101-nights -sleep and dream study night 079

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.本研究项目旨在借助脑电图（electroencephalography，EEG）技术，对娜塔莉的梦境主观感知开展客观量化分析，以期建立二者间的关联。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上极为古老的结构——丘脑——会将个体与外界环境隔绝。不过这种隔绝并非完全彻底，有时外界刺激会被融入梦境的叙事脉络之中。 为搭建脑电记录与娜塔莉的梦境叙事之间的桥梁，本研究以听觉刺激作为潜在的干扰机制开展实验。“101夜”为一项纵向数据集。本研究的核心在于整合两个截然不同的知识领域，以记录并展现梦境体验。在连续101个夜晚中，生理与行为数据会与梦者的内在梦境体验持续匹配，旨在构建二者间的对话关联。 该数据集具备独特研究价值，可应用于科学分析、方法学开发以及各类艺术创作，涵盖认知科学与多模态艺术等领域。这项前所未有的研究项目可从内部与外部双重视角解析娜塔莉的梦境，包含连续101个昼夜的海量观测数据。 本项目取得了四项直接成果： 1. 借助256个传感器的连续记录，在101个夜晚的周期内获取了总计952GB的脑电数据，同时包含受试者的身体运动数据（动作测量与红外摄像采集）； 2. 计算机系统触发的语音音频日志，每条日志均标注了精确的触发时刻； 3. 娜塔莉每日撰写的梦境日记条目； 4. 每日日常活动记录。
