This podcast's purpose is to bring together the field of neuroprosthetics/brain machine interfaces/brain implants in an understandable conversation about the current topics and breakthroughs.

We hope to replace needing to read scientific papers on new research in an easy to digest way.

People can share thoughts or ideas to facilitate 'idea sex' to make the field of brain implants a smaller and more personal space.

Dr Josh Siegle is a senior scientist working at the Allen Institute working on large-scale electrophysiology using tools like the Neuropixels probe. He is also heavily involved in the design and distribution of Open Ephys which is an open-source electrophysiology tool.

Top three takeaways:

  • "The dark matter problem is where the number of cells that we record is almost always less than the number of cells that we actually know to be in the tissue around the electrodes. This could be because there are neurons near the electrodes that just don't fire action potentials, their action potentials look very similar to other nearby neurons, or maybe the listening radius of our electrodes is not quite as large as we would expect it to be."
  • "A big advantage of working at the Allen Institute is that we have very generous internal funding from Paul Allen. And so although we do apply for grants when it makes sense, for most people at the Allen Institute,  getting grant funding is not an existential threat to their research."
  •  Open Ephys has recently started offering virtual 1-on-1 training sessions to help people get up and running with their tools. This is aligned with their goal of making open-source tools even more accessible throughout the neuroscience community.
