History of neuroimaging

Neuroimaging is a way of looking at the brain by taking pictures. It helps scientists study the structure and activity of the brain. The history of neuroimaging goes back hundreds of years. In the late 1700s, scientists used electricity to try to look at the brain. But they weren't able to take pictures until the 1800s. People like Emil du Bois-Reymond used magnets and waves to map out how neurons were arranged in the brain. In the early 1900s, X-rays were used to look at the brain. Then, in the 1950s, scientists used a machine called a computerized tomography (CT) scanner to get a better picture. After that, people used magnetic resonance imaging (MRI) which uses magnets and radio waves to create detailed pictures of the brain. Today, there are many more ways to image the brain and scientists can better understand how it works.
