Selective attention is the process whereby a subset of the incoming sensory stream is selected for further processing. In the case of visual attention, this process can be subdivided into two distinct types of selection. The first type entails the establishment of a spatial focus, for preferential processing of a single, circumscribed area of the visual field as needed for object analysis or recognition. The second type involves the establishment of a filter which selectively enhances one or more distinct visual channels across the visual field as a whole, such as to facilitate perception of all stimuli of a specific color, spatial frequency, or direction of motion. The principal investigators will study the neurobiological mechanism of selective visual attention, through computer modeling of the correlates of attention at the single cell level and the integration of visual processing and attentional control at the systems level.

选择性注意是一个过程， 选择感觉流用于进一步处理。 的情况下 视觉注意，这个过程可以细分为两个不同的 选择的类型。 第一种类型需要建立一个 空间聚焦，用于单个， 视物所需的视野外接区域 分析或识别。 第二种类型涉及 建立选择性地增强一个或多个 在整个视野中有不同的视觉通道，例如 为了便于感知特定颜色的所有刺激， 空间频率或运动方向。 校长 研究人员将研究选择性的神经生物学机制。 视觉注意力，通过计算机建模的相关性， 注意力在单细胞水平和整合的视觉 系统层面的处理和注意力控制。
