Pyramidal neurons of the cerebral cortex display marked layer- and subtype-specific differences in their axonal projections and dendritic morphologies. Here we show that transcription factor Zfp312 is selectively expressed by layer V and VI subcortical projection pyramidal neurons and their progenitor cells. Knocking down Zfp312 with small interfering RNAs(More)
Cortical excitatory glutamatergic projection neurons and inhibitory GABAergic interneurons follow substantially different developmental programs. In rodents, projection neurons originate from progenitors within the dorsal forebrain, whereas interneurons arise from progenitors in the ventral forebrain. In contrast, it has been proposed that in humans, the(More)
Fragile X syndrome (FXS), the leading monogenic cause of intellectual disability and autism, results from loss of function of the RNA-binding protein FMRP. Here, we show that FMRP regulates translation of neuronal nitric oxide synthase 1 (NOS1) in the developing human neocortex. Whereas NOS1 mRNA is widely expressed, NOS1 protein is transiently coexpressed(More)
