The brain is the most important and complex part of the human body. Every action, decision, and behavior is a result of its function. However, our brain is not an independent entity and is surrounded by a mass of fibers that transmit information.

The most important of these is the brain stem, which is responsible for our core functions: perception, motor control, and the regulation of our body temperature.

The brain is divided into two main parts, the left and right. Each side is further divided into multiple regions. Each region has a specific role in the process of information transmission and the perception of external stimuli.

The first region on the left side is the input area. It receives information about the world and our place in it.
