The study suggests these deficits in sleep-related emotional processing may exacerbate（加剧，恶化） emotional problems experienced in the daytime by children with ADHD. For the study, healthy adults, healthy children and children with ADHD were shown pictures that had emotional relevance, such as a scary animal, or neutral pictures showing an umbrella or lamp. Participants were shown pictures in the evening, their brain activity was monitored as they slept, and recollections were tested the following morning. The researchers found that during sleep, regions of the brain thought to support consolidation of emotional memories were most active in healthy children, less so in healthy adults and least active in children with ADHD.   The study states, "While several studies reported a benefit from sleep with respect to emotional memory in healthy individuals, our results showed for the first time that healthy children outperform healthy adults." However, the authors add that this may be, in part, attributable to the child-oriented pictures used as stimuli.   Their results support the idea that frontal brain activity is critically to the consolidation of emotional memory in sleep, and this brain region is also implicated in the emotional symptoms seen in children suffering from ADHD. The authors add that further studies are needed to confirm whether this function of sleep in forming emotional memories develops with time in adults with ADHD, or whether the dysfunction persists in ADHD sufferers of all ages. 睡眠巩固（巩固，联合）的健康儿童的情感记忆，但不是在注意缺陷多动障碍（ADHD）的儿童，根据研究发表在5月29日，在开放获取期刊PLoS ONE Prehn由亚历山大·克里斯滕森和同事从石勒苏益格大学医院-荷尔斯泰因州。研究表明，睡眠相关的情感处理这些赤字可能加剧（加剧，恶化）情感与多动症儿童在白天遇到的问题。在这项研究中，健康的成年人，健康的儿童和儿童多动症，情绪相关的图片，如一个可怕的动物，或中性图片显示雨伞或灯的。与会者展示了在晚上的照片，监测他们的大脑活动，因为他们睡的，和回忆都呈第二天早上。研究人员发现，在睡眠过程中，想支持巩固情绪记忆的大脑区域最为活跃健康儿童，所以在健康成人和儿童多动症最不活跃的。   研究指出，“虽然一些研究的好处从睡眠与健康人的情感记忆，我们的研究结果表明，健康的孩子比健康成人的第一次。” 然而，作者补充说，这可能是，部分归功于面向儿童的图片作为刺激。   他们的研究结果支持这一想法，额叶脑活动是极为巩固情绪记忆在睡眠中，这个大脑区域也牵连在情感见于儿童患多动症的症状。作者补充说，还需要进一步研究，以确认这是否形成情感记忆的睡眠功能随着时间的发展，在成人多动症，或功能障碍是否依然存在注意力缺陷多动症患者的青睐。 “成千上万人疯狂下载。。。。。。 更多价值连城的绝密英语学习资料， 洛基内部秘密英语，技巧，策略 请在 网上 申请报名” 洛基国际英语 竭诚为您服务
