Dopamine efflux in the rat nucleus accumbens evoked by dopamine receptor stimulation in the entorhinal cortex is modulated by oestradiol and progesterone.

This study compared the effects of dopamine receptor stimulation in the entorhinal cortex on dopamine release in the nucleus accumbens, measured by in vivo microdialysis in conscious Sprague-Dawley rats, with and without oestradiol and progesterone priming. Nonselective dopamine receptor stimulation with apomorphine reduced dopamine release in the nucleus accumbens, an effect which was prevented by injection of cis-flupenthixol into the entorhinal cortex. Selective D1 receptor stimulation with SKF38393 increased dopamine release, whereas selective D2 receptor stimulation with quinpirole did not affect dopamine release. Combined administration of oestradiol and progesterone potentiated the response to apomorphine and prevented the response to SKF38393. The effects of single hormone administration on the response to apomorphine suggested that the modulation was primarily due to oestradiol enhancing effects of progesterone. Experiments with high [K+] suggested these hormonal effects were exerted predominantly in the entorhinal cortex. The present experiments have demonstrated that dopaminergic modulation of transmission in a cortico-striatal loop linking temporal and prefrontal cortex is regulated by oestradiol and progesterone. Dysfunction in this system in humans may give rise to affective and cognitive symptoms which may, if initiated by a postpartum fall in oestrogen and progesterone concentrations, constitute the core pathophysiology of puerperal psychosis.[1]
