patient was unable to hold a job (tardiness and disorganization), made poor decisions regarding finances and relationships. fails to show skin conductance to emotional stimuli bloody guy on the ground (not pleasant, very arousing) cute seal (very pleasant, not very arousing) Skin conductance response to emotional pictures add eyedrops of belladona to eyes to give women wider pupils (make them more 'attractive') nightshade (produces atropa belladonna (molecule) that releases atropine which acts as an antagonist to the muscarinic cholinergic receptors and causes pupil dilation) on/off switch (only sympathetic innervation) not as complicated post-gangliolic neurotransmitter of sweat glands is Acetylcholine (as opposed to norepinephrine). facilitate manipulative contact (friction) get rid of excess heat (get rid of excess heat) b/c water is a better conductor of heat (thermoregulation) nonspecific conductance responses = bursts of skin conductance activityДЇunction of sweat glands: provide friction to hold onto objects skin conductance response on top of this level = phasic level (0.05-5 microsiemens) The first step of this evolutionary process compared the survey method with the GSR method in an attempt to determine if GSR data are similar to survey stress data in terms of statistics and trends. measure of skin conductance in microSiemans at tonic level (2-50 microsiemens) This report discusses the use of a third method to measure Soldier stress: galvanic skin response (GSR). as more sweat develops from sympathetic NS activation, conductance increases measure in terms of resistance or conductance (inverse) EDA (any activity that is measured on the skin in relation to sweat glands) or GSR Darwin was one of the first to study the emotional responses within cross-cultures and cross-species to understand the neural basis of emotion emotional arousal signals physiological responses

buildup of sympathetic arousal before firing of starting gun at race Electrodermal System (measure sweat on the skin) We use neuroendocrine (cortisol), autonomic nervous system (heart rate variability, skin conductance, pupil diameter), somatic muscles (EMG), and eye-tracking methodology to examine how stress affects cognition. We are interested in how psychological stress affects attention, learning, memory, social cognition and decision making.

The aim of the present work is to utilize the galvanic skin response of students both at high school and at the university using various stimuli related to the education processes, do signal processing to the resulted time series and device indicators that will describe the objective response of the students.The Cognitive Neuroscience of Stress Lab is located in the Department of Psychology at Saint Louis University

In education most of the research is done using subjective tools and many times not concurrently, to assess the various pertinent aspects, like interest, attention, etc. At the same time the computer can be utilized to deliver the stimuli to the subjects thus allowing flexibility, uniformity, a variety of stimuli and combinations of them. With the advent of electronics it is possible to continuously measure the galvanic skin response, store it in a computer and apply signal processing to extract valuable information. It is a relatively simple and not invasive method and can be applied with little disturbance to subjects. Skin has the ability to conduct electricity. Even though this is the case, it is impossible to detect the type of emotion or physical change that elicited the reaction by simply looking at the graph. Galvanic skin response has a long history and is regularly employed to objectively assess along with other psycho-physiological responses the state of arousal, emotions and as well as cognitive activity. The galvanic skin response can be graphed on a chart for observation, in the same way that heart or brain activity is recorded.
