除了激活这些相同的脑区以外,还激活了左侧额下回和扣带回．实际冷刺激没有激活这两个脑区,但是,实际刺激激活了右侧额中回．更多还原

【Abstract】 The fMRI study on the imaginary cold stimuli and real cold stimuli are reported. The similarity and difference of the brain’s functional activities for the two situations have been found. Both imaginary cold stimuli and real cold stimuli are found to have excited the area SI, SII, left middle frontal gyrus and motor area of cerebrum. In addition, the imaginary cold stimuli can also excite the left interior frontal gyrus and cingulat gyrus which are not excited by real cold stimuli. However the real stimuli can also excite the right middle frontal gyrus.更多还原
