This weekend, participants in the second annual Brainhack Eugene joined hundreds of others across four continents to work on innovative neuroscience projects. The event was organized by graduate students and postdocs in psychology and featured a 1-day workshop in open and reproducible neuroscience and a 2-day hackathon. During the hackathon, participants worked collaboratively on projects to: design an interactive power calculator for longitudinal MRI data, develop an fMRI-specific preregistration template, adapt a processing pipeline for 2-photo imaging data, implement reproducible workflows for MRI data preprocessing, develop a tool for automated motion artifact detection, and create an interactive art installation.
