EyeWire’s J Day: The Official Launch

EyeWire launches today with J Day!

It’s time to mobilize a global community of citizen neuroscientists to trace the 3D structure of J Cells and understand how retinal connectomes relate to visual perception.

J Cell, EyeWire, neuron, 3D, Seung Lab, MIT NeuroscienceA specific type of retinal neurons called J Cells respond to stimuli that move downward on the retina (which is the same as upward in the visual world). Neuroscientists do not currently understand how the neural circuits of the retina cause the J Cell to respond in this way. That’s one of the reasons we built EyeWire. By playing EyeWire, you map the 3D structure of retinal neurons and their connections, and collaborate with neuroscientists at MIT, the Max Planck Institute for Medical Research, and Harvard.

Over the past several months, members of Sebastian Seung’s lab at MIT have been hard at work making sure EyeWire allows users to accurately contribute to research. During our beta period, an average of 30 to 50 people played EyeWire each day.  Collectively, EyeWirers have mapped over 160,000 individual cubes since the beta went live in spring. We hope to dwarf these numbers in the coming months.

Below check out a short video from Sebastian Seung, who shares why we created EyeWire and how you can get involved.

Today is J Day, the start of a revolution in neuroscience. We ask that you play EyeWire for 10 minutes per day and share EyeWire with friends. In order to make the great scientific leaps necessary for us to understand the brain’s higher functions, we must prove that citizen science can impact neuroscience in the same way that it has impacted fields like astronomy and biology.


In the coming months, we will release new features, including interactive updates and fun game dynamics that will enhance your EyeWire experience.  Subscribe to this blog and connect with us on Facebook to be the first to know about EyeWire news.


We are thrilled to welcome you into the EyeWire community. In the words of Sebastian Seung, “the quest to understand the brain is the greatest adventure of our time.” In order to understand the extraordinarily beautiful and complex brain, we need something more intelligent than the most powerful supercomputer — you.  Join us on this epic journey. Play EyeWire and help trace the wires of perception.


Here at EyeWire HQ we are so stoked about the brain that we created a fun, one minute theatrical trailer.  Enjoy!
