Serotonergic neurotransmission in the ventral hippocampus is enhanced by corticosterone and altered by chronic amphetamine treatment

▶Corticosterone stimulates hippocampal serotonin release via glucocorticoid receptors. ▶Chronic amphetamine decreases glucocorticoid receptors in the hippocampus. ▶Chronic amphetamine attenuates corticosterone-induced hippocampal serotonin release.
