年龄：13-14 岁 为了研究大脑，科学家可以使用称为 MRI（磁共振成像）扫描仪的机器。核磁共振扫描仪以安全的方式拍摄大脑的照片，使科学家能够了解大脑的结构及其功能。 MRI 可以帮助科学家了解当您从事不同的活动（例如阅读这样的句子）时，大脑的哪些区域处于活跃状态！首先，本文解释了 MRI 扫描仪如何安全地拍摄高质量的大脑图像。接下来，我们将解释 MRI 扫描仪如何通过测量大脑不同部位的活动来帮助科学家了解大脑的功能。最后，我们描述了参与涉及 MRI 扫描仪的研究的感觉，以及科学家使用 MRI 扫描仪作为工具可以回答的各种问题。
AGES: 13–14 To study the brain, scientists can use a machine called an MRI (magnetic resonance imaging) scanner. An MRI scanner takes pictures of the brain in a safe way, allowing scientists to learn about the structure of the brain and its functions. MRI helps scientists learn which areas of the brain are active when you engage in di erent activities, such as reading a sentence like this one! First, this article explains how theMRI scanner safely takes high-quality pictures of the brain. Next, we will explain how the MRI scanner can help scientists learn how the brain functions by measuring activity in di erent parts of the brain. Finally, we describe what it is like to participate in a study involving the MRI scanner and the kinds of questions scientists can answer using the MRI scanner as a tool.
