101-nights -sleep and dream study night 026

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，以期在脑电图记录与梦境感知两个维度间建立关联。睡眠期间，大脑活动与觉醒状态相似，但神经系统中系统发育古老的丘脑（thalamus）结构会将我们与外界环境隔绝开来。但这种隔绝并非完全彻底，有时外界刺激会融入我们的梦境叙事之中。为在脑电图记录与娜塔莉的梦境叙事之间搭建桥梁，本研究将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，以记录并呈现梦境体验。在连续101个夜晚的周期内，生理与行为数据会与梦者的内在体验持续配对，旨在构建双向对话机制。该数据集具备独特应用价值，可支撑科学分析、方法学开发以及涵盖认知科学与多模态艺术在内的各类艺术项目。这项前所未有的项目可从内部与外部双视角展现娜塔莉的梦境，涵盖了连续101个昼夜的海量数据。本项目产出了四项直接成果： 1. 借助256个传感器的连续101夜记录，共生成952 GB的大脑数据，其中包含受试者的身体运动数据（动仪测量（actimetry）与红外摄像）。 2. 计算机系统触发的语音日志，每晚均标注有精确的触发时间。 3. 娜塔莉每日撰写的梦境日记条目。 4. 逐日活动记录。
