项目摘要
DESCRIPTION (provided by applicant): Recent studies of human attention have uncovered a possible divide in the cortical areas underlying goal-directed attention and those underlying stimulus-driven reorienting of attention. The ventral frontoparietal system underlying stimulus-driven reorienting is of particular interest since it seems that damage to this system results in the syndrome of spatial neglect. Since many studies of this system take place in the macaque, our understanding of this frontoparietal system's role in attention will be greatly enhanced by understanding whether this model of attention generalizes to the macaque. I propose to perform a pair of experiments that will further our understanding of the homology between macaque and human frontoparietal systems underlying goal-directed control and stimulus-driven reorienting of attention. We will do this by classifying the degree of homology between the attention-related areas in both species according to function, topographic organization, and location. The results of these experiments will not only improve our understanding of the.attention system in both species, but will also serve as a guide to future fMRI and electrophysiological investigations of attention.
描述(由申请人提供):最近对人类注意力的研究揭示了目标导向注意力和刺激驱动的注意力重新定向的皮层区域的可能划分。刺激驱动的重新定向背后的腹侧额顶叶系统特别令人感兴趣,因为该系统的损伤似乎会导致空间忽视综合症。由于这个系统的许多研究发生在猕猴,我们的理解额顶叶系统的作用,注意力将大大提高了解这种模式的注意力是否推广到猕猴。我建议进行一对实验,将进一步我们的理解猕猴和人类额顶叶系统的同源性目标导向的控制和刺激驱动的注意力重新定位。我们将通过根据功能、地形组织和位置对两个物种的注意力相关区域之间的同源性程度进行分类来做到这一点。这些实验的结果不仅将提高我们对这两个物种的注意力系统的理解,而且还将为未来的fMRI和注意力的电生理学研究提供指导。
