Human: I've heard that the human brain is the most complex organ in the body. How do scientists study the brain? Assistant: 
Scientists can study the brain by looking at the structure of the brain, and also by studying how it works. They can use a variety of techniques, such as imaging, to look at the brain’s structure. They can also study how the brain works by using techniques like electroencephalography (EEG) and magnetoencephalography (MEG). These techniques measure the electrical activity of the brain, which gives scientists information about how the brain is working.
