Community & Citizen Science

Global Outreach & Citizen Science Initiatives

From crowdsourced retinal mapping to whole-brain consortiums: how citizen scientists, high school researchers, and global open-science consortia are illuminating the brain.

🎮 1. Citizen Science & Crowdsourced Mapping

Empowering hundreds of thousands of non-specialists and students to reconstruct neural circuits alongside top research institutes.

>250,000 Players

Developed by Sebastian Seung's lab (Princeton / MIT), EyeWire turned 3D retinal neuron reconstruction into a multiplayer web game. Players solve 3D puzzle cubes to color in dendritic branches of ganglion and bipolar cells.

Major Scientific Milestone: Citizen scientists discovered the circuit mechanism for motion direction selectivity in starburst amacrine cells (Nature 2014).

FlyWire Consortium →

Whole Adult Brain

A massive collaborative crowdsourcing effort connecting 280+ researchers across 76 global laboratories alongside community citizen scientists to proofread and curate the first complete connectome of an adult fruit fly brain (139,000 neurons, 50 million synapses).

Major Scientific Milestone: Complete whole-brain wiring diagram published as a flagship collection in Nature (2024).

🎓 2. Student & Workforce Training Programs

Preparing high schoolers, undergraduates, postbacs, and early-career scientists for authentic computational neuroscience research.

🧠 NeuroTrailblazers (NIH BRAIN CONNECTS)

A research-incubator training network supporting students and mentors across the BRAIN CONNECTS ecosystem. Provides an open technical curriculum (Units 01–09), a 2,000-paper OCAR literature graph, 25 teaching session kits, and hands-on capstone pathways.

🔬 Janelia Undergraduate & Visiting Scientist Programs

HHMI Janelia Research Campus offers intensive summer undergraduate research programs and visiting scientist fellowships. Scholars work directly with FlyEM and Project Technical Teams on FIB-SEM acquisition, proofreading, and machine learning segmentation.

HHMI Janelia • Summer Fellows • FlyEM

🌊 MBL Woods Hole Neurobiology Summer Course

The Marine Biological Laboratory's legendary neurobiology immersion course at Woods Hole, MA. Features hands-on modules in ultrastructural electron microscopy, electrophysiology, and connectomics graph theory.
