当前神经科学的一个主要挑战是阐明认知功能背后的大脑机制。 毫无疑问，大脑中的认知处理涉及大量细胞。本文通过结合人类受试者的心理学研究和行为猴子运动皮层神经元群的神经生理学研究，探讨了研究这些问题的逻辑。获得的结果表明，随时间变化的心理过程可以在神经元群体随时间变化的活动中可视化。此外，运动皮层中细胞之间的功能相互作用与在执行相同计算的大规模互连人工网络中观察到的功能相互作用非常相似。
A major challenge of current neuroscience is to elucidate the brain mechanisms that underlie cognitive function. There is no doubt that cognitive processing in the brain engages large populations of cells. This article explores the logic of investigating these problems by combining psychological studies in human subjects and neurophysiological studies of neuronal populations in the motor cortex of behaving monkeys. The results obtained show that time-varying psychological processes can be visualized in the time-varying activity of neuronal populations. Moreover, the functional interactions between cells in the motor cortex are very similar to those observed in a massively interconnected artificial network performing the same computation.
