明尼苏达大学的神经学家发现大脑皮层的运动区有思维功能。从１９９３年起，他们开始训练猴子，让猴子在一定时间内完成一项需要记住事件次序的任务。训练中，让猴子看屏幕上一个跳动的黄点，这个点按随机而不显示次序的方式进行循环跳动。三到四次循环后，跳动的一个点会变成 Neuroscientists at the University of Minnesota have found that motor zones in the cerebral cortex have a mental function. Since 1993, they have started training monkeys to allow monkeys to complete a task within a certain period of time that requires memorizing the order of events. During the training, let the monkey see a beating yellow dot on the screen, and this clicks randomly and without displaying the order to cycle. After three or four cycles, a point of beating will become
