The aim of this study was to investigate the effect of dream recall on the neurophysiological correlates of emotional processing. The hypothesis was that dream recall will produce an increased activation of fronto-limbic areas during an emotional task. Thirty-seven women were recruited and randomly assigned to two groups. Both groups were exposed to a visual task with emotional images (positive vs. negative) presented in two stages (T0 and T1). Between T0 and T1, in the experimental group, women were asked to recall and report a dream; whereas, in the control group, they were asked to report their work experiences. Electroencephalography data were continuously recorded in each participant, except during the personal report session. Event-related potential analyses showed an interaction effect of Time (T0 vs. T1) × Condition (positive vs. negative) × Group (experimental vs. control) in temporo-parietal montage at P100; and Condition × Hemisphere × Group in frontal montage from 200 to 1,000 ms. Standardized low resolution electromagnetic tomography results showed an increased activation of the fronto-limbic areas and a decreased activation of the anterior middle frontal gyrus and temporo-parietal junction at T1 compared with T0 in the experimental group. Conversely, in the control group, a decreased activation in limbic areas was found. Dream recall was associated with an increased intensity of the limbic and temporal circuits during emotional exposition, suggesting that dream recall seems to favor an emotional response.

梦境回忆对情绪处理影响的神经相关性。

本研究的目的是调查梦境回忆对情绪处理的神经生理学相关性的影响。假设是，在情绪任务期间，梦境回忆会增加额叶边缘区域的激活。招募了 37 名女性并随机分配到两组。两组都接受视觉任务，其中情感图像（正面与负面）呈现在两个阶段（T0 和 T1）。在 T0 和 T1 之间，在实验组中，女性被要求回忆并报告一个梦；而在对照组中，他们被要求报告他们的工作经历。除个人报告期间外，每个参与者的脑电图数据都被连续记录。事件相关电位分析显示时间（T0 vs. T1）×条件（阳性 vs. T1）的交互作用。阴性）×组（实验组与对照组）在 P100 的颞顶叶蒙太奇；和条件 × 半球 × 组在正面蒙太奇从 200 到 1,000 毫秒。标准化的低分辨率电磁断层扫描结果显示，与实验组的 T0 相比，T1 时额边缘区的激活增加，额中前回和颞顶交界处的激活减少。相反，在对照组中，发现边缘区域的激活减少。梦境回忆与情绪表达过程中边缘系统和时间回路的强度增加有关，这表明梦境回忆似乎有利于情绪反应。标准化的低分辨率电磁断层扫描结果显示，与实验组的 T0 相比，T1 时额边缘区的激活增加，额中前回和颞顶交界处的激活减少。相反，在对照组中，发现边缘区域的激活减少。梦境回忆与情绪表达过程中边缘系统和时间回路的强度增加有关，这表明梦境回忆似乎有利于情绪反应。标准化的低分辨率电磁断层扫描结果显示，与实验组的 T0 相比，T1 时额边缘区的激活增加，额中前回和颞顶交界处的激活减少。相反，在对照组中，发现边缘区域的激活减少。梦境回忆与情绪表达过程中边缘系统和时间回路的强度增加有关，这表明梦境回忆似乎有利于情绪反应。发现边缘区域的激活减少。梦境回忆与情绪表达过程中边缘系统和时间回路的强度增加有关，这表明梦境回忆似乎有利于情绪反应。发现边缘区域的激活减少。梦境回忆与情绪表达过程中边缘系统和时间回路的强度增加有关，这表明梦境回忆似乎有利于情绪反应。
