Vores hjerner er fantastiske, komplekse organer. Millioner af \u00e5rs evolution har gjort dem til mestre i multitasking, hvilket giver os mulighed for at g\u00f8re forskellige ting p\u00e5 samme tid. Lad os sige, at du er ude at g\u00e5 en tur, og samtidig beslutter du dig for at sende en sms til en ven. Det lyder simpelt, men din hjerne skal styre din krop, s\u00e5 du forts\u00e6tter med at g\u00e5; vide, hvor du er; forhindre dig i at falde; betjene din telefon; skrive din besked; og meget mere!<\/p>\n<\/div>\n

En af grundene til, at vores hjerne er s\u00e5 god til at udf\u00f8re flere opgaver p\u00e5 \u00e9n gang, er, at den bruger dele af vores krop, der tilsammen kaldes det vestibul\u00e6re system. Det er et helt s\u00e6t af sanser og organer, der hj\u00e6lper os med at udf\u00f8re komplekse opgaver \u2013 som f.eks. at g\u00e5 og skrive sms\u2019er! For eksempel er vores indre \u00f8rer en del af det vestibul\u00e6re system. De sender information til hjernen, som hj\u00e6lper os med at holde balancen og kontrollere vores kroppe, s\u00e5 vi ikke bliver svimle og falder. Vi har dog fundet ud af, at v\u00e6gtl\u00f8sheden i rummet forvirrer vores vestibul\u00e6re systemer!<\/p>\n

En gruppe frivillige har fl\u00f8jet med et specielt fly, der kaldes Zero-G-flyet. Ved at stige og dykke p\u00e5 en bestemt m\u00e5de oplever passagererne ombord et frit fald, der f\u00f8les som v\u00e6gtl\u00f8shed. Zero-G-flyet kan g\u00f8re passagererne v\u00e6gtl\u00f8se i 20 sekunder, f\u00f8r det er n\u00f8dvendigt at tr\u00e6kke op igen, men det er tid nok til at gennemf\u00f8re videnskabelige eksperimenter!<\/p>\n

De frivillige ombord p\u00e5 Zero-G-flyet fik udleveret virtual reality-briller, der gav dem fornemmelsen af at befinde sig inde i en labyrint. Under deres 20 sekunder lange perioder med v\u00e6gtl\u00f8shed skulle de finde vej gennem labyrinten for at finde en guldm\u00f8nt. De frivillige fandt dette langt sv\u00e6rere i v\u00e6gtl\u00f8shed end da de var tilbage p\u00e5 jorden!<\/p>\n

Eksperimentet var m\u00e5ske sjovt, men det giver anledning til nogle alvorlige bekymringer. De frivilliges vestibul\u00e6re systemer blev forvirret af v\u00e6gtl\u00f8sheden, hvilket ogs\u00e5 er det, der sker med astronauter i rummet. Hvis vi sender mennesker ud p\u00e5 lange rejser til andre planeter, vil de v\u00e6re v\u00e6gtl\u00f8se i lang tid. Dette vil g\u00f8re det sv\u00e6rere for dem at udf\u00f8re opgaver som at dokke rumfart\u00f8jer, styre robotarme og ganske enkelt finde vej rundt i nye omgivelser.<\/p>\n

Virtual reality-brillerne vil blive sendt til Den Internationale Rumstation, s\u00e5 astronauterne der kan forts\u00e6tte eksperimentet. Man g\u00e5r ud fra, at jo mere erfaring man har med v\u00e6gtl\u00f8shed, jo bedre kan ens vestibul\u00e6re system klare det. Hvad tror du, resultaterne vil blive? Vil de erfarne astronauter v\u00e6re i stand til at finde den gyldne m\u00f8nt p\u00e5 rekordtid?<\/p>\n

Sjovt faktum:<\/b> Denne forskning kan m\u00e5ske hj\u00e6lpe mennesker p\u00e5 Jorden, der lider af sygdomme som f.eks. Alzheimers sygdom.<\/p>","protected":false},"excerpt":{"rendered":"
