This image depicts cortical neurons derived from human induced pluripotent stem cells, labeled with antibodies against beta-tubulin III (Green). These cells were used to study the epilepsyassocated L1342P genetic variant of Nav1.2 voltage-gated sodium channels. Nuclei were labeled with DAPI (blue).
