The glucocorticoid receptor is a ubiquitous transcription factor mediating
adaptation to environmental challenges and stress. Selective Nr3c1 (the
glucocorticoid receptor gene) ablation in mouse dopaminoceptive neurons
expressing dopamine receptor 1a, but not in dopamine-releasing neurons, markedly
decreased the motivation of mice to self-administer cocaine, dopamine cell firing
and the control exerted by dopaminoceptive neurons on dopamine cell firing
activity. In contrast, anxiety was unaffected, indicating that glucocorticoid
receptors modify a number of behavioral disorders through different neuronal
populations.
