A week of a student's electrodermal activity

Joi Ito:

Obviously, this is just one student and doesn't necessarily generalize, but I love that the electrodermal activity is nearly flatlined during classes. ;-) (Note that the activity is higher during sleep than during class...)

"Changes in skin conductance at the surface, referred to as electrodermal activity (EDA), reflect activity within the sympathetic axis of the Autonomic Nervous System (ANS) and provide a sensitive and convenient measure of assessing alterations in sympathetic arousal associated with emotion, cognition, and attention."
