New York’daki ekibin \u00e7al\u0131\u015fmas\u0131 bunun \u015fu ana kadar saptanabilen en a\u00e7\u0131k \u00f6rne\u011fini olu\u015fturuyor.<\/p>\n

Travma an\u0131s\u0131 da \u00e7ocuklara ge\u00e7ebilir mi?<\/b><\/p>\n

Bu farelerden do\u011fan yavrular ise, daha \u00f6nce hi\u00e7 bir zaman kiraz \u00e7i\u00e7e\u011fi koklamad\u0131klar\u0131 halde bir s\u00fcre sonra bu kokuyu ald\u0131klar\u0131nda korkuyla tepki verdiler.<\/p>\n

Bu \u015fekilde e\u011fitilmemi\u015f farelerden do\u011fan yavrularda ise bu tepki g\u00f6r\u00fclmedi.<\/p>\n

Bu durumda bu e\u011fitimi alm\u0131\u015f farelerin spermindeki genlere bu \u00e7evre etkisinin eklemlendi\u011fi ve yavrular\u0131n daha duyarl\u0131 olmas\u0131n\u0131 sa\u011flad\u0131\u011f\u0131 anla\u015f\u0131l\u0131yor.<\/p>\n
