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.
