While the term "gelotology" is sometimes used to refer to the study of laughter, it's not a formally established scientific discipline.

Laughter is studied in various fields, including:

* Psychology: Examines the psychological effects of laughter, its role in social interactions, and its relationship to mood and well-being.

* Neuroscience: Studies the brain mechanisms involved in laughter, including the neural pathways and areas activated during laughter.

* Sociology: Investigates the cultural and social aspects of laughter, including its use in different societies and contexts.

* Linguistics: Analyzes the language of humor and laughter, including the use of puns, jokes, and other forms of verbal humor.

Therefore, while "gelotology" might be a catchy term, it's not a recognized field of science. Laughter is studied within various existing disciplines.
