Pulse Amplitudes from electrodermal activity collected from healthy volunteer subjects at rest and under controlled sedation

This dataset of electrodermal activity was collected from 11 healthy volunteer
subjects who were awake and at rest in seated position and 11 different
healthy volunteers who were under controlled propofol sedation. For the awake
and at rest subjects, the activity was recorded from each subject's non-
dominant hand for one hour at 256 Hz. For the controlled propofol sedation
subjects, the activity was recorded from each subject's left hand for about
3-4 hours at 500 Hz. From the raw data, EDA pulses were extracted and the
pulse times and amplitudes reported. 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) and the
Massachusetts General Hospital Human Research Committee.
