I've heard that the human brain is the most complex organ in the body. How do scientists study the brain?

Scientists study the brain by using a combination of techniques, including neuroimaging, electrophysiology, and genetics. Neuroimaging involves taking pictures of the brain while it is working, which can be used to look at how different parts of the brain are connected and how they work together. Electrophysiology involves recording electrical activity in the brain, such as the firing of neurons. Genetics involves studying the genes that are expressed in the brain. By combining these techniques, scientists can gain a better understanding of how the brain works.
