101-nights -sleep and dream study night 004

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).
2. the logs of the words triggered by the computer system, each night with their exact time.
3. Nathalie’s daily dream diary entries.
4. day-by-day activity.

睡眠状态下，大脑活动与觉醒状态相仿，但神经系统中系统发育古老的丘脑（thalamus）结构会将个体与外界环境隔绝开来。不过此种隔绝并非绝对，部分外界刺激有时会融入梦境的叙事脉络之中。为搭建脑电图（EEG）记录与娜塔莉的梦境叙事之间的关联桥梁，我们以听觉刺激作为潜在的干扰机制开展了相关实验。

《101夜》是一项纵向数据集。本研究的核心在于整合两类迥异的知识领域，以记录并呈现梦境体验。在整整101个夜晚中，生理与行为数据持续与梦者的内在精神世界进行配对关联，以期实现二者的对话互通。

本数据集是可用于科学分析、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创作项目的独特资源。这项前所未有的研究项目兼具对内与对外双重视角，可全面呈现娜塔莉的梦境，涵盖连续101个昼夜的海量数据。

该项目产出了四项直接成果：
1. 连续101个夜晚中，通过256个传感器的持续记录，共采集得到952GB的脑数据，同时包含受试者的身体运动数据（活动量测定法（actimetry）与红外摄像采集）；
2. 计算机系统生成的词汇触发日志，每晚的日志均标注精确的触发时间；
3. 娜塔莉每日撰写的梦境日记条目；
4. 逐日活动记录。
