nature:美发现恐惧症能通过基因遗传

2013-12-05 陈龙 环球网

人们通常认为我们早期的经历和儿时的记忆是恐惧症的主要根源,其实不然。据英国《镜报》12月2日报道,美国埃默里大学的科学家们在近期的实验中发现:恐惧和恐惧症是可以通过基因遗传的。 在实验中,他们训练小鼠,使它们对樱桃花香产生恐惧,然后再对其后代进行实验,结果发现小老鼠虽然生存环境没有受到干扰,却有更强烈的恐惧感。为此,科学家们又进一步通过试管培育小鼠实验,验证了恐惧和恐惧症是可以遗传的。布

人们通常认为我们早期的经历和儿时的记忆是恐惧症的主要根源,其实不然。据英国《镜报》12月2日报道,美国埃默里大学的科学家们在近期的实验中发现:恐惧和恐惧症是可以通过基因遗传的。

在实验中,他们训练小鼠,使它们对樱桃花香产生恐惧,然后再对其后代进行实验,结果发现小老鼠虽然生存环境没有受到干扰,却有更强烈的恐惧感。为此,科学家们又进一步通过试管培育小鼠实验,验证了恐惧和恐惧症是可以遗传的。布赖恩·迪亚斯和克里·雷斯勒博士也在《自然神经科学》周刊发表研究成果阐明,一般后代和试管小鼠,这两种交叉和隔代的恐惧现象均属于生物遗传的表现特征。

这项研究成果能都帮助人们更好地认识和理解心理健康问题,如创伤后应激障碍等,同时也为人们解决这些问题提供了更好的平台,也预示该研究具有广阔而深远的前景。

Autism Res :自闭症的严重性根源于恐惧

       大多数人都能控制好自己的情绪,适时进行调整。        然而,新研究表明,患有自闭症的儿童很难摆脱恐惧的纠缠。更值得注意的是,杨百翰大学的研究发现,这种长久性的恐惧与典型的自闭症症状紧密相关,如:不停重复的行为和拒绝接受改变。        &nb
