AIMS This study's purpose was to identify the neural substrates and mechanisms responsible for craving among subjects with alcohol use disorders (AUDs) using functional magnetic resonance imaging (fMRI). METHODS Alcohol abusers with AUD (n = 9) and demographically similar non-abusers (n = 9) participated in this study. After given 5 cc of alcohol,(More)
The aim of the study was to examine the differences of boredom, pain, and surprise. In addition to that, it was conducted to propose approaches for emotion recognition based on physiological signals. Three emotions, boredom, pain, and surprise, are induced through the presentation of emotional stimuli and electrocardiography (ECG), electrodermal activity(More)
This study aimed to investigate the differences in brain functions during verbal working memory between individuals with alcohol use disorders (AUD) and normal controls. fMRI was used to scan brain activations associated with verbal working memory while participants performed 2-back and 0-back tasks. A total of 21 young male college students participated in(More)
Alcoholism is associated with abnormal anger processing. The purpose of this study was to investigate brain regions involved in the evaluation of angry facial expressions in patients with alcohol dependency. Brain blood-oxygenation-level-dependent (BOLD) responses to angry faces were measured and compared between patients with alcohol dependency and(More)
Diabetes is an incurable chronic disease with the prevalence high in developed countries. The number of patients in Korea is also on a steady increase. Patients have to self-manage their blood glucose level by daily test and insulin injection. Therefore, it is very important to assist them in self-management procedure. In this study, PDA(personal digital(More)
Emotions are complex processes involving multiple response channels, including physiological systems, facial expressions and voices. Bio-signals reflect sequences of neural activity, which result in changes in autonomic and neuroendocrine systems induced by emotional events. Therefore in human-computer interaction researches, one of the most current(More)
Assisting diabetes patients to self manage blood glucose test and insulin injection is of great importance for their healthcare. This study presented a PDA based system to manage the personal glucose level data interfaced with a small glucometer through a serial port. The data stored in the PDA can be transmitted by cradle or wireless communication to the(More)
Extraversion is a personality frequently discussed as one of the strongest and most consistent factors that relates to individual subjective wellbeing. The goal of this study was to better understand how people with varying degrees of extraversion psychologically and physiologically respond differently to unpleasant circumstances. Emotional responses (e.g.,(More)
Very little is known about the neural circuitry underlying anger processing among alcoholics. The purpose of this study was to examine the altered brain activity of alcoholic individuals during transient anger emotion. Using functional magnetic resonance imaging (fMRI), 18 male patients diagnosed with alcohol dependence in an inpatient alcohol treatment(More)
