Yes, but there are surprising cases where broad stimulation is effective, like deep brain stimulation for Parkinson’s disease or cochlear implants. It’s surprising that you don’t need perfectly targeted stimulation patterns to achieve a therapeutic output, but often times it does seem to have a benefit.

We think you can do much better for many applications with targeted stimulation, and that’s the direction that many of these implant technologies are heading. I’m a Neuroscientist working on BCI
