What is the scientific explanation for laughter?

Answer 1

Laughter is a verbal neurological response to a positive mood. The limbic system is partly responsible for laughter occurring. The limbic system is a primitive part of the brain that regulates emotions, and aids with basic functions that are required for survival.

Answer 2

Laughter is a complex neurological response to certain stimuli that activates various regions of the brain, including the prefrontal cortex, limbic system, and motor cortex. It is believed to have evolved as a social behavior to promote bonding and communication among individuals, as well as to relieve stress and tension. The act of laughing triggers the release of endorphins, dopamine, and other feel-good neurotransmitters, producing the positive feelings associated with laughter.
