Abstract

In this issue of Cell Stem Cell, Wang et al.<sup>1</sup> generate human nucleus basalis of Meynert organoids (hnbMOs), establish a human-specific cholinergic projection system in transplanted assembloids, and identify projection deficits in Down syndrome-derived assembloids. This study provides a valuable model for investigating nbM-related neural circuits and neurological disorders.
