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，对娜塔莉的梦境个人感知开展客观量化分析，以期建立梦境感知与脑电信号间的关联。睡眠时的大脑活动状态与觉醒状态相似，但丘脑——神经系统中系统发育起源古老的结构——会将个体与外界环境隔绝。不过该隔绝并非完全彻底，部分外界刺激有时会被纳入梦境情节之中。为搭建脑电图记录与娜塔莉梦境叙事间的桥梁，本研究将听觉刺激作为潜在干扰机制开展实验。“101夜”为纵向研究数据集，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个夜晚中，生理与行为数据会与梦者的内在体验持续配对，旨在实现二者的交互对话。本数据集兼具独特性，可用于科学分析、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项目研究。这项史无前例的研究项目为娜塔莉的梦境提供了内、外双重视角，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通道传感器的连续101夜记录，共产生952GB脑数据，同时涵盖受试者的身体运动数据（动度测量与红外摄像）； 2. 计算机系统触发的语音音频日志，每条日志均标注每晚的精确触发时间； 3. 娜塔莉每日的梦境日记记录； 4. 每日活动日志。
