Abstract
Electrodermal activity is the term used to describe changes in the electrical activity of the skin. It is usually measured by passing a small current via electrodes positioned on a palmar skin surface (e.g., fingertips). The electrical fluctuations represent changes in the functioning of the underlying sweat glands usually as a result of sympathetic cholinergic activity. Accordingly, electrodermal measures have been associated with physiological changes that accompany psychological processes underlying attention, emotion, stress, etc. and are frequently used within mental stress testing paradigms.

Responsibility specificity, particularly facial expressiveness, supported the view that specific affects have unique patterns of reactivity, and consistency of the dimensional relationships between evaluative judgments and physiological response emphasizes that emotion is fundamentally organized by these motivational parameters.

Electrodermal activity (EDA) is now the preferred term for changes in electrical conductance of the skin, including phasic changes that have been referred to as galvanic skin responses (GSR), that result from sympathetic neuronal activity.

Sympathetic skin response has been proposed as a non-invasive approach to investigate the function of the sympathetic system and current procedures are not sufficiently reliable for diagnostic purposes, and show imperfect correlations both with clinical features and other measurements of autonomic, in particular, sudomotor dysfunction.

The findings point to a dissociation between neural systems controlling basal sympathetic tone (SCL) and transient skin conductance responses (SCRs), indicating that activity within VMPFC and OFC reflects a dynamic between exteroceptive and interoceptive deployment of attention.

Skin conductance level can serve as a stable and useful index of autonomic arousal in clinical trials, even in patients using beta-blocking medications, and nadolol had no significant effect on skin conductance.

Significant stability over a 1-year period was found for both patients and normal subjects for most EDA variables and for responder/nonresponder status, with test-retest correlations generally being higher for normal subjects.

A low‐cost system for monitoring human skin conductance responses (SCRs) in a clinical magnetic resonance (MR) scanner during functional imaging and the average scanner‐induced conductance noise level was suppressed sufficiently to allow SCR measurements over the full range of SCR amplitudes.
