🎯 Goal: 50 responses by Nov 7 — the survey takes just 3 minutes.
Every response helps us map how science becomes innovation.

Thanks for supporting this project by Koliane, Sarah and me 🙏

4/ This is the final work from my PhD journey. Grateful to my collaborators, the Max Planck Institute for Biological Intelligence, and anonymous reviewers for their support and feedback along the way.

3/ Key highlights:
- Over 9,900 genes (~64% of the genome) were differentially expressed.
- 98% of these changes were transient during the first 2 weeks of song development.
- Testosterone drove brain plasticity, enabling male-like songs.

2/ 🧠 In this study, we show how testosterone transforms non-singing female canaries into vocal performers by triggering gene expression changes in the HVC, a song-controlling brain area.
