This presentation outlines the findings from our paper published in Genes (2026). We investigated gene expression changes in the mouse cortex during Sleep Deprivation (SD) and Recovery Sleep (RS) using a fully data-driven approach.
Key Highlights:
• Methodology: Utilized Tensor Decomposition (TD)-based unsupervised feature extraction to identify gene expression patterns without prior hypotheses.
• Discovery: Identified distinct expression patterns where genes failed to normalize or "overshot" baseline levels during recovery sleep, contrary to traditional assumptions.
• Biological Insight: Enrichment analysis revealed that Somatostatin (Sst)-expressing neurons play a critical role in regulating sleep deprivation and recovery.
• Validation: Findings were validated using AlphaGenome, a generative AI, confirming that Sst enrichment is supported by genomic sequence predictions.
