The third major theory around the purpose of yawning is the arousal hypothesis. The arousal hypothesis states a major function of yawning is the regulation of levels of rest and arousal, involving the previously mentioned DMN. | The third major theory around the purpose of yawning is the arousal hypothesis.

The brain-cooling hypothesis is another theory of yawning, based on observing that thermoregulation problems and abnormal yawning tend to go together. Yawning also tends to be associated with some diseases and medications. | The brain-cooling hypothesis is another theory of yawning, based on observing that thermoregulation problems and abnormal yawning tend to go together.

What happens in this situation is that Yawnie attempts to trigger a yawn. However, another node sends a different signal about lighting problems. The receiver of both signals then pipes the action elsewhere to trigger a sneeze instead of a yawn. This redirection behavior is not an active decision-making process. It is programmed in the node’s default instructions. | What happens in this situation is that Yawnie attempts to trigger a yawn.
