为什么戒烟容易失败？科学家可能发现了原因。据PNAS上发表的一篇论文，大脑的一组神经元可能通过在戒烟期间增加对尼古丁的响应破坏戒烟的努力。他们发现，尼古丁乙酰胆碱受体（nAChRs）的α3、β4和α5亚单位在尼古丁复吸方面起到了关键的作用。科学家研究了小鼠在戒断尼古丁期间的这些亚单位和调控尼古丁渴求的神经信号之间的相互作用，发现当接触过尼古丁的小鼠进行尼古丁戒断并且重新接触尼古丁时候，神经活动增加到了原来的两倍以上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
