Manyetik alan kullan\u0131larak beyin faaliyetlerinin de\u011fi\u015ftirilmesi, sigaray\u0131 b\u0131rakmada etkili, yeni bir y\u00f6ntem olabilir.<\/span><\/p>\n

Uzmanlar yapt\u0131klar\u0131 deneylerde beynin manyetik alan kullan\u0131m\u0131yla uyar\u0131lmas\u0131 tekni\u011fiyle, beyindeki nikotin ba\u011f\u0131ml\u0131l\u0131\u011f\u0131n\u0131 “ortadan kald\u0131rmay\u0131” denediklerini aktar\u0131yorlar.<\/p>\n

N\u00f6robilim 2013 konferans\u0131na sunulan bulgular, bu tekni\u011fin ba\u011f\u0131ml\u0131l\u0131\u011f\u0131 ger\u00e7ekten azaltabilece\u011fini ya da sona erdirebilece\u011fini g\u00f6steriyor.<\/span><\/p>\n

Ancak uzmanlar ba\u011f\u0131ml\u0131l\u0131k tedavisinde uygulamaya konmadan \u00f6nce daha kapsaml\u0131 deneyler yap\u0131lmas\u0131 gerekti\u011fini s\u00f6yl\u00fcyorlar.<\/span><\/p>\n

\u0130srail’deki Ben Gurion \u00dcniversitesi’nden bir uzman ekip, yapt\u0131klar\u0131 deneylerde, manyetik alan\u0131, beynin nikotin ba\u011f\u0131ml\u0131l\u0131\u011f\u0131yla ilgili oldu\u011fu d\u00fc\u015f\u00fcn\u00fclen iki b\u00f6lgesi olan prefrontal korteks ve insula kortekse uygulad\u0131lar.<\/span><\/p>\n

Bu grubun \u00fc\u00e7te biri alt\u0131 ay sonra sigaray\u0131 tamamen b\u0131rakt\u0131.<\/span><\/p>\n
