Single-nucleus RNA-seq of ~100,000 nuclei from rhesus macaque V1 and V4 reveals seven unique layer 4 subtypes in V1 and one in V4.
- Why it matters: High-resolution transcriptomic atlases that compare distinct macaque visual areas are lacking, limiting molecular links between cortical organization and visual processing.
- What they did: The BrainSPACE pipeline enabled rapid tissue banking from V1, V2, V4, MT, and TEO, followed by snRNA-seq and smFISH to map transcriptional gradients and validate layer-specific patterns.
- The result: smFISH-supported gradients align with ventral and dorsal stream hierarchies, and gene ontology highlights plasticity-related pathways in layer 4 subtypes, including NTNG1 and NLGN1 linked to neurodevelopmental disorders.
