<b>Contrast response function of adapted neural populati</b>

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. The published datasets 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. These data are described in Tring et al, "On the contrast response function of adapted neural populations," published in <i>J.Neurophysiol</i>, 2024.

感觉皮层（sensory cortex）的神经响应幅度，由刺激强度及其在环境中被观测到的概率共同决定。目前学界尚未明确这两个变量如何联合作用，从而影响皮层神经元群体的整体响应。已公开的数据集表明，在初级视觉皮层（primary visual cortex）中，群体响应（population response）的矢量幅度（vector magnitude）可通过可分离幂律（separable power-law）模型刻画，该模型可将刺激强度与出现概率进行因子化分离。上述数据来自Tring等人2024年发表于《J.Neurophysiol》的论文《适应性神经群体的对比度响应函数》（On the contrast response function of adapted neural populations）。
