NEURAL BASIS OF RESPONSE SELECTION

描述(申请人摘要)：本项目将调查 使用功能磁共振成像(FMRI)选择反应的神经基础。 功能成像在认知领域发挥着越来越重要的作用 神经科学研究，包括记忆、视觉和运动 控制力。拟议的实验是一种尝试，目的是将行为学 并使用一种名为 侧翼任务侧翼任务已被证明在行为上能唤起反应 选择不会引起明显反应的刺激的过程。一个 开发了分离这些选择的神经基因座的程序 并检查它们对刺激特性的敏感性。使用 这种新的方法，重新认识了选择之间的相互作用 可以创造注意力和反应的竞争。

DESCRIPTION (Applicant's abstract): This project will investigate the neural basis of response selection using functional magnetic imaging (fMRI). Functional imaging is playing an increasingly significant role in cognitive neuroscience research, including the topics of memory, vision and motor control. The proposed experiments are an attempt to integrate behavioral and imaging findings in these three areas using a paradigm called the flanker task The flanker task has been shown behaviorally to evoke response selection processes for stimuli that do not elicit an overt response. A procedure is developed to isolate the neural loci of these selection processes and to examine their sensitivity to stimulus properties. With this new method, a new understanding of the interaction between selective attention and response competition can be created.
