The frequency and amplitude of mIPSCs are lower in V1 layer 2/3 of wild-type mice after 3 d binocular enucleation (light blue trace) than after normal rearing (black). This effect is absent in mice lacking RARα in parvalbumin-expressing neurons (light green, normally reared; dark green, after enucleation). See Zhong et al. for details.
