Effects of a brief mindfulness-meditation intervention on neural measures of response inhibition in cigarette smokers.

摘要: Research suggests that mindfulness-practices may aid smoking cessation. Yet, the neural mechanisms underlying effects of on are unclear. Response inhibition is a main deficit in addiction, associated with relapse, and could therefore be candidate target for mindfulness-based practices. The current study hence investigated brief mindfulness-practice response smokers using behavioral electroencephalography (EEG) measures. Fifty participants (33 females, mean age 20 years old) underwent protocol cigarette exposure to induce craving (cue-exposure) were then randomly assigned group receiving mindfulness-instructions or control-instructions (for 15 minutes approximately). Immediately after this, they performed Go/NoGo task, while their brain activity was recorded. At level, no differences observed. However, EEG analyses revealed decrease P3 amplitude during NoGo vs. Go trials mindfulness versus control group. lower might indicate less-effortful mindfulness-practice, suggest enhanced underlies observed positive behavior.
