Maria Sundberg from the Boston Children’s Hospital, Harvard Medical School, and colleagues, recently reported in Nature Communications a study on the reciprocal copy number variations (CNVs) of 16p11.2 gene region, associated with a wide spectrum of neuropsychiatric and neurodevelopmental disorders. For the functional analysis of the developing iPSC-derived dopaminergic (DA) neuron network, complementary-metal-oxide-semiconductor (CMOS)-based high-density microelectrode arrays (HD-MEAs), MaxOne System by MaxWell Biosystems was extensively used. 16p.11.2 Reciprocal copy number variations (CNVs) in neuropsychiatric disorders 16p.11.2 CNVs have been implicated in…
