The organization of visually-guided actions

我的研究项目调查了左右半球在视觉引导行动中的作用。了解每个大脑半球如何整合视觉信息并将其转化为目标导向的行动是理解人类大脑组织和功能原理的基础。提出了十项行为研究，其中右手和左手的右手和左手的个人将进行评估的视觉/和视觉任务。这些研究的动机是最近的发现表明，视觉转换抓取似乎是独特的每个大脑半球。这些研究被纳入三个主要的研究项目中，旨在回答以下问题：（1）在什么程度上和在什么条件下，左半球在处理与视觉-行动系统相关的视觉信息方面具有优势？(2)手/半球的差异是否存在于不同类型的抓握和不同成分的伸手抓握动作中？(3)两个半球的两个视觉系统之间的相互作用是否不同？通过了解每个大脑半球如何整合视觉和运动信息，这项研究有可能：1）解释左半球或右半球受损后出现的运动缺陷，2）开发针对这些患者的特定治疗方法，3）提供对利手起源的见解。

My research program investigates the roles of the right and the left hemispheres in the production of visually-guided actions. Understanding how each cerebral hemisphere integrates visual information and transforms it into goal-directed actions is fundamental to understanding the principles of human cerebral organization and function. Ten behavioural studies are proposed in which the right and left hands of right- and left-handed individuals will be assessed for visual/and visuomotor tasks. These studies are motivated by recent discoveries showing that visuomotor transformations for grasping appear to be unique to each cerebral hemisphere. The proposed studies are embedded within three major research projects aimed at answering the following questions: (1) To what extent and under what conditions are there left hemisphere advantages in processing visual information relevant to the vision-for-action system? (2) Do hand/hemispheric differences exist for different kinds of grasps and different components of the reach-to-grasp actions? (3) Are the interactions between the two visual systems different for the two hemispheres? By understanding how each cerebral hemisphere integrates visual and motor information, this research has the potential to: 1) explain motor deficits that appear after damage to the left or right hemispheres, 2) develop specific therapies tailored to those patients, and 3) provide insight into the origins of handedness.
