GRIA1 and congenital rubella syndrome: Consistently with data presented here and our previous findings showing a cocaine-triggered increase of GluR1 subunit of AMPA receptors (AMPARs) in the NAcore of CRS-exposed animals (Esparza et al., 2012; Rigoni et al., 2021), an enduring structural remodeling in the NAcore, but not the NAshell, was observed (Figures 3B–K).
