Heart rate (HR) and electrodermal activity (EDA) are often used as physiological measures of psychological arousal in various neuropsychology experiments. In this exploratory study, we analyze HR and EDA data collected from four participants, each with a history of suicidal tendencies, during a cognitive task known as the Paced Auditory Serial Addition Test (PASAT). A central aim of this investigation...
Optical brain monitoring using near infrared (NIR) light has got a lot of attention in order to study the complexity of the brain due to several advantages as oppose to other methods such as EEG, fMRI and PET. There are a few commercially available functional NIR spectroscopy (fNIRS) brain monitoring systems, but they are still non-wearable and pose difficulties in scanning the brain while the participants...
Suicide, considered as one of the leading causes of death, has not been given enough attention in order to reduce it's rate. The problem addressed in this paper is the analysis of the relation between an extra stimulus and physiological data's responses. In order to record the physiological data set from multiple subjects over many weeks, we used an acoustic startle during a Paced Auditory Serial...
Copious amounts of people around the globe currently suffer from ailments in moving, which range from neurodegenerative diseases to colossal accidents. In this study, oxygenated hemoglobin of the brain is monitored using a functional near infrared spectroscopy coupled with a smart watch to detect kinetic activity. It was seen that as participants flipped their left or right hands, at different speeds,...
