Cue reactivity is a key factor in modulating motivational and goal-directed behaviors associated with compulsive drug intake and relapse. Smoking-associated cues produce smoking urges and cravings and are accompanied by the activation of brain regions involved in attention, motivation, and reward. We investigated whether acupuncture ameliorates cravings(More)
Measures of cue reactivity provide a means of studying and understanding addictive behavior. We wanted to examine the relationship between different cue reactivity measures, such as attentional bias and subjective craving, and functional brain responses toward smoking-related cues in smokers. We used eye-tracking measurements, a questionnaire for smoking(More)
OBJECTIVES Cue reactivity is a key factor that modulates motivational goal directed behavior associated with compulsive drug intake and relapse. We investigated the effect of acupuncture on the selective attention to smoking-related visual cues in smokers, as an index of the severity of drug dependence. METHODS Twenty-nine smokers received real(More)
OBJECTIVES In smokers, smoking-associated cues produce smoking urges and cravings, which are accompanied by autonomic dysfunction in response to these cues. We investigated whether or not acupuncture ameliorated cigarette withdrawal symptoms, as well as attenuated the autonomic responses to smoking-related visual cues in smokers using a power spectrum(More)
Nicotine, like several other abused drugs, is known to act on the reward system in the brain. Smoking-associated cues produce smoking urges and cravings accompanied by autonomic dysfunction to these cues in smokers. The present study was aimed at investigating whether cues related to smoking elicit the autonomic response in smokers. The subjective and(More)
OBJECTIVES In this study, we investigated the short term effects of acupuncture on autonomic control of blood flow in healthy subjects. We also studied whether deqi (obtaining qi) sensations are correlated with these autonomic hemodynamic changes. METHODS The experiment had a randomized, crossover design. Five healthy volunteers (age: 18-26 years)(More)
This study compared verum acupuncture (VA) and sham acupuncture (SA) stimulation by assessing autonomic and subjective responses. Autonomic responses such as skin conductance response (SCR) and heart rate (HR) were measured. Subjective pain ratings were collected and evaluated. A correlation analysis was performed for SCR and HR changes and subjective pain(More)
Background. While therapeutic acupuncture perception (deqi) has recently been investigated only for the subject's perception, classical acupuncture discussed acupuncture perception for both the practitioner and the subject. The aim of this study was to explore the practitioner's and the subject's acupuncture perception during acupuncture. Methods.(More)
OBJECTIVES The present study aimed to determine whether health service advertisements are perceived differently depending on advertising conventional or complementary and alternative medicine clinics. METHODS A total of 42 adults (male=21, female=21) recruited through advertisements in Seoul, South Korea participated in this study. A standardized health(More)
The present study examined whether health information is judged differently depending on pre-existing beliefs and expectations. People's initial beliefs and expectations were assessed by a questionnaire about acupuncture and a trustworthiness and preference rating task of doctors' faces. Then, newspaper headlines about novel acupuncture treatment were shown(More)
