TIME’\u0131n haberine g\u00f6re, Florida \u00dcniversitesi Uygulamal\u0131 Fizyoloji ve Kinezyoloji Profes\u00f6r\u00fc Rachel Seidler ve 10 bilim insan\u0131n\u0131n yapt\u0131\u011f\u0131 ara\u015ft\u0131rmada, beyinde omurilik s\u0131v\u0131s\u0131yla dolu kar\u0131nc\u0131k k\u0131s\u0131mlar\u0131n\u0131n, uzayda \u00e7ok zaman ge\u00e7iren astronotlarda geni\u015fleyebildi\u011fi g\u00f6r\u00fcld\u00fc.<\/p>\n
Uzmanlar, astronotlar\u0131n beyinlerinde meydana gelen \u015fi\u015fkinli\u011fin, D\u00fcnya’ya d\u00f6n\u00fc\u015flerinin ard\u0131ndan ge\u00e7ti\u011fini ancak tamamen iyile\u015fme i\u00e7in bir sonraki uzay yolculu\u011fu \u00f6ncesinde, astronotlar\u0131n uzun s\u00fcre yery\u00fcz\u00fcnde kalmalar\u0131 gerekti\u011fini kaydetti.<\/p>\n
Profes\u00f6r Seidler, uzayda ge\u00e7irilen zamana paralel olarak kar\u0131nc\u0131klardaki \u015fi\u015fkinli\u011fin devam etti\u011fini; \u00f6zellikle 6 ay\u0131 a\u015fan uzay yolculuklar\u0131 sonras\u0131nda bunlar\u0131n eski haline gelmesinin ortalama 3 y\u0131l s\u00fcrd\u00fc\u011f\u00fcn\u00fc s\u00f6yledi.<\/p>\n
Ara\u015ft\u0131rmaya konu 30 astronottan 8’i son iki hafta i\u00e7erisinde k\u0131sa s\u00fcreli\u011fine, 18’i alt\u0131 ayl\u0131\u011f\u0131na uzayda g\u00f6revliydi. 4 astronot ise 1 senedir uzay g\u00f6revinde bulunuyordu.<\/p>\n
Astronotlar\u0131n beyinlerini inceleyen ara\u015ft\u0131rmac\u0131lar, uzayda iki hafta kalanlar\u0131n bu organlar\u0131n\u0131n geni\u015flemedi\u011fini g\u00f6zlemlerken alt\u0131 ay ve bir y\u0131ll\u0131k g\u00f6reve gitmi\u015f olanlar\u0131n beyinlerinde ise y\u00fczde 11 ile 25 aral\u0131\u011f\u0131nda geni\u015fleme tespit etti.<\/p>\n
Sonu\u00e7lar, uzay yolculu\u011funda beyindeki kar\u0131nc\u0131k geni\u015flemesinin \u00e7o\u011funlukla alt\u0131 ayda ya\u015fand\u0131\u011f\u0131na i\u015faret ediyor.<\/p>\n
Yap\u0131lan testlerde, astronotlar\u0131n D\u00fcnya’ya geri d\u00f6n\u00fc\u015f\u00fcn\u00fcn 7’nci ay\u0131nda, kar\u0131nc\u0131klarda y\u00fczde 55 ila 64 k\u00fc\u00e7\u00fclme g\u00f6zlemlendi. S\u00f6z konusu b\u00f6lgelerin tamamen d\u00fczelmesi ise daha \u00e7ok vakit al\u0131yor.<\/p>\n
