A recent cluster of reports have considerably deepened our understanding of the transcriptional diversity of serotonin neurons of the dorsal raphe nucleus (DR). In this commentary a subset of implications from these studies is highlighted such as: serotonin neurons in the lateral wings have a newly discovered close relationship with those in rostral and dorsal locations and that cre-lines may be just as likely to cut across several transcriptional subtypes as to define a single subtype. To evolve understanding of DR organization, it may be prudent to correlate transcriptional snapshots in time with other known features of DR neurons. Here we bring together new and old information on serotonin neuron diversity with the goal of developing increasingly useful schemes of DR organization.

中缝背组织

最近的一组报告大大加深了我们对中缝背核 (DR) 血清素神经元转录多样性的理解。在这篇评论中，强调了这些研究的一个子集，例如：侧翼中的血清素神经元与喙和背侧位置的血清素神经元有新发现的密切关系，并且 cre-lines 可能同样可能跨越几种转录亚型以定义单个子类型。为了加深对 DR 组织的理解，将转录快照及时与 DR 神经元的其他已知特征相关联可能是谨慎的。在这里，我们汇集了有关血清素神经元多样性的新旧信息，目的是开发越来越有用的 DR 组织方案。
