101-nights -sleep and dream study night 053

The research project presented aims at putting the personal perception of Nathalie’s dreams through an objective, quantitative analysis using electroencephalography (EEG), in an attempt to establish a linkage between the two dimensions. During sleep periods, brain activity is similar to that of an awakened state, yet the thalamus, a phylogenetically ancient structure in the nervous system, isolates us from the environment. But this isolation is not total, and sometimes external stimuli are incorporated into the plot of our dreams. To establish a bridge between the record (EEG) and Nathalie’s dream narrative, we experiment with auditory stimuli as a possible mechanism of interference. The 101 nights is a longitudinal dataset. At the core of the study is the concordance of two divergent fields of knowledge to record and represent the dream experience. For 101 nights physiological and behavioral data are continuously paired with the dreamer’s inner life, geared towards a dialogue. A unique dataset for scientific analyses, methodological developments as well artistic projects, including cognitive science and multiple modalities of art. The unprecedented project allows an internal and external perspective on Nathalie’s dreams, containing extensive data for 101 consecutive nights and days. the project produced four immediate results: 1. 952 GB of brain data was produced by the registry of 256 sensors over the period of 101 nights in continuity, including her body movement (actimetry and infrared camera).<br> 2. the audio logs of the words triggered by the computer system, each night with their exact time.<br> 3. Nathalie’s daily dream diary entries.<br> 4. day-by-day activity.本研究项目旨在通过脑电图（electroencephalography，EEG）技术对娜塔莉的梦境感知开展客观量化分析，以期在梦境体验与脑活动两个维度间建立关联。睡眠期间，大脑活动状态与觉醒时相似，但神经系统中系统发育古老的丘脑结构会将个体与外界环境隔绝。然而这种隔绝并非完全彻底，有时外界刺激会融入梦境叙事当中。为搭建脑电图记录与娜塔莉的梦境叙事之间的桥梁，本研究尝试以听觉刺激作为潜在干扰机制开展实验。 本次研究的101夜数据集属于纵向数据集。本研究的核心在于融合两类迥异的知识领域，以记录并呈现梦境体验：在连续101个夜晚中，生理与行为数据将持续与梦者的内在心理活动进行配对，旨在构建双向对话机制。该数据集兼具科学分析、方法论开发与艺术创作的多元价值，可应用于认知科学及多模态艺术等多个领域。这项前所未有的研究，能够从内部与外部视角展现娜塔莉的梦境，包含连续101个昼夜的海量数据。 本项目取得了四项直接成果： 1. 依托256个传感器的连续101夜记录，生成了总计952GB的脑活动数据，同时涵盖受试者的身体运动数据（采用运动测量法与红外摄像技术采集）； 2. 计算机系统每日触发的语音日志，每条均标注精确的触发时间； 3. 娜塔莉每日撰写的梦境日记； 4. 逐日记录的日常活动数据。
