We know a lot about the functionality, structure, and mechanisms of human organs. Also, we know a lot about the brain's structure. But until now we don't know how it works. It consists of different types of neurons and glial cells. They are interconnected and communicate via electrical signals. But it is unclear where consciousness comes from. It is also crucial that we can't conclude from animal research on brains to human brains.

Every organism with a little higher complexity has the same three basic neurons: sensory, interneurons, and motor. The human brain consists of different parts: Thalamus, Hypothalamus, Amygdala, Cortex, etc. Each part has specific functions. The complex things are processed in the Cortex. The cells in the Cortex communicate via electrical signals in specific frequencies. The first theories of how the Cortex works said that each Cortex part has a specific function. Newer research shows that the brain is very flexible and plastic. Damages of the brain can be compensated by other brain areas which will take care of the functions. But that has to be trained.
