Desmurget et al. (Reports, 8 May 2009, p. 811) applied direct electrical stimulation (DES) to the human cortex to study the origin of movement intention. Their interpretation assumed that DES causes cortical activation, whereas it is possible that it actually evokes deactivation. The lack of certain knowledge about the true effects of DES limits its use for validation of cognitive models.
德斯穆尔热等人(报告,2009 年 5 月 8 日,第 811 页)应用直接电刺激(DES)于人类大脑皮层以研究运动意图的起源。他们的解释假定 DES 引起皮层激活,而实际上它也可能引起去激活。由于对 DES 的真实效果缺乏某些了解,限制了其在验证认知模型中的应用。
