Abstract
Objective of this study was therefore to investigate the changes of human brainwaves using the available lightweight EEG devices, NeuroSky's Mindwave Mobile. Fifteen volunteers aged between 20–50 years participated in this study. The finding showed that delta and theta brainwaves gradually declined while alpha, beta and gamma brainwaves increased. Delta brainwave decreased after smoking with statistically significant at the 0.05 level. Similar to the delta brainwave, theta brainwave decreased with no statistical significant. On the other hand, alpha, beta and gamma brainwaves were found to be increased with statistically significant at the 0.05 level after smoking. In all of all of these brainwaves, Gamma brainwave increased highly after smoking compared to alpha and beta brainwaves. Similar to alpha brainwave, beta brainwave also increased. The results presented in this report clearly suggest that after smoking, it was found that delta and theta brainwaves were declined while alpha, beta and gamma brainwaves were increased. To our knowledge this is the first study to apply the effectiveness of commercially available lightweight EEG devices, NeuroSky's Mindwave Mobile, to investigate the human brainwaves of smokers. The data presented in this article indicate that it is important to apply this device to study the smoking habits.
