So it seems possible that the neurobiology for helpless, involuntary laughter, like my parents lying on the floor screaming about a silly song, might have a different basis to it than some of that more polite social laughter that you encounter, which isn't horrible laughter, but it's behavior somebody is doing as part of their communicative act to you, part of their interaction with you; they are choosing to do this.
E posibil ca neurobiologia râsului involuntar, ca cel al părinţilor mei care hohoteau la un cântec stupid, să difere de râsul politicos, social, care nu-i oribil, ci e doar felul în care cineva comunică cu tine, parte a interacţiunii dintre voi, o alegere conştientă.
