Cortical GABAergic interneurons in rodents originate in three subcortical regions: the medial ganglionic eminence (MGE). the lateral/caudal ganglionic eminence (LGE/CGE) and the preoptic area (POA). Each of these neuroepithelial precursor domains contributes different interneuron subtypes to the cortex. nNOS-expressing neurons represent a heterogenous population of cortical interneurons. https://allfixelectricales.shop/product-category/copper-tube-bending-pliers/
