The Mission to Get Breakthrough Brain Treatments to Everyone | Jacques Carolan of ARIA

Episode 3 of my new podcast features Dr. Jacques Carolan, a founding Program Director at ARIA, the UK’s Advanced Research and Invention Agency. He directs two neurotech programs aimed at one of the most important opportunity spaces: developing tools and systems to interface, at scale, with the human brain. One program is built on the idea that brain disorders are circuit problems, and funds tools to target those circuits with molecular precision across the whole brain. The other aims to deliver high-performance neurotech to the brain non-invasively or at most in a 30-minute outpatient procedure.We dig into the engineering and biology behind both programs, potential scaling unlocks for the field, how ARIA programs drive breakthroughs, Jacques background, the role of media in shaping the future, and much more. I hope you enjoy the conversation!Other links to this episode and references below.Sections00:00:00 Introduction 00:01:22 Why 20 years of neurotech breakthroughs haven't reached patients 00:04:08 The two variables that determine whether any medical technology gets adopted 00:09:17 Brain disorders cost the UK £100B/year and we're barely treating them 00:16:15 Using stem cells and gene therapy to build better brain interfaces  00:21:40 Self-regulating gene therapy that helps the brain quiet its own seizures 00:24:03 The non-technical reasons transformative neurotech fail to reach patients 00:31:34 Watching a 30-second brain ablation stop severe tremors00:38:11 The case for delivering brain implants and therapies without opening the skull00:50:56 Why high technical uncertainty makes distributed teams better than vertical integration 01:02:55 Why the UK keeps producing world-class neuroscience but not world-class neurotech companies 01:11:04 What AI-driven hypothesis generation means for breakthroughs per pound 01:20:40 From quantum computing to improv comedy to running £119M government brain programsLinks from the PodcastJacques CarolanWebsite: https://jacquescarolan.github.io/On X: https://x.com/jacquescarolanJacques’ Programs at ARIAARIA UKOpportunity Space Program 1: Precision NeurotechnologiesProgram 2: Massively Scalable NeurotechnologiesResearch Papers + Technical ReferencesPhysical principles for scalable neural recording (2013)How advances in neural recording affect data analysis (2011)Personalized brain circuit scores identify clinically distinct biotypes in depression and anxiety (2024)Predictive validity in drug discovery (2022)The “Sewing Machine” for minimally invasive neural recording (2019)Professor Gabriele Lignani on closed-loop gene therapy for epilepsyVideos + DemonstrationsDBS Tremor Surgery DemonstrationJohn Nelson on DBS for Depression at ARIA SummitReferences Mentioned in ConversationHarvard Designated Driver Campaign partnered with more than 160 TV shows, including Cheers and Dallas, helping popularize designated driving before Friends premiered in 1994 Mahnaz Avarneh — Neurotechnology Is InequityBooks + MediaThe Hitchhiker’s Guide to the Galaxy — Douglas AdamsThe Expanse — James S.A.
