Abstract：
Predictive remapping of receptive fields (RFs) is thought to be one of the critical mechanisms for enforcing perceptual stability during eye movements. While RF remapping has been observed in several cortical areas, its role in early visual cortex and its consequences on the tuning properties of neurons have been poorly understood. Here, we track remapping RFs in hundreds of neurons from visual area V2 while subjects perform a cued saccade task. We find that remapping is widespread in area V2 across neurons from all recorded cortical layers and cell types. Furthermore, our results suggest that remapping RFs not only maintain but also transiently enhance their feature selectivity due to untuned suppression. Taken together, these findings shed light on the dynamics and prevalence of remapping in the early visual cortex, forcing us to revise current models of perceptual stability during saccadic eye movements.
摘要：
接受野（RF）的预测性重映射被认为是在眼球运动期间增强感知稳定性的关键机制之一。虽然已经在几个皮质区域观察到RF重新映射,它在早期视觉皮层中的作用及其对神经元调谐特性的影响一直知之甚少。这里,当受试者执行提示扫视任务时，我们从视觉区域V2跟踪数百个神经元中的重新映射RF。我们发现，在所有记录的皮质层和细胞类型的神经元中，区域V2中的重映射很普遍。此外，我们的结果表明,由于未调节的抑制,重新定位的RFs不仅维持了特征选择性,而且暂时增强了特征选择性.一起来看,这些发现揭示了早期视觉皮层重新映射的动态和普遍性，迫使我们在扫视眼球运动期间修改当前的感知稳定性模型。
