description Stall Catchers Overview
Stall Catchers is a citizen science game developed by EyesOnALZ that engages volunteers in Alzheimer's disease research. Players examine video footage of mouse brain capillaries to identify 'stalls'—locations where blood flow is blocked or reduced, which researchers associate with Alzheimer's disease progression. By crowdsourcing this analysis, the project accelerates data processing for scientists studying the relationship between vascular health and neurodegeneration.
help Stall Catchers FAQ
What do you do in Stall Catchers?
Players examine movies of real mouse-brain blood vessels and classify each vessel as flowing or stalled. The results are combined with other players' annotations to help Cornell researchers study blood-flow problems linked to Alzheimer's disease.
Who created Stall Catchers?
Stall Catchers was developed by the Human Computation Institute as part of the EyesOnALZ project. Its research collaborators include Cornell University's Schaffer-Nishimura Lab and the team behind the stardust@home volunteer platform.
When did Stall Catchers launch?
The game launched in October 2016. It was designed as an online citizen-science project so people without laboratory training could contribute annotations to Alzheimer's research data.
Do I need scientific experience to play Stall Catchers?
No, the game includes an introduction and is designed for ordinary volunteers rather than trained microscopists. Its website says each vessel is analyzed by multiple catchers, and the crowd result is used to improve reliability.
