Today's guest is from Blackrock Microsystems. While we've featured Blackrock guests before, Stephen's appearance today is driven by his podcast, , where neurotech-inspired movies are reviewed and discussed. Top 3 Takeaways: "Our goal for the podcast isn't necessarily to be overly technical, requiring a neuroscience degree to understand. We're often deep in the subject matter and may get a bit jargony, but broadly, we aim to be accessible without pretending to be accomplished neuroscience researchers." “Due to the subject's nature, movies dealing with neuroscience themes...

is a University of Michigan PhD graduate working on thin film neural implants but has since transitioned into the legal side of things having passed his bar exam and working with . This interview took almost 2 years to get done but we're glad we were able to do it! Top 3 Takeaways: "I think the main thing I'll say is you don't undermine your valuation by not having an informed and intentional patent strategy, and you don't have to go cheap. You know, I feel that you have to bootstrap, but if you work with certain law firms that are very entrepreneurial friendly, and my...

"Welcome to today's episode! Our guest, , co-founder and CEO of , brings innovation to neural implants. With roots in France and a Harvard PhD, he's leading groundbreaking work. Welcome, Paul!" Top 3 Takeaways: "It's a good time to ask the question: What if we could develop solutions tailored for this problem instead of borrowing from the semiconductor industry? That's what Axsoft is about. We emphasize developing soft materials that offer better long-term biocompatibility. Additionally, these materials are suitable for micro and nano fabrication and remain stable inside the...

Today’s guest is who is a share who works in regenerative neural tissue engineering. Top 3 Takeaways: "We're trying to create scaffolds that can be templates for the body to repair itself, to grow around, and ultimately become natural tissue, seamlessly integrating with the body's own." "Other faculty were discouraging. This is because academia tends to prioritize scholarly pursuits such as papers and grants, often undervaluing applied work and its real-world applications." "Our clinical collaborator actively participated in the lab alongside Sarah. Together, they would work on...
info_outlineE.J. Chichilnisky is a Professor of Neurosurgery and Ophthalmology at Stanford University. His research has focused on understanding the spatiotemporal patterns of electrical activity in the retina that convey visual information to the brain, and their origins in retinal circuitry, using large-scale multi-electrode recordings. His ongoing work now focuses on using basic science knowledge along with electrical stimulation to develop a novel high-fidelity artificial retina for treating incurable blindness.

Top 3 Takeaways:
- "The basic 3 steps of the device are to 1) read the spontaneous activity that's there and use that to identify the different cells and different cell types; 2) pass current through each of the many electrodes (a thousand electrodes in the first device) to figure out which electrodes activate which cells and how much; and 3) finally translate that according to the “scores" we have for the different cell types into patterns of activity. This is way more complicated than any neural interface that's been designed."
- "Plasticity in the brain is not there just because the brain wants to be plastic. It's there because it's evolutionarily valuable to have a plastic circuit. If you think about it from an electronics point of view, a plastic circuit is costly."
-
"Our understanding of the retina is 30 years ahead of our understanding of the brain. That's not because retina neuroscientists are smarter – it's because the retina is more accessible and easier to understand. So our understanding in the retina always precedes our understanding of the cortex."
0:45 "Do you do you wanna introduce yourself?"
1:30 "So how did you get into this?"
3:45 "What is your proposal versus how things were being done before?"
9:45 What are the 20 types of retinal cells?
14:30 "What's is this a specific design of the device? And then what's your role in this as well?"
17:30 "Are you guys working with other companies in the field too?"

20:00 Are cortical implants more or less sensitive to your 'orchestra' approach?
26:15 "What are some of the biggest challenges in this or if you had unlimited funding, what would you throw that funding at first"
35:00 "How are you interfacing with these different cell types?"
38:30 " That all sounds very tedious. And especially if you're talking about thousands of electrodes, is this done by hand, or is this the poor graduate student that has to do this? Or is there a way to automate it?"
43:15 "What are some timelines that we can expect with this technology?"
44:30 "What's the difference between you and Dr. Palanker?"
46:15 "Is there anything that we didn't talk about that you wanted to mention?"
