Alterations in Circular RNAs circOprm1 and circSerpini in the Striatum are Associated with Changes in Spatial Working Memory Performance after Morphine Dependence and Withdrawal in Rats.

Modulating role of circRNAs and microRNAs in neurobiological changes induced by drug exposure remains unclear. We examined alterations in some circRNAs and microRNAs in the striatum after morphine dependence and withdrawal and their associations with the changes in spatial working memory performance. Male Wistar rats were used in which 10 days morphine exposure induced dependence.
