The brain could be compared to a power plant that emits and receives signals throughout the day and night. The nervous system communicates with different parts of the body to maintain homeostasis as well as keep a good balance between the body and mind. These electric waves coordinate movement, breathing, pain, hunger, satiety, memory, concentration, impulsiveness, anger, joy, sadness, and so on.
