We're building a surgical robot capable of reaching any brain region. The goal: a generalized neural interface to help solve any condition that originates in the brain.

@ACNS_org Proud of you, Paul. I still remember your teaching and mentorship from 30 years ago. All the best!

Project Silica turns glass into a virtually eternal, immutable, high-density memory—designed to preserve humanity’s most important data for thousands of years.

@AndrewKnack Thank you for your kind wishes!

Bayes’ theorem is probably the single most important thing any rational person can learn. So many of our debates and disagreements that we shout about are because we don’t understand Bayes’ theorem or how human rationality often works. Bayes’ theorem is named after the 18th-century Thomas Bayes, and essentially it’s a formula that asks: when you are presented with all of the evidence for something, how much should you believe it? Bayes’ theorem teaches us that our beliefs are not fixed; they are probabilities. Our beliefs change as we weigh new evidence against our assumptions, or our priors. In other words, we all carry certain ideas about how the world works, and new evidence can challenge them. For example, somebody might believe that smoking is safe, that stress causes mouth ulcers, or that human activity is unrelated to climate change. These are their priors, their starting points. They can be formed by our culture, our biases, or even incomplete information. Now imagine a new study comes along that challenges one of your priors. A single study might not carry enough weight to overturn your existing beliefs. But as studies accumulate, eventually the scales may tip. At some point, your prior will become less and less plausible. Bayes’ theorem argues that being rational is not about black and white. It’s not even about true or false. It’s about what is most reasonable based on the best available evidence. But for this to work, we need to be presented with as much high-quality data as possible. Without evidence—without belief-forming data—we are left only with our priors and biases. And those aren’t all that rational.

Did you know that treating sleep apnea early may reduce the likelihood of a later Parkinson's diagnosis? Apnea describes brief pauses in breathing during sleep that can trigger drops in oxygen and potentially stress the brain. Neilson and colleagues describe in a new paper in JAMA Neurology that having obstructive sleep apnea elevated Parkinson disease risk and that early use of positive airway pressure may have lowered that risk. Key Points: - Obstructive sleep apnea increased the risk of later being diagnosed w/ Parkinson's as early as two years after diagnosis (of OSA) and the risk continued to rise through six years. - Early positive airway pressure treatment reduced Parkinson disease incidence, including in those w/ mild and severe sleep apnea. - Positive airway pressure was also linked to fewer falls, fractures, and lower mortality in those who later developed Parkinson's. My take: Do not ignore sleep when thinking about risk for later Parkinson's disease. This paper offers a compelling reason to identify and treat sleep apnea. Here are 5 points that resonated w/ me: 1- Sleep apnea matters for brain health, however many folks remain undiagnosed and untreated. 2- Early screening is critical since positive airway pressure showed protective effects when started w/in two years of sleep apnea diagnosis. 3- Positive airway pressure may modify a midlife risk factor that contributes to vulnerability for Parkinson's. 4- Treatment appeared to reduce harmful downstream consequences such as falls, fractures and early mortality. 5- Folks w/ Parkinson's and sleep symptoms should ask their health care providers about targeted screening and ways to improve night-time breathing. jamanetwork.com/journals/jaman… @ParkinsonDotOrg #parkinson @JAMANeuro @JAMA_current @movedisorder @uoregon @VeteransHealth
