Lau HC 《The American psychologist》2007,62(7):686-8; discussion 689-91
The author has previously claimed that neural activity in a medial frontal brain area represents conscious motor intentions. A. Machado and F. J. Silva attempted to challenge this claim by arguing that such intentions are not necessarily causally effective and must be caused by something else, so that they therefore cannot be the unmoved first movers in action. The author's reply is that he made no such claims about the causal status and origin of conscious intentions. In fact, he has elsewhere presented empirical evidence in support of the idea that intentions are not necessarily causal. But this does not stop researchers from studying the neural basis for the conscious impression that one intends and wills one's actions. One can feel and attend to such intentions, be they causal or not. The author's claim is that there is neural activity in the medial frontal wall that reflects such conscious feelings. Other recent empirical evidence that supports this view is described. 相似文献
