For example, a person touches a hot stove and immediately our brain registers the pain and tells us to remove our hand. This is a survival mechanism. Not only does pain cause us to react, but the neurotransmitters released also serve to reinforce this behavior whenever we react by avoiding it (painful stimulus).
