The cortical visual system consists of many richly interconnected areas. Each area is characterized by more or less specific receptive field tuning properties. However, these tuning properties reflect only a subset of the interactions that occur within and between areas. Neuronal responses may be modulated by perceptual context or attention. These modulations reflect lateral interactions within areas and feedback from higher to lower areas. Recent work is beginning to unravel how horizontal and feedback connections each contribute to modulatory effects and what the role of these modulations is in vision. Whereas receptive field tuning properties reflect feedforward processing, modulations evoked by horizontal and feedback connections may reflect the integration of information that underlies perception.
皮质视觉系统由许多相互连接紧密的区域组成。每个区域都具有或多或少特定的感受野调谐特性。然而，这些调谐特性仅反映了区域内部和区域之间发生的相互作用的一个子集。神经元反应可能会受到感知背景或注意力的调节。这些调节反映了区域内的侧向相互作用以及从高级区域到低级区域的反馈。最近的研究开始揭示水平连接和反馈连接各自如何对调节效应做出贡献，以及这些调节在视觉中起什么作用。感受野调谐特性反映前馈处理，而水平连接和反馈连接引起的调节可能反映了构成感知基础的信息整合。
