Abstract

The magnitude of neural responses in sensory cortex depends on the intensity of a stimulus and its probability of being observed within the environment. How these two variables combine to influence the overall response of cortical populations remains unknown. Here we show that, in primary visual cortex, the vector magnitude of the population response is described by a separable power-law that factors the intensity of a stimulus and its probability.

摘要

感觉皮层中神经反应的强度取决于刺激的强度及其在环境中被观察到的概率。这两个变量如何结合起来影响皮层群体的整体反应仍然未知。在这里，我们表明，在初级视觉皮层中，群体反应的向量大小由一个可分离的幂律描述，该幂律将刺激的强度及其概率进行了分解。
