Eighteen teams analyzed the same neurophysiology dataset—and got wildly different answers

The “Brainhack” hackathon revealed that disagreement in neuroscience runs deeper than most researchers suspect—even in electrophysiology, a field that prides itself on hard data.

Reproducibility is a team sport: Lessons from a large-scale collaboration

Building reproducible systems across labs is possible, even in large-scale neuroscience projects. You just need rigor, collaboration and the willingness to look your own practices dead in the eye.

To improve big data, we need small-scale human imaging studies

By insisting that every brain-behavior association study include hundreds or even thousands of participants, we risk stifling innovation. Smaller studies are essential to test new scanning paradigms.
