Naturally, neuroscientists look at the brain from the outside when measuring how the flow of information unfolds over space and time. A neuron, on the other hand, can only 'see' through its connections, and they are spatiotemporally limited. Hence, the neural processing hierarchy from the neuroscientist's perspective and the hierarchy from the perspective of individual neurons do not agree. In order to understand the brain, only the neurons' perspective matters, thus demanding a change in the neuroscientists' perspective.
神经科学家在测量信息如何在空间和时间上展开时,自然会从外部观察大脑。另一方面,神经元只能通过其连接“看到”,而它们在时空上是有限的。因此,从神经科学家的角度来看的神经处理层次结构和从单个神经元的角度来看的层次结构并不一致。为了理解大脑,只有神经元的视角才重要,因此需要改变神经科学家的视角。
