	abstract = {<p>The vertebrate brain develops through a precisely orchestrated sequence of events, where neural progenitors generate neuronal diversity. However, the importance of stem cell origin in the acquisition of functional characteristics and the assembly into circuits are largely unknown. Here, by multimodal cell lineage reconstruction we reveal a link between progenitor origin and excitatory and inhibitory activity in the hindbrain. By combining progenitor intersectional fate mapping with newly developed computational tools and CRISPR/Cas9-based loss-of-function experiments, we discovered the differential temporal contribution of distinct progenitor pools {\textendash}defined by proneural gene expression{\textendash} to both glutamatergic and GABAergic neurons. Whereas neurog1-progenitors contribute to both lineages in early embryonic stages, later, other progenitor pools either also assume this role or take over. Using calcium imaging in combination with genetic perturbations, we unveiled that spatiotemporally defined stem cell origin determines specific neuronal activity features. Overall, we provide in vivo evidence for a link between cell ontogeny and functionality in the vertebrate hindbrain.For more information or any specific tool, you can contact us.</p>
