855 - How do scientists study the brain?

Scientists use various ways to study the brain, including:

1. Imaging tests: Special machines like MRIs and CT scans take pictures of the brain to see what's happening inside.
2. Brain wave tests: They use special headbands to measure the electric signals (brain waves) that our brain sends.
3. Blood flow tests: They check how blood flows to different parts of the brain to see which areas are working.
4. Dissection and microscopes: They examine the brain's structure under a microscope to learn about its tiny parts.
5. Psychological tests: They ask people to do tasks and answer questions to see how their brain works.

All these methods help scientists learn more about how our brain works and how to keep it healthy.
