Kathryn Nave is a Leverhulme Trust Early Career Fellow at the University of Edinburgh, and the author of the book A Drive to Survive: The Free Energy Principle and the Meaning of Life. In the book, Kate dives deep into the free energy principle and active inference, which are popular approaches to studying brains, minds, and organisms in general, and which are being used in artificial intelligence. Ultimately, Kate finds these approaches come up short as explanatory frameworks for life, and autonomy, and intelligence. Instead, Kate and many others advocate a framework that Kate calls constraint closure or closure of constraints, but also goes by the name organizational closure. This is a concept from philosophy and theoretical biology that people like Alvaro Moreno and Matteo Mossio have put forth in their 2015 book Biological Autonomy. The core ideas are also found in various forms from people like Robert Rosen, Stuart Kauffman, Alicia Juarrero, Terrence Deacon, and others. We discuss what constraint closure is, why Kate thinks it's a solid foundation to build on, and what if anything it means for cognitive science and brain sciences to embrace this constraint closure view. I highly recommend the book even if you're looking for a primer on the free energy principle and active inference. As we discuss, Kate's journalism experience has helped her become a wonderful communicator of these notoriously difficult concepts.

Johannes Jaeger is Associate Faculty at the Complexity Science Hub in Vienna. He's also a freelance researcher, a philosopher, and an educator. He's here today to educate us about some of the fundamental differences between living organisms and machines, like AI, and why we should care about those differences. We discuss his paper The Cyborg Myth, an argument for why we can't seamlessly replace ourselves with machine parts over time. We talk about judgment and relevance realization as a fundamental difference between AI and living organisms -the ability to judge what is a relevant problem to solve in the first place, assuming intelligence is about problem solving. We also discuss what agency is in living systems, and why AI agents are something completely different. I think you get the recurring theme here. Yogi is writing a book called Beyond the Age of Machines, a work in progress and you can read it as he writes it on his expanding possibilities website.

Cristopher Moore is a professor at the Santa Fe Institute in New Mexico, and he is a computation and computational complexity expert. He recently joined a us in my complexity discussion group, and answered a bunch of our questions, but I wasn't done with him regarding what, if anything, computational complexity has to do understanding how brains and minds work. So that's why he's here today, and we discuss a wide variety of topics related to AI, computation, computational complexity, and cognition.

Neuroscience studies in part the relation between brain activity and behaviors. But, what is a behavior? It's a simple question, but there's no simple answer. For example, you're behaving right now, whatever you're doing, even if you're not doing much. When you cross the street, how many behaviors do you use? When you sleep, what behaviors do you do? Hopefully these simple examples make you think about how difficult it can be call some single movement a behavior.
Nedah Nemati is a philosopher of neuroscience at Columbia University. I met Nedah at a workshop a few months ago, where we chatted about the growing trend in neuroscience toward what is sometimes being called "naturalistic neuroscience," which really means varying levels of allowing organisms to behave more freely, less constrained, than traditional neuroscience experiments that seek to minimize unrelated to the behavior or cognition you want to isolate to study and explain. In more extreme cases, researches will try in the lab to emulate as much as possible the ecological world a particular organism has evolved to exist in, or even perform the experiments out of the lab, in the wild, so to speak. So a good part of our discussion revolves around this trend, and what counts as a "naturalistic" behavior, and how the tools we use to perform experiments shape the experiments and the scientific questions themselves.
Nedah has a neuroscience background, but in her philosophical work she has embedded herself into various neuroscience labs to better understand how the experiences of the researchers themselves, called their lived experiences, shape the assumptions and questions in their science. As an example, we discuss her work looking into the neuroscience of sleep from over a 100 years ago to today. When a modern neuroscientist studies sleep, are they studying the same thing a scientist claimed to be studying 100 years ago, even though they claimed to be studying sleep back then as well?

James Harrison is a clinical hypnotist, and author of a new book, Mental Foraging and the Evolution of Memory: An Updated Model of Clinical Hypnosis. As you probably know, hypnosis carries some historical baggage, for example, in terms of how it could be used to manipulate people into having false memories that could be damaging to themselves and those around them. That baggage carries over into modern medical and clinical practice, with many people giving the side eye to hypnosis and disregarding it as a useful tool in the toolkit of treating patients with mental disorders or psychological distress. As a clinician, and as someone who has seen clinical hypnosis work for people, James set about exploring how it might be explained in modern neuroscience terms and concepts. What he ended up with is an account of hypnosis grounded in the neuroscience of state changes, interoception, exteroception, and predictive processing. His hope is that if we get the scientific explanation right of how it works, hypnosis might become more accepted as an effective tool among other psychological treatments.

Acerca de Brain Inspired
Neuroscience and artificial intelligence work better together. Brain inspired is a celebration and exploration of the ideas driving our progress to understand intelligence. I interview experts about their work at the interface of neuroscience, artificial intelligence, cognitive science, philosophy, psychology, and more: the symbiosis of these overlapping fields, how they inform each other, where they differ, what the past brought us, and what the future brings. Topics include computational neuroscience, supervised machine learning, unsupervised learning, reinforcement learning, deep learning, convolutional and recurrent neural networks, decision-making science, AI agents, backpropagation, credit assignment, neuroengineering, neuromorphics, emergence, philosophy of mind, consciousness, general AI, spiking neural networks, data science, and a lot more. The podcast is not produced for a general audience. Instead, it aims to educate, challenge, inspire, and hopefully entertain those interested in learning more about neuroscience and AI.
