To explore the possibility that genetic mouse models of ASD are associated with differences in neuronal and glial plasticity, we examined the number of new neurons and radial glia in the hippocampus, as well as the number, morphology, and reactivity of astrocytes and microglia in the hippocampus, mPFC, and striatum of Cntnap2 −/−, Shank3.
