Scientists have shown that there is a degree of truth in the old adage that love is blind.They have found that feelings of love lead to a suppression of activity in the areas of the brain controlling critical thought.It seems that once we get close to a person,the brain decides the need to assess their character and personality is reduced.The study,by University College London,is published in NeuroImage.
The researchers found that both romantic love and maternal love produce the same effect on the brain.They suppress neural activity associated with critical social assessment of other people and negative emotions.The UCL team scanned the brains of 20 young mothers while they viewed pictures of their own children,children they were acquainted with,and adult friends.The team found that the patterns of brain activity were very similar to those identified in an earlier study looking at the effects of romantic love.Both studies recorded increased activity in parts of the brain's "reward system".When these areas are stimulated--as they can be by food and drink,or even monetary gain--they produce feelings of euphoria.But perhaps more surprisingly,both studies also showed reduced levels of activity in the systems necessary for making negative judgements.
Lead researcher Dr Andreas Bartels said it was crucial that both romantic and maternal love were viewed by the brain in a highly positive way--because both were crucial to the perpetuation of the species.
科学家已经证明,“爱情使人盲目”这句古老的谚语在一定程度上是一句真理.他们发现坠入爱河的感觉会抑制大脑中控制批判性思维的区域的活跃程度.似乎我们一旦接近有好感的那个人,大脑就自作主张地降低评估他/她的人格和个性的需要.
【神经影像】期刊近日发表了伦敦大学学院的研究.研究者发现,爱情和亲情都能对大脑产生同样的影响.这两者都会减弱部分神经的活跃程度,包括对他人进行批判性社会评价和产生负面情绪的神经.伦敦大学学院研究组对二十位年轻母亲进行实验,向她们展示她们亲生孩子的照片,她们熟识的孩子的照片和她们的成年朋友的照片,并同时扫描她们的大脑.研究人员发现,与先前实验中发现的爱情对大脑的影响比较,实验中她们大脑的活动模式受到的影响十分相似.这两项研究都记录了大脑中属于“奖赏系统”的区域活跃度增加.如同食物,饮料甚至金钱收入对这一区域产生的刺激一样,实验中照片对大脑的刺激使人产生幸福愉快感.不过更令人吃惊的是,这两项研究也都表明负责作出负面判断的大脑区域活跃度有所降低.
研究负责人安德里亚斯·巴特尔斯博士表示,研究结果的关键是,大脑用一种高度积极正面的方式看待爱情和亲情,而这对人类物种的延续是至关重要的.
