VEN Fatigue Hypothesis: Post-Presentation Update + GSEA Next Steps

Hi everyone,

Thank you to the @BrainAWG for having me present today at the meeting. Grateful for the warm reception, questions, and feedback from Windy, Nilufar, Ryan, and Amanda.

What I presented: The VEN Fatigue Hypothesis, Von Economo Neuron circuit degradation as a mechanism for the non-monotonic cognitive trajectory in long-duration spaceflight (early ERT improvement, late collapse at 340 days). Seven lines of convergent evidence across five independent datasets.

My two preprints:

Fast Lane Hypothesis (original SNN model, speed-accuracy tradeoff, FTD and autism): arXiv:2604.09229

VENCircuit (SNN training reliability, VENs as acquisition scaffolds, FTD and autism predictions): arXiv:2605.17399

Spaceflight paper (what I presented today, with Windy and Nilufar): preprint in preparation

Analysis code: github.com/esila-keskin/ven-spaceflight-cognition

Next steps from today’s discussion:

  • GSEA using Stat column from DGE tables (thank you Amanda)
  • Expanding longitudinal cognitive dataset
  • Extended SOMA atlas queries

Still looking for:

  • Longitudinal ERT or cognitive battery data beyond the Twins Study
  • DTI or fractional anisotropy data for ACC white matter in long-duration astronauts

Happy to collaborate. Feel free to reach out: esilakeskin06@gmail.com
