What is the dead zone?

Answer 1

This term was used in Stephen King's book, "The Dead Zone" which was made into a movie starring Christopher Walken, later a tv series with Anthony Michael Hall. The dead zone refers to the part of the (human) brain that lies dormant because we haven't learned how to use it In the movie, the main character suffers from brain damage from a head injury and his brain rewires itself (we call it plasticity in the health field) to use other parts of the brain to compensate for the damaged parts.

Answer 2

The dead zone is an area in a body of water, typically the ocean, where oxygen levels are so low that marine life cannot survive. This oxygen depletion is often caused by excessive nutrient pollution, leading to algal blooms and subsequent oxygen depletion as the algae decomposes.
