认知和系统神经科学的一个核心挑战是将动物极其复杂的行为与它们同样复杂的大脑活动联系起来。最近描述的大规模神经模型并没有弥合神经活动和生物功能之间的差距。在这项工作中，我们提出了一个250万个神经元的大脑模型（称为“Spaun”），通过展示许多不同的行为来弥补这一差距。该模型仅以视觉图像序列呈现，并通过物理建模手臂绘制其所有响应。虽然简化了，但该模型捕获了神经解剖学，神经生理学和心理行为的许多方面，我们通过八个不同的任务来证明。
A central challenge for cognitive and systems neuroscience is to relate the incredibly complex behavior of animals to the equally complex activity of their brains. Recently described, large-scale neural models have not bridged this gap between neural activity and biological function. In this work, we present a 2.5-million-neuron model of the brain (called "Spaun") that bridges this gap by exhibiting many different behaviors. The model is presented only with visual image sequences, and it draws all of its responses with a physically modeled arm. Although simplified, the model captures many aspects of neuroanatomy, neurophysiology, and psychological behavior, which we demonstrate via eight diverse tasks.
