Non-targeted and Targeted Metabolomics Techniques Reveal Striatal Metabolome Characteristics in the Ketamine-Induced Conditioned Place Preference Mice Model.

Journal of molecular neuroscience : MN July 12, 2025 Weihao Fan, Yi Ye, Hongkun Yang et al. 1 citation

Ketamine, originally developed as an anesthetic, is now being studied for depression treatment, but its addictive potential is a growing concern. This research used a mouse model of ketamine-induced conditioned place preference (CPP) to investigate changes in the striatum, a brain region involved in reward. Advanced metabolomics techniques revealed that ketamine abuse alters striatal metabolites, affecting pathways related to arginine synthesis, purine metabolism, and morphine addiction. Specifically, ketamine increased the neurotransmitter kynurenine (Kyn) and decreased dopamine (DA) in the striatum. These disturbances in Kyn and DA metabolism may underlie the addictive behaviors seen in the CPP model, offering new insights into ketamine addiction mechanisms.

Where Spirits Still Speak: Chinese Mass Shamanism and the Unfinished Project of Modernity

Highlights in Art and Design May 28, 2026 Yiming Sun

Shamanism has gained growing popular attention in China despite the state's official secularism. Through analysis of literary works, documentaries, social media, and interviews, the paper shows how artistic representations aestheticize and simplify shamanism. It argues that Chinese mass shamanism is a cultural response to structural and affective predicaments of contemporary China, including instrumentalism in diffused religion, social atomization, and the erosion of 'the nearby'. The phenomenon is presented as a hybrid formation born of modernity's failure to achieve complete disenchantment, situating it within modernity's entanglement with occultism.
