Without giving it too much thought, we might assume being unconscious is a little like flicking a switch, turning off our awareness by shutting down key areas of our nervous system.
Summary: Researchers investigate how brain networks fragment while under a variety of unconscious states. Source: University of Michigan. When patients undergo major surgery, they’re often put under anesthesia to allow the brain to be in an unconscious state.

When a person is unaware of their surroundings and unable to respond, this is described as being unconscious. Unconsciousness is a medical emergency, and it is often a sign of a serious health issue that could result in death or permanent disability.
