Italian and Norwegian researchers have show, via brain imaging, how people Narcolepsy experience humor differently than neurotypical people. Ever since Narcolepsy was first identified in 19th century, neurologists have observed that amusement or other positive emotions can trigger distinctive symptoms of disorder. This symptom is called or temporary muscle weakness. Full - body cataplexy may make someone but it can also be more subtle, affecting just legs, arms, or face. Narcolepsy develops as result of autoimmune on brain circuits that regulate sleep and wake. Cataplexy is thought to come from paralysis that accompanies REM Sleep, usually keeps people from acting out their dreams. In people with Narcolepsy, paralysis seems to over into waking time. They remain and aware while cataplexy occurs. Studying cataplexy helps us understand connections between parts of brain that regulate emotions and REM Sleep. University of Bologna neurologists have been having children and with Narcolepsy watch short movies - Roadrunner and Coyote cartoons or YouTube cat videos, for example. They ask study participants to choose between few funny videos. For each, video that worked well was shown while young subjects were EEG electrodes and inside MRI scanner. This complicated arrangement was needed to observe cataplexy in setting where it could be record. In 2019 paper in Neurology, Anna Elisabetta Vaudano and her colleagues report that young people with Narcolepsy have broader pattern of metabolic activity lighting up brain when they laugh, but do not experience cataplexy. For example, motor cortex, part of cortex responsible for controlling voluntary movement, is activated more than in healthy controls. I asked Vaudano whether this finding meant that these young people were trying to exert deliberate control over their cataplexy events sort of like sensing and holding back sneeze, but something more powerful. Answer Is Not Straightforward, She Say. Interviewing people with Narcolepsy reveals that some can use tricks to avoid cataplexy - thinking of something else or tensing their muscles, but Bologna team was asking their young subjects to just let it happen. In their paper, authors speculate that their participants - newly diagnosed and unmedicated - are adopting precocious, unconscious strategies to inhibit cataplexy occurrence. Vaudano point out that one region of brain called zona incerta was only activated during laughter in people with Narcolepsy, not in controls. Research on zona incerta in animals suggests that it also helps control fear - associate behavior even when they do experience cataplexy, It appears that people with Narcolepsy respond differently to humor. In another recent paper published in Sleep, Norwegian researchers asked people with Narcolepsy and their healthy to watch movie clips that include joke punchline,s and had study participants rate movie clip they saw. Mri showed no differences in brain activation between patients and controls for movies thought were funny. For clips without punchlines, there was no difference.
