In this study, GSR was recorded from fibromyalgia patients (FM) and healthy controls (HC) while they underwent scanning with -fallypride (FAL) Positron Emission Tomography (PET). GSR could potentially give insight to novel aspects of DA function. Galvanic skin response (GSR), is a physiological measure of nervous system activation. It is not known how central dopamine function in pain is associated with objective peripheral measurements that are thought to be associated with the presence of pain and stress. Functional alterations of neurotransmitters such as dopamine (DA) have been implicated in fibromyalgia neuropathology. With neuroscientific methods, reactions to movies can be measured and quantified, e.g. GSR detecting stress and excitement.Fibromyalgia is a chronic pain disorder that presents itself with no apparent medical explanation for the pain. Nevertheless, arousal and intuitive liking are factors that all types of movies, especially movie trailers, are supposed to provide. Horror movies are one example of how movies can create a large range of bodily and psychological reactions. Especially, once the tension is released as the feeling of release boosts our positive feelings. As long as our brain knows that we are only watching a movie and are in a safe spot, this cocktail can make us feel great. The feeling of fear can trigger our fight or flight response which results in a boost of endorphins, adrenaline and dopamine. It is increased slowly and the physical and emotional arousal rises while watching horror movies. Tension in combination with relevance and unrealism is a primary success factor of the highly controversial genre. Horror movies, more than any other genre, uses sound to create tension. These insights are used amongst others to test and improve communications, marketing messages, advertisements, and product/service experiences to achieve the desired emotional reaction.ĭid you know that about 10% of the population enjoys arousal caused by horror movies? bored, relaxed, engaged) during that experience.

Then, the voltage difference across the electrodes is used to calculate the skin conductivity which allows conclusions on their emotional state (e.g. For this purpose, two electrodes are attached to the hands of study participants while they are interacting with an object or a person. We use GSR to measure changes of transpiration with high sensitivity. Conversely, during boredom or relaxation transpiration decreases. The intensity of our emotional arousal (but not the type of emotion) can be derived from transpiration.

This is also the case when experiencing emotions such as anger or frustration. When we experience arousal such as stress or joy, we begin to sweat as our sympathetic nervous system increases its activity. The GSR method is based on the correlation between our mental and physiological reactions – transpiration for example.
