Classics never get old: neurotransmitters shape human cortical interneuron migration.

Abstract

While key developmental functions of neurotransmitters have been described in rodent neural progenitors, there is a lack of understanding of their roles in the human fetal brain. A new study published in The EMBO Journal demonstrates that human cortical interneurons that are moving in fused brain organoids express a large repertoire of neurotransmitter receptors whose activation fine tunes selective migration strategies.
