Researchers have developed a comprehensive spatiomolecular atlas of the human nucleus accumbens (NAc) by integrating single-nucleus and spatial transcriptomics. Their findings reveal that the anatomical layout of this brain region is defined by continuous transcriptional gradients and complex cell-type distributions rather than simple, binary boundaries. A key discovery includes the identification of evolutionarily conserved D1 islands enriched with the mu-opioid receptor, which serve as critical hubs for opioid and stress-related signaling. By applying transfer learning and genetic risk…
