    • I met a neurologist today who is working with something called Open Brain Computer Interface.

      I had to Google that because what it meant to me was "Open Source Brain Computer Interface". Turns out, my interpretation was exactly what it is. I was kinda shocked because, well, that's the world of neurologists and here there are people who want you and I to be involved. You can find the source on GitHub. And you can buy your own kit to experiment with. OpenBCI's home is here.

      The neurologist I met is working on ways to better control seizures. Others are working on control over prosthetic devices. Still others are working on ways to improve the lives of patients with ALS or other paralyzing disease.

      Some of the challenges with control include measuring neurons firing at different rates, positioning of sensors in the brain (not included in the Pro Kit :)) and even the spacing of neurons.

      It's amazing to me that scientists are putting things like this out there for people to work with and it's pretty cool to see what's come from the work and imagine what will come for those who've lost the ability to use a limb or become paralyzed through some spinal cord injury.

      Wait, what?! This looks like something I should have seen at Maker Faire. Looks like lots of sensing equipment to pick up electrical signals from the brain, then I wonder what you make of all that data?

    • Yeah. I would have expected Maker Faire too.

      No idea how to interpret the data either. But I wonder if that's not a benefit for the right someone. I think maybe something like amateurs in Astronomy who discover planets or make fantastic astro photographs. Like Jimmy Walker.

      I'm a neuroscientist who works in a BMI lab, so I feel obligated to comment here! I work with electrode data measuring electrical activity of individual neurons, not amalgamated local field potentials that EEG picks up, but large-scale data analysis is basically my job. Here's some basic descriptions of EEG processing that quick vetting suggested was valid. As for this company, I'm not really understanding how they are doing anything other than marketing things by using neuroscience buzzwords, but if you were an EEG neuroscience (which takes years of training to analyze data, usually in the form of a phd) then I guess you could do some fun stuff with these at home kits. I tend to try to not promote content like this that is essentially overhyping EEG as a BMI. The resolution is very low and the results inferred from data collected in poorly controlled experiments is typically useless. Reverse inference-ing ( is generally a terrible idea, and while open-sourcing tools to analyze data is great, selling things that people can't typically generate valid conclusions from isn't).

    • Glad you've chimed in.

      For me, the "promise" is more in things like prosthetic control or working to mitigate seizures or giving pt's with some form of paralysis a chance.

      I'm pretty sure the Pro Kit isn't gonna help in that regard but maybe it'll help people understand what's at stake?
