讲座内容：
Since neural resources are severely limited, efficiently processing visual information requires selecting only a very small fraction of the multitude of information available to the visual system at any one instant in time. Attentional selection is the main mechanism that controls this selection process. In this talk, I will discuss my two studies examining the neural mechanisms of attentional selection: the saliency map and feature binding. First, the bottom-up contribution to the allocation of exogenous attention is a saliency map, whose neural substrate is hard to identify because of possible contamination by top-down signals. I will present how my first work obviates this possibility and suggests the bottom-up saliency map is created in V1. Second, I will show a color-motion misbinding developed by Wu et al. (Nature 2004), and my recent work using this illusion that provides strong and direct evidence for active feature binding in early visual cortex and for a critical role of reentrant connections from specialized intermediate areas to early visual cortex in this process. Finally, I will discuss how human early visual cortex plays an important role in the saliency map and feature binding, challenging the dominant view that the bottom-up control of attention is generated in frontoparietal networks.

讲座内容：
One fundamental question in brain research is that how our perceptual and cognitive functions can be effectively enhanced so that human brain is capable of performing more complex tasks. Fortunately, recent advances in brain training shed new light on this line of research. In this talk, I’ll present an overview of my research on two regimes of brain training– perceptual learning, which refers to the improved performance by repeated practice on a simple visual task, and action video game play, a ubiquitous social activity in modern society. Specifically, I’ll demonstrate that how my recent psychophysical work challenges conventional models of perceptual learning and how learning enables our visual system to flexibly arrange internal resources. Then, I’ll also briefly introduce the history of research on perceptual and cognitive consequences of action video game play, particular in the domain of vision and memory. Finally, I will discuss implications for the potential role of behavioral training in rehabilitative or protective regimens, such as aging, ADHD, amblyopia etc.
