皮层中的连通性在多个尺度上组织（1-5），这表明依赖于尺度的相关活动对于理解感觉皮层的行为及其在刺激编码中的功能尤为重要。我们利用最大熵模型（6-9）分析了麻醉猕猴（Macaca mulatta）初级视觉皮层的多个四极体记录，分析了皮层相互作用的尺度依赖结构。我们比较了局部神经元簇(
Connectivity in the cortex is organized at multiple scales(1-5), suggesting that scale-dependent correlated activity is particularly important for understanding the behaviour of sensory cortices and their function in stimulus encoding. We analysed the scale-dependent structure of cortical interactions by using maximum entropy models(6-9) to characterize multiple-tetrode recordings from primary visual cortex of anaesthetized macaque monkeys (Macaca mulatta). We compared the properties of firing patterns among local clusters of neurons (
