Genetically encoded cortical depletion Emx1-cre (JAX, B6.129S2-Emx1tm1(cre)Krj/J), Esco2fl/fl (JAX, B6N.129S-Esco2tm1.1Ge/J) and C57BL SCID (JAX, B6.Cg-Prkdcscid/SzJ) mice were used to generate the breeding scheme: male Esco2fl/flPrkdcscid/scid × female Emx1-cre+/−Esco2fl/+Prkdcscid/scid. Breeder and offspring cages were supplemented with breeder chow (Envigo Teklad 2919) and DietGel 76A (with plant protein) to help to increase pup survival. Some breeders were more prone to
