Neuroscience Letters:健忘的遗传“贡献”

2014-03-24 佚名 生物360

家门钥匙又找不着了?那个人叫什么名字来着?哎呀,那个路牌没看见!生活中,常常可见到这样一些粗心大意、丢三落四的人。不过,这或许不能全怪他们,最新研究显示,基因在其中扮演了重要角色。 德国波恩大学的研究人员发现,大脑额叶中负责信号传输的一种名为 DRD2 的基因与健忘、注意力不集中有紧密联系。 研究人员随机选取了 500 名受访者,让他们评价自己平时是否注意力集中、是否健忘,并通过他们的唾液样本

家门钥匙又找不着了?那个人叫什么名字来着?哎呀,那个路牌没看见!生活中,常常可见到这样一些粗心大意、丢三落四的人。不过,这或许不能全怪他们,最新研究显示,基因在其中扮演了重要角色。

德国波恩大学的研究人员发现,大脑额叶中负责信号传输的一种名为 DRD2 的基因与健忘、注意力不集中有紧密联系。

研究人员随机选取了 500 名受访者,让他们评价自己平时是否注意力集中、是否健忘,并通过他们的唾液样本进行基因检测。结果发现, DRD2 基因有两个变体,拥有该基因一个变体的志愿者更容易出现注意力分散,记忆力较差的情况,且这种健忘常具有家族遗传性。

研究人员表示,即便注意力不集中、记忆力较差与遗传有关,也不代表人们对此没有任何办法。例如,这些丢三落四的人可以将要做的事情写在便签纸上,或尽量把家门钥匙放在同一个地方。
