This grant application seeks funds for the purchase of an MRI-compatible ERP measurement system. ERP (Evoked Response Potentials) and fMRI (functional Magnetic Resonance Imaging) are two brain imaging technologies that complement each other well, as the former provides good temporal resolution while the latter provides good spatial resolution. That is, ERP tells us when something is happening in the brain, while fMRI tells us where it is happening. Using them together will provide us with an excellent window into how the brain functions. The applicants currently have access to fMRI, but not to the kind of ERP instrumentation that can be used simultaneously with it. Therefore, we have sought funding to obtain it. This will complement our existing research capacities and give us a cutting-edge ability to do brain imaging research.

该赠款申请寻求资金用于购买 MRI 兼容的 ERP 测量系统。 ERP（诱发反应电位）和fMRI（功能磁共振成像）是两种相辅相成的脑成像技术，前者提供良好的时间分辨率，后者提供良好的空间分辨率。也就是说，ERP 告诉我们大脑中发生了什么事情，而 fMRI 则告诉我们事情发生在哪里。将它们结合使用将为我们提供了解大脑功能的绝佳窗口。申请人目前可以使用 fMRI，但无法使用可以与其同时使用的 ERP 仪器。因此，我们寻求资金来获得它。这将补充我们现有的研究能力，并赋予我们进行脑成像研究的尖端能力。
