OXT and autism: Recently, Lewis et al. (2020) have particularly targeted oxytocin neurons through SMART-Seq2 in combination with molecular targeting approaches and revealed that some autism risk genes, such as Calb1, Kcnmb4, Reln, and Cnr1, are enriched in parvocellular oxytocin neurons in comparison to magnocellular oxytocin neurons in the context of parallel processing circuits.
