人类大脑要到30岁后才成熟?你的大脑“成年”了吗

环球时报 2019-05-07 00:09:43

  研究表明,人的大脑在18岁时仍在发生重大变化,其中不少变化会影响他们的行为,使他们更容易患上心理疾病。

  他补充说道,大部分国家都规定18岁了就算成年,一旦年满18就可以投票、买酒、抵押贷款等等,但这样的规定其实只是让教育、医疗和法律系统运转起来更为简便。

  “What we’re really saying is that to have a definition of when you move from childhood to adulthood looks increasingly absurd,” professor Peter Jones explained at the meeting。 “It’s a much more nuanced transition that takes place over three decades。“

  “我们真正想要表达的是,给从童年转变为成年定义一个时间点,看起来越来越荒谬了,”琼斯教授在会议上解释说,“这是一个非常微妙的过渡过程,大概会持续三十多年。”

  “There isn‘t a childhood and then an adulthood。 People are on a pathway, they’re on a trajectory。”

  他说:“并不是说童年之后立即就是成年。人们始终都走在(逐渐成熟)这条路上,沿着这条轨道慢慢前进。”

  医学博士弗朗西丝·延森(Frances E.Jensen)在《男士健康》三月刊中也发表文章,指出我们的大脑要到30岁才能完全发育起来。

  The prolonged state of development allows us to learn new concepts more quickly, she said。 Plus, people get deeper sleep in their 30s, meaning the impact of those late night Netflix binges are partially counterbalanced, Men‘s Health sleep advisor Dr。 Christopher Winter, said。 But this also means that excessive alcohol or drug use while your brain is still developing may have lasting impact。

  她说,大脑长期处于发育状态会让我们能快速学习新概念。此外,男性健康睡眠顾问克里斯托弗·温特博士说,人们在30多岁时睡得更深,这在一定程度上能抵消熬夜在网飞上刷剧的影响。但也同时意味着,过度饮酒或吸 毒,会对你仍在发育的大脑产生持久的影响。
