The galvanic skin response can be recorded as a reduction of skin resistance (Fere, 1888) or as a change of skin potential (Tarchanoff, 1890). Accompanying this response there may occur a vasoconstriction of the digits, shown by reduction of volume, pulsation, and blood flow. In the past there has been discussion about the relationship between the electrical and the vascular events. Recently La...

Cervical spondylosis is a broad term which describes the age related chronic disc degeneration. The degenerative changes start in the intervertebral disc with osteophyte formation and lead to physiological degenerative cascade that contributes to biomechanical changes that result in neural and vascular compression. Autonomic nervous system (ANS) influences the functions of nearly all organ syst...

Abstract Despite the growing application of augmented reality in advertising, there is limited understanding about how customers respond to their interaction with advertising and it differs from a standard paper-based advertising. Augmented ads are immersive, interactive, lifelike, which means they may help companies create an emotional connection customers. The authors test if would terms affe...

Multiple personality disorder has been associated with marked psychophysiologic alterations ever since careful clinical observations have been made on this perplexing disorder. Physical symptoms known to be associated with multiple personality include headaches, conversion symptoms, changes in voice, seizure-like activity, unexplained pain or insensitivity to pain, alterations in handedness or ...

While it is known that anxiety or emotional arousal affects skin sympathetic nerve activity (SSNA), the galvanic skin response (GSR) is the most widely used parameter to infer increases in SSNA during stress or emotional studies. We recently showed that SSNA provides a more sensitive measure of emotional state than effector-organ responses. The aim of the present study was to assess whether the...

This paper presents a frequency modulation based readout circuit for the measurement of skin conductance or resistance. A charge pump based frequency-to-voltage converter circuit with adjustable sensitivity is used to convert the frequency shifts due to skin resistance changes into voltage variations. The readout circuit improves the measurement accuracy and artifact rejection in measurements o...

We investigated changes of postural responses to repeated bipolar galvanic vestibular stimulation on 5 consecutive days and once again after 3 months. Subjects consisted of 21 healthy volunteers. Except for the first day did the induced torque variance in response to galvanic vestibular stimulation not decrease within each test session, but there was a major reduction from day to day (p< 0.001)...
