101-nights -sleep and dream study night 093

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，对娜塔莉梦境的主观感知开展客观定量分析，以期在梦境感知与脑电信号两大维度间建立关联。睡眠期间，大脑活动与觉醒状态时相仿，但神经系统中系统发育层面较为古老的结构——丘脑（thalamus）会将个体与外界环境隔绝开来。不过这种隔绝并非完全彻底，部分外界刺激会被融入梦境叙事之中。为搭建脑电记录与娜塔莉梦境叙事之间的关联桥梁，本研究以听觉刺激作为潜在干扰机制开展实验。 “101夜”是一项纵向数据集。本研究的核心在于整合两类截然不同的知识领域，以记录并呈现梦境体验：在连续101个夜晚中，生理与行为数据会与梦者的内在心理活动持续配对，旨在构建二者间的对话关系。该数据集具备独特性，可应用于科学分析、方法学开发以及包括认知科学与多模态艺术在内的各类艺术创作项目。这项前所未有的研究项目可从内部与外部双视角呈现娜塔莉的梦境，涵盖连续101个昼夜的海量数据。 本项目产出四项直接成果： 1. 依托256个传感器的连续101夜记录，共生成952GB脑数据，涵盖娜塔莉的身体运动数据（动作测量（actimetry）与红外摄像采集）； 2. 计算机系统触发的语音音频日志，每晚均标注精确触发时间； 3. 娜塔莉每日撰写的梦境日记内容； 4. 逐日活动记录。
