Temporal regulation of progenitor lineage progression and output by NFIs underlying human neocortical malformation
Zhang et al. show that NFIs act as evolutionarily conserved global temporal regulators and bidirectionally control the pace of RGP lineage progression and consequently progeny output during neocortical development, providing direct insights into NFI mutation-associated human brain malformations.

Important paper: "The response profiles of neurons in different brain regions differ enough that a decoder can determine the region to which a particular neuron belongs." Sounds like the perfect antidote to the "everything is everywhere" view.
