Acute effects of neonatal dexamethasone treatment on proliferation and astrocyte immunoreactivity in hippocampus and corpus callosum: Towards a rescue strategy

► We investigated the possibility to block central effects of neonatal DEX-treatment. ► DEX-treatment acutely reduces hippocampal cell proliferation. ► DEX-treatment reduces glial activity one week post treatment. ► DEX-induced changes are partially prevented by central mifepristone pre-treatment.
