I'm interested in learning more about how the brain works.

The human brain is a complex organ that contains billions of cells and trillions of connections between them. It's made up of many different parts, including the cerebrum (the largest part), the cerebellum (which helps control muscle movement), and the limbic system (which controls emotion). The cerebral cortex is the outer layer of the brain and it is responsible for higher cognitive functions such as memory, language, and thought.
