A conserved population of genetically defined striatal neurons gates opioid reward https://www.biorxiv.org/content/10.64898/2026.07.28.741269v1

Our new preprint from @daylab.bsky.social characterizes Chst9-MSNs, a specialized NAc population with high Oprm1 expression and opioid sensitivity that is required for fentanyl reward learning. Excited to share this work! 🧠🧬 www.biorxiv.org/content/10.6...
