Of molecules and memories

1h 15m · Many Minds · 08 Feb 04:12

Where do memories live in the brain? If you've ever taken a neuroscience class, you probably learned that they're stored in our synapses, in the connections between our neurons. The basic idea is that, whenever we have an experience, the neurons involved fire together in time, and the synaptic connections between them get stronger. In this way, our memories for those experiences become minutely etched into our brains. This is what might be called the synaptic view of memory—it's the story you'll find in textbooks, and it's often treated as settled fact. But some reject this account entirely. The real storehouses of memory, they argue, lie elsewhere.

My guest today is Dr. Sam Gershman. Sam is Professor of Psychology at Harvard University, and the director of the Computational Cognitive Neuroscience Lab there. In a recent paper, he marshals a wide-ranging critique of the synaptic view. He makes a compelling case that synapses can't be the whole story—that we also have to look inside the neurons themselves.

Here, Sam and I first discuss the synaptic view and the evidence that seems to support it. We then talk about some of the problems with this classic picture. We consider, for example, cases where memories survive the radical destruction of synapses; and, more provocatively, cases where memories are formed in single-celled organisms that lack synapses altogether. We talk about the dissenting view, long lurking in the margins, that intracellular molecules like RNA could be the real storage sites of memory. Finally, we talk about Sam's new account—a synthesis that posits a role for both synapses and molecules. Along the way we touch on planaria and paramecia; spike-timing dependent plasticity; the patient H.M.; metamorphosis, hibernation, and memory transfer; the pioneering work of Beatrice Gelber; unfairly maligned ideas; and much, much more.

Before we get to it, one important announcement: Applications are now open for the 2024 Diverse Intelligences Summer Institute (or DISI)! The event will be held in beautiful, seaside St Andrews, Scotland, from June 30 to July 20. If you like this show—if you like the conversations we have and the questions we ask—it's a safe bet that you'd like DISI. You can find more info at disi.org—that's disi.org. Review of applications will begin on Mar 1, so don't delay.

Alright friends, on to my conversation about the biological basis of memory with Dr. Sam Gershman. Enjoy!

Consider the spider

Maybe your idea of spiders is a bit like mine was. You probably know that they have eight legs, that some are hairy. Perhaps you imagine them spending most of their time sitting in their webs—those classic-looking ones, of course—waiting for snacks to arrive. Maybe you consider them vaguely menacing, or even dangerous. Now this is not all completely inaccurate—spiders do have eight legs, after all—but it's a woefully incomplete and drab caricature. Your idea of spiders, in other words, may be due for a refresh.

My guest today is Dr. Ximena Nelson, Professor in the School of Biological Sciences at the University of Canterbury, in New Zealand. Ximena is the author of the new book, The Lives of Spiders. It’s an accessible and stunningly illustrated survey of spider behavior, ecology, and cognition.

In this conversation, Ximena and I do a bit of ‘Spiders 101’. We talk about spider senses—especially how spiders use hairs to detect the minutest of vibrations and how they see, usually, with four pairs of eyes. We talk about web-making—which, by the way the majority of spiders don't do—and silk-making—which all do, but for more reasons than you may realize. We talk about how spiders hunt, jump, dance, pounce, plan, decorate, cache, balloon, and possibly count. We talk about why so many spiders mimic ants. We take up the puzzle of “stabilimenta”. We talk about whether webs constitute an extended sensory apparatus—like a gigantic ear—and why spiders are an under-appreciated group of animals for thinking about the evolution of mind, brain, and behavior.

Alright friends, this one is an absolute feast. So let's get to it. On to my conversation with Dr. Ximena Nelson. Enjoy!

Can we measure consciousness?

A cluster of brain cells in a dish, pulsing with electrical activity. A bee buzzing its way through a garden in bloom. A newborn baby staring up into his mother's eyes. What all these entities have in common is that we don't quite know what it’s like to be them—or, really, whether it's like anything at all. We don't really know, in other words, whether they’re conscious. But maybe we could know—if only we developed the right test.

My guest today is Dr. Tim Bayne. Tim is Professor of Philosophy at Monash University in Melbourne, Australia. He’s a philosopher of mind and cognitive science, with a particular interest in the nature of consciousness. Along with a large team of co-authors, Tim recently published an article titled 'Tests for consciousness in humans and beyond.' In it, they review the current landscape of consciousness tests—or “C-tests”, as they call them—and outline strategies for building more and better tests down the road.

Here, Tim and I discuss what consciousness is and why theories of it seem to be proliferating. We consider several of the boundary cases that are most hotly debated right now in the field—cases like brain organoids, neonates, and split-brain patients. We sketch a few of the most prominent current consciousness tests: the command following test, the sniff test, the unlimited associative learning test, and the test for AI consciousness. We talk about how we might be able to inch our way, slowly, toward something like a thermometer for consciousness: a universal test that tells us whether an entity is conscious, or to what degree, or even what kind of conscious it is. Along the way, Tim and I talk about zombies, chatbots, brains in vats, and islands of awareness. And we muse about how, in certain respects, consciousness is like temperature, or perhaps more like happiness or wealth or intelligence, and maybe even a bit like fire.

I think you'll enjoy this one, friends—it's a thought-provoking conversation on a foundational topic, and one that takes us far and wide. So without further ado, here's my interview with Dr. Tim Bayne. Enjoy!

Rehabilitating placebo

Welcome back friends! Today we've got a first for you: our very first audio essay by... not me. I would call it a guest essay, but it's by our longtime Assistant Producer, Urte Laukaityte. If you're a regular listener of the show, you've been indirectly hearing her work across dozens and dozens of episodes, but this is the first time you will be actually hearing her voice.

Urte is a philosopher. She works primarily in the philosophy of psychiatry, but also in the philosophy of mind, the philosophy of biology, the history of medicine, and neighboring fields. She's particularly interested in a colorful constellation of psychiatric phenomena—phenomena like hypnosis, mass hysteria, psychogenic conditions, and (the topic of today's essay) the placebo effect.

There's almost certainly more to placebo than you realize—it's a surprisingly many-layered phenomenon. Here, Urte pulls apart those layers. She talks about what placebo can and cannot do, the mechanisms by which it operates, the ethical dimensions of its use, its evil twin nocebo, how it is woven through the history of medicine, and a lot more. She argues that, though we've learned a lot about the placebo in recent decades, we have not yet harnessed its full potential.

As always, we eagerly welcome your comments about the show. Feel free to find us on social media, or send us a note at [email protected]. We would love to hear your suggestions for future episodes, your constructive criticisms, really your feedback of whatever kind.

Alright friends, now on to our audio essay—'Rehabilitating placebo’—written and read by Urte Laukaityte. Enjoy!

Cosmopolitan carnivores

They tend to move under the cover of darkness. As night descends, they come for your gardens and compost piles, for your trashcans and attic spaces. They are raccoons, skunks, and coyotes. And if you live in urban North America, they are a growing presence. Whether you consider them menacing, cute, fascinating, or all of the above, you have to grant that they are quite a clever crew. After all, they've figured how to adapt to human-dominated spaces. But how have they done this? What traits and talents have allowed them to evolve into this brave new niche? And are they still evolving into it?

My guest today is Dr. Sarah Benson-Amram. Sarah is Assistant Professor of Forest and Conservation Sciences and Zoology at the University of British Columbia; she also directs the Animal Behavior & Cognition Lab at UBC. Sarah's research group focuses on the behavioral and cognitive ecology of urban wildlife. They ask what urban wildlife can teach us about animal cognition more generally and try to understand ways to smooth human-wildlife interactions.

Here, Sarah and I talk about her work on that trio I mentioned before: raccoons, skunks, and coyotes. These three species are all members of the mammalian order of carniovora, a clade of animals that Sarah has focused on throughout her career and one that has been underrepresented in studies of animal cognition. We discuss the traits that have allowed these species—and certain members of these species—to thrive in dynamic, daunting urban spaces. We also talk about the big picture of the evolution of intelligence—and how urban adapter species might shed light on what is known as the cognitive buffer hypothesis. Along the way, we touch on: the neophilia of raccoons and the neophobia of coyotes, puzzle boxes, the Aesop's fable task, hyenas and elephants, brain size, individual differences, human-wildlife conflict, comparative gastronomy, and the cognitive arms race that might be unfolding in our cities.

If you have any feedback for us, we would love to hear from you. Guest suggestions? Topics or formats you'd like to see? Blistering critiques? Effusive compliments? We're open to all of it. You can email us at manymindspodcast at gmail dot com. That's manymindspodcast at gmail. Though, honestly, if it's really an effusive compliment feel free to just post that publicly somewhere.

Alright friends, on to my conversation with Sarah Benson-Amram. Enjoy!

From the archive: Myths, robots, and the origins of AI

Hi friends, we're busy with some spring cleaning this week. We'll have a new episode for you in two weeks. In the meanwhile, enjoy this pick from our archives!

_____

[originally aired Nov 30, 2022]

When we talk about AI, we usually fixate on the future. What’s coming next? Where is the technology going? How will artificial intelligences reshape our lives and worlds? But it's also worth looking to the past. When did the prospect of manufactured minds first enter the human imagination? When did we start building robots, and what did those early robots do? What are the deeper origins, in other words, not only of artificial intelligences themselves, but of our ideas about those intelligences?

For this episode, we have two guests who've spent a lot of time delving into the deeper history of AI. One isAdrienne Mayor; Adrienne is a Research Scholar in the Department of Classics at Stanford University and the author of the 2018 book,Gods and Robots: Myths, Machines, and Ancient Dreams of Technology. Our second guest isElly Truitt; Elly is Associate Professor in the History & Sociology of Science at the University of Pennsylvania and the author of the 2015 book,Medieval Robots: Mechanism, Magic, Nature, and Art.

In this conversation, we draw on Adrienne's expertise in the classical era and Elly's expertise in the medieval period to dig into the surprisingly long and rich history of AI. We discuss some of the very first imaginings of artificial beings in Greek mythology, including Talos, the giant robot guarding the island of Crete. We talk about some of the very first historical examples of automata, or self-moving devices; these included statues that spoke, mechanical birds that flew, thrones that rose, and clocks that showed the movements of the heavens. We also discuss the long-standing and tangled relationships between AI and power, exoticism, slavery, prediction, and justice. And, finally, we consider some of the most prominent ideas we have about AI today and whether they had precedents in earlier times.

This is an episode we've been hoping to do for some time now, to try to step back and put AI in a much broader context. It turns out the debates we're having now, the anxieties and narratives that swirl around AI today, are not so new. In some cases, they're millennia old.

Alright friends, now to my conversation with Elly Truitt and Adrienne Mayor. Enjoy!
