在这项研究中，我们测试是否有一个躯体感觉组织在人类前扣带皮层（ACC）和补充运动区（SMA），作为运动控制的中枢反馈感觉加工的反映。为此目的，15名正常青年人在无痛和疼痛的电刺激正中神经在手腕和胫神经在内踝进行了fMRI记录。结果表明，与胫神经区相比，正中神经区在ACC中的表现更靠前，在SMA中的表现更靠后。这对于无痛和疼痛刺激强度都是正确的。这些结果表明人ACC和SMA的躯体感觉组织。(c)2006年爱思唯尔公司All rights reserved.
In this study, we tested whether there is a somatotopic sensory organization in human anterior cingulate cortex (ACC) and supplementary motor area (SMA), as a reflection of central feed-back sensory processing for motor control. To this aim, fMRI recordings were performed in 15 normal young adults during nonpainful and painful electric stimulation of median nerve at the wrist and tibial nerve at the medial malleolus. Results showed that the representation of median nerve area was more anterior in the ACC and more inferior in the SMA than the one of tibial nerve area. This was true for both nonpainful and painful stimulation intensities. These results point to a somatotopic sensory organization of human ACC and SMA. (c) 2006 Elsevier Inc. All rights reserved.
