Reading and Rewriting the Brain

What if a person who can’t speak could still be heard? In this talk, I’ll share how speech neuroprostheses (brain-machine interfaces that read neural activity) aim to turn intended words into text or voice. I’ll explain how we record speech-related brain signals, what "decoding" means, and how large language models (LLMs) can help make predictions more accurate and natural. We’ll discuss what works today, current challenges, and what this could mean for people with paralysis.

Join us for a fascinating journey as we unpack the intricate neurobiology linking Down syndrome and Alzheimer’s disease—two conditions that tell a profound story of the brain. As life expectancy dramatically increases, we’re discovering that nearly all individuals with Down syndrome will face the challenge of Alzheimer's by age 40. This talk will delve into the complexities of brain changes, neuropsychological impacts, and the potential for early interventions. Discover how understanding these connections enriches our perspective on cognition, resilience, and the human experience!

What if we could treat mental health, restore memory, or improve longevity, by directly interacting with the brain’s circuits? Neurotechnology is making this possible. In this talk, Stanford neuroscientist Derrick Buchanan introduces the rapidly growing field of neurotechnology—from brain stimulation and brain computer interfaces to AI-powered brain mapping. Join us and learn how scientists are beginning to read and influence brain activity, and how these technologies may transform the future of medicine and mental health.
