TRAINING ON FMRI COMPATIBLE EYE TRACKER IN THE 3T SCANNER ROOM

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 这项提议的目的是让研究人员在监测受试者眼睛的同时获得MRI数据。首先，眼动追踪是许多研究的必要实验对照。通过监测参与者的眼睛，研究人员可以确保眼球运动的差异不会导致归因于感知和认知的fMRI信号的差异。将眼动追踪和功能磁共振成像结合起来的第二个原因，也许是它允许研究人员解决的新研究问题。 目前，CMRR的3 T扫描室中的眼动仪使用不多。主要原因是很少有人知道如何使用它，而且学习的时间投资很高。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The aim of this proposal is to allow researchers to monitor subjects' eyes while simultaneously acquiring MRI data. First, eye tracking is a necessary experimental control for many studies. By monitoring participants' eyes, the researcher can make sure that eye movement differences are not causing differences in the fMRI signal that are attributed to perception and cognition. A second, perhaps stronger reason for combining eye tracking and fMRI are the new research questions it allows investigators to address. Currently, the eye tracker in the 3T scanner room at CMRR is not used much. The main reason being that very few people know how to use it, and the time investments for learning are high.
