“你爱不爱我”,这个在恋爱中最频繁出现的问题,未来或许可以通过科技手段来验证。近日,一项由中国科技大学、西南大学和美国西奈山伊坎医学院的科研人员共同完成的联合研究在2月国际期刊《人类神经科学前沿》上发表。研究结果表明,即使在静息状态下,爱情仍会对人类的大脑造成一定的影响。
  

  浪漫爱情会影响静息状态的大脑功能

科学家们过去的研究指出,当处在热恋中的个体看着自己恋人照片时,大脑中参与加工奖赏、动机和情绪调控的脑区会出现激活增强。“然而,浪漫爱情是否会影响静息状态(即没有任何具体的任务)的大脑功能,之前却并没有具体的研究。”领导这项研究的中国科学技术大学生命科学学院脑功能与脑疾病中科院重点实验室教授张效初25日告诉记者。
  

  2个不同区域会因爱情受到影响

大脑12个不同区域会因爱情受到影响

该项研究于2013年3月发起,历时1年11个月。研究对100位大学生进行静息状态下的脑部扫描,其中约1/3的参与者正处于热恋,1/3刚结束一段感情,剩下1/3的人单身且从没谈过恋爱。

初步研究结果显示,大脑有12个不同区域会因爱情情感而受到不同的影响,“这说明不管恋人是否在眼前,爱情的存在已经在日常情况下持续性地影响着大脑。”张效初说。
  

  一旦失恋 大脑尾状核区活跃度会降低

一旦失恋 大脑尾状核区活跃度会降低

相比于分手组和单身组,恋爱组被试的功能连接显着增强,主要体现在涉及奖赏、动机和情绪调控系统(包括背侧扣带前回、脑岛、尾状核、杏仁核、和伏隔核等)和社会认知系统(包括颞顶联合区、后扣带回、内侧前额叶、颞叶下回、楔前叶和颞叶等)内的功能连接。 张效初表示,在以上两个系统的部分脑区,其功能连接强度与恋爱组的恋爱时间成正比,与分手组的分手时间显着呈反比。

值得一提的是,大脑的尾状核区域,也许是对爱情反应最敏感的区域之一。研究显示,一旦失恋,尾状核的活跃强度会显着降低,甚至比从未恋爱的人更低,然后随着时间慢慢恢复。

研究将有助于解决毒品、性成瘾问题

张效初目前正从事“成瘾中渴求产生与调控机制”方向研究。“我们收集不同人群(包括正常人和成瘾患者)各个方面数据,对正常渴求(食物/性)和异常渴求(成瘾)进行比较,未来希望可以通过磁共振等工具告诉我们大脑哪个区域的信号在异常渴求中变得比较强或比较弱,为解决毒品、网络或者性成瘾等问题提供指导和帮助。”
