Electrodermal Activity of Healthy Volunteers while Awake and at Rest

This dataset of electrodermal activity was collected from 11 healthy volunteer
subjects who were awake and at rest in seated position. The activity was
recorded from each subject's non-dominant hand for one hour at 256 Hz.
Electrodermal activity measures changing electrical conductance of the skin as
an indicator of sweat gland activity. Sweat glands are a primitive part of the
fight-or-flight response. These data were collected as part of a larger study
to understand and build computational models for autonomic nervous system
activity (including electrodermal activity) with approval from the
Massachusetts Institute of Technology Committee on the Use of Humans as
Experimental Subjects (COUHES). The second dataset of electrodermal activity
was collected from 11 healthy volunteer subjects who were under computer-
controlled propofol sedation. The activity was recorded from each subject's
left hand for about 3 hours at 500 Hz. These data were collected with approval
from the Massachusetts General Hospital Human Research Committee.

这个皮肤电活动（Electrodermal Activity）数据集采集自11名清醒且处于静息坐姿的健康志愿者受试者。研究人员从每位受试者的非优势手记录其皮肤电活动，时长1小时，采样频率为256 Hz。皮肤电活动通过测量皮肤电导的变化来反映汗腺活动，而汗腺是人体“战斗或逃跑”反应的原始组成部分。这些数据是一项更大规模研究的一部分，该研究旨在理解自主神经系统活动（包括皮肤电活动）并构建其计算模型，且已获得麻省理工学院人体实验受试者使用委员会（COUHES）的批准。

第二个皮肤电活动数据集同样采集自11名健康志愿者受试者，他们处于计算机控制的丙泊酚镇静状态。研究人员从每位受试者的左手记录其皮肤电活动，时长约3小时，采样频率为500 Hz。这些数据的采集已获得麻省总医院人类研究委员会的批准。
