The brain sends and receives information from 86 billion neurons, communicating through complex circuits.
This enables us to walk, breathe, think, and everything in between.
This communication system is called the Nervous System.
The Nervous System communicates with many systems in our bodies, such as the gastrointestinal system, which allows us to digest the food we eat.
Certain disorders cause the Nervous System to malfunction, disabling its ability to communicate with some bodily functions.
