Age dependent differences in the regulation of hippocampal steroid hormones and receptor genes: Relations to motivation and cognition in male rats

Abstract Estrogen and estrogenic functions are age-dependently involved in the modulation of learning, memory and mood in female humans and animals. However, the investigation of estrogenic effects in males has been largely neglected. Therefore, we investigated the hippocampal gene expression of estrogen receptors α and β (ERα, β) in 8-week-old, 12-week-old and 24-week-old male rats. […]
