Why Animal Emotions Matter (podcast)

Dr. Jaak Panksepp (click for audio)Episode 51 of Books and Ideas is actually a followup of Dr. Jaak Panksepp's recent interview on the Brain Science Podcast. There we talked in depth about the scientific evidence that humans share basic emotional circuitry with other mammals. In this interview we talk about the implications of this discovery,  focusing on how it should impact the treatment of laboratory animals. We also consider our relationships with pets and other domestic species.

  • Neuroscience of Pain (BSP 93)

    Click Logo to ListenDr. Fernando Cervero of McGill University has been studying pain since the beginning of his career back in the 1960's. These decades have seen tremendous advances in our neuroscientific understanding of what causes different types of pain as well as changing attitudes. Pain was once regarded as something that most people had to endure, but now most of us demand adequate pain relief, sometimes even to the point of not tolerating minor pain. Dr. Cevero's new book Understanding Pain provides an accessible account of both the history of pain research and a thoughtful consideration of the challenges facing the field.

    The latest episode of the Brain Science Podcast (BSP 93) is an interview with Dr. Cervero. This is Part 1 of a planned two part series.

    Ted Meisner: Secular Buddhism (podcast)

    Ted Meisner (click to listen)I recently had the opportunity to be a guest on The Secular Buddhist podcast, which is hosted by Ted Meisner. We talked about neuroscience and my new eBook Are You Sure? The Unconscious Origins of Certainty. I enjoyed learning about the Secular Buddhist Association, which is an outgrowth of the podcast, but I was surprised that listener feedback indicated that many listeners have a poor understanding of Buddhism and how it relates to Secularism. That is why I invited Meisner to come on my Books and Ideas podcast.

    I have just posted this interview as Episode 50:

    Where do Emotions Begin?

    Dr. Jaak Panksepp (click to play audio)In his new book The Archaeology of Mind: Neuroevolutionary Origins of Human Emotions Jaak Panksepp set out to make his life's work more accessible to a general audience. To be honest, reading this book requires a significant commitment, but I think he does a wonderful job of updating his classic textbook Affective Neuroscience. Anyone who is interested in this field will definitely want this book as a reference. The other strength of Archeology of Mind is its evolutionary approach. The primary emotional processes that Panksepp has spent his career studying have their origins in the ancient parts of the brain that are shared by all mammals. This contradicts longstanding assumptions in neuroscience, but it has important implications for both humans and other animals.

    In Episode 91 of the Brain Science Podcast Dr. Panksepp and I talked about some of the new information contained in Archeology of Mind with a particular focus on FEAR, which contrary to what many researchers claim, does NOT begin in the amygdala, but begins much lower. We do talk briefly about the experimental evidence, but this was covered in more detail during Dr. Panksepp's previous appearance on the Brain Science Podcast in BSP 65.

    Video Game Music with Emily Reese (Books and Ideas podcast)

    Emily Reese (Photo by Nate Ryan)Episode 49 of Books and Ideas is an interview with Emily Reese from Minnesota Public Radio. Reese is the host of two podcasts that I enjoy: Top Score and Learning to Listen. In this interview we focus on Top Score, which is a podcast about video game music. Reese interviews the composers and gives listeners an inside look at the challenges that face composers in this new, but growing field. You don't need to be a muscian or a gamer to enjoy Emily's podcasts.

    Brain Science Podcast with Evan Thompson (BSP 89)

    Evan Thompson, PhDEmbodied Cognition is a movement within cognitive science that argues that the mind is inseparable from the fact that the brain is embedded in a physical body. This means that everything that the brain does, from the simplest perception to complex decision-making, relies on the interaction of the body with its environment.  Evan Thompson's book Mind in Life: Biology, Phenomenology, and the Sciences of Mind is an in depth look at what he calls the "enactive" approach to embodied cognition. The enactive approach was pioneered by Thompson's mentor Francisco Varela and it emphasizes the importance of the body's active engagement with its environment.

    In a recent interview (BSP 89) I talked with Thompson about some of the key ideas in Mind in Life. Unlike most episodes of the Brain Science Podcast, this is not really a stand-alone episode. It is part of my ongoing exploration of both embodied cognition and the controverial topic of emergence. It is also intended as a follow-up to my recent interview with Terrence Deacon.

    Bruce Hood Returns (BSP 88)

    Bruce Hood, PhD

    The Self Illusion: How the Social Brain Creates Identity by Bruce Hood is a fascinating look at how our brains create both our experience of the world and our sense of being a single, coherent self. As the word "illusion" in the title indicates, neither is exactly what it seems. When I interviewed Dr. Hood (for BSP 88) he explained that The Self Illusion is a broad introduction to this somewhat surprising idea. The  Self Illusion was written with a general audience in mind. For those already familiar with the topic he also puts a new emphasis on the role of development. All readers should come away with a new appreciation for the critical role social interactions play through out human life.

    It was fun to talk with Dr. Hood again. I first interviewed him for Books and Ideas #34. At that time we discussed his first book, SuperSense: Why We Believe in the Unbelievable.

    How Storytelling Makes Us Human (podcast)

    Jonathan GottschallWhat do fiction, dreams, and children's make believe have in common? Why is storytelling found in every human culture? These are among the fascinating questions explored in The Storytelling Animal: How Stories Makes Us Human by Jonathan Gottschall.

    I have just posted an interview with Jonathan Gottschall (Books and Ideas #48) in which we talk about some of the key ideas in his new book. Gottschall's goal is to look for clues about why storytelling is such an universal behavior. He also argues that it should be possible to form testable theories about the purpose of storytelling.

    Brain Aging Update (BSP 87)

    Pamela Greenwood, PhDNuturing the Older Brain and Mind by Pamela M. Greenwood and Raja Parasuaman provides a comprehensive review of the current research in cognitive aging.  In the latest Brain Science Podcast  Dr. Greenwood explains that brain aging and cognitive aging are not the same thing; the typical brain changes that are associated with normal brain aging (such as shrinkage) are not reliable predictors of cognitive declince. Fortunately, even though normal brain aging is still not well understood, the discovery of brain plasiticity is shifting the focus of research. Not only does brain plasticity offer new hope for people who suffer strokes and other brain injuries, it also suggests that life style choices influence cognitive function at all ages.

    Nurturing the Older Brain and Mind is intended for an academic audience but it is accessible to everyone. This month's interview with Dr. Greenwood (BSP 87) focuses is on dispelling the most stuborn myths about brain aging. We also talk about the practical steps we can all take to help maintain our cognitive performance.

    "Incomplete Nature" with Terrence Deacon (podcast interview)

    Terrence Deacon, PhDIn his new book Incomplete Nature: How Mind Emerged from Matter Terrence Deacon writes that his goal is “demonstrate how a form of causality depending specifically on absent features and unrealized potential can be compatible with our best science.” (page 16). But in a recent interview (Books and Ideas #47) he also contends that his book "grew out of a dissatisfaction with the systems theory approach." He feels strongly that "to understand the origin of end-directed phenomena, representational phenomena, or mental phenomena, you need to take one further step; you need to figure out what’s beyond self-organization that needs to be explained to account for these things." Thus, his ambitious goal is to find a place for meaning within in science.

    Incomplete Nature is a dense but compelling book, and the goal of this interview is to introduce listeners to the idea that life and meaning are compatible with a scientific world view.

    Disgust with Rachel Herz (BSP 86)

    Disgust is an universal emotion, but unlike emotions like fear and anger, disgust must be learned. This is the main conclusion of Dr. Rachel Herz's latest book That's Disgusting: Unraveling the Mysteries of Repulsion. In a recent interview (BSP 86) Dr. Herz told me why she spent the last several years studying this rather unusual subject. We also discussed what the study of disgust can tell us about how our brains process emotion.

    This is Dr. Herz's second visit to the Brain Science Podcast. Back in BSP 34 we talked about her first book The Scent of Desire: Discovering Our Enigmatic Sense of Smell.

    Sebastian Seung, author of "Connectome" (BSP 85)

    Dr. Sebastian SeungDr. Sebastian Seung (MIT) is an ambitious young scientist; his goal is to unravel the entire wiring diagram of the human brain. Considering that it took over a decade to determine the wiring diagram for the roundworm C elegans, which has a mere 302 neurons, it is clear that scientists can't leap directly to the 80 billion neuron human brain. Even so, in his new book Connectome: How the Brain's Wiring Makes Us Who We Are, Seung makes a very good argument for the value of this long term project. In Episode 85 of the Brain Science Podcast I talked with Dr. Seung both about the challenges and potential benefits of this work.

    Christof Koch returns to the Brain Science Podcast

    Christof Koch, PhDThe scientific study of consciousness was once viewed with skepticism, but this has changed dramatically in recent years. According to pioneering neuroscientist Christof Koch, "the great thing is we’re not condemned to just sort of philosophical speculation, but we can make some predictions, and then go out and measure them.  And those are the things I talk about in this book, Confessions of a Romantic Reductionist." In Brain Science Podcast #84 Koch reflects on the progress that has been made since I interviewed him back in 2007 (BSP 22), and he also talks about the latest initiatives at the Allen Institute for Brain Research, where he as recently become the chief science officer.

    William Uttal on "Mind and Brain" (BSP 83)

    William Uttal, PhD"There is nothing more exciting than the mind/brain problem" according to Dr. William Uttal, author of Mind and Brain: A Critical Appraisal of Cognitive Neuroscience. In the latest episode of the Brain Science Podcast (BSP 83) I talked with Dr. Uttal about why he feels that brain imaging can not solve this mystery. First, there is the problem that brain imaging represents the wrong level of analysis because every spot you see on a brain scan actaully represents thousands of neurons. This means that the activity and interaction between individual neurons has been lost. Then there is the problem of reproducibility, with divergent results between studies. The evidence is accumulating that "much of the brain responds to any stimulus, and every area of the brain participates in multiple functions." This means that asking where a given function occurs may be the wrong question.

    BSP 83 represents an on-going discussion of these issues, so I have included links to related episodes in the show notes.

    Philosopher Patricia Churchland returns to the Brain Science Podcast

    Patricia Churchland (photo by Nines Minequez)BSP 81 marks the return of philosopher Patricia Churchland, who I first interviewed back in Episode 55. Our recent conversation focuses on her latest book, Braintrust: What Neuroscience Tells Us about Morality. We discuss the historical background and contrast Churchland's approach to that of Sam Harris in The Moral Landscape. Then Professor Churchland discusses how recent discoveries in neuroscience are shedding light on the evolutionary origins of morality.

     

    It's a fascinating conversation that you won't want to miss.

    Exploring Alabama with Roger Reid (BI 46)

    Roger ReidRoger Reid has a job that every kid and most adults would find fascinating. He works for the Alabama Museum of Natural History and travels all over Alabama as a writer and producer for the Emmy Award winning TV show, Discovering Alabama with Dr. Doug Phillips . He also shares his passion for natural history in a series of novels written for middle school age readers. I decided to interview him for Books and Ideas because I wanted to share these novels with my listeners. They combine mystery and science in an original way, but they also contain compelling characters that readers will care about.

    Episode 46 of Books and Ideas is an unusual episode because we don't just talk about Reid's novels. We also explore some of the little known treasures of Alabama's natural history. I guarantee surprises, even for those of you who call Alabama home. But I also hope that listeners around the world will gain a new appreciation for the natural resources of Alabama.

    Karen Traviss on Writing for Gears of War (BI 44)

    Karen TravissThe thing that draws me to novels by Karen Traviss is her characters and her recent series of novels based on the popular Gears of Wars videogame delivers a character-driven story of surprising depth. In fact, even though the recently released game Gears of War 3 (also written by Traviss) brings the games to an end, Traviss is still working on the 5th and final Gears of War novel, which is scheduled for release next spring.

    I was fortunate to interview Traviss last month, shortly after the release of Gears of War 3. The interview is spoiler free, but even if you don't play video games this interview will give you a new insight the role of writing in this emerging genre.

    Cognitive Dissonance with Carol Tavris, PhD (Books and Ideas #43)

    Carol Tavris, PhD Click for audioThe theory of cognitive dissonance is not new but Mistakes Were Made (But Not by Me): Why We Justify Foolish Beliefs, Bad Decisions, and Hurtful Acts by Carol Tavris and Elliot Aronson makes cognitive dissonance accessible to everyone, and, more importantly, Tavris and Aronson make it clear why we should care. As Dr. Tavris explained in a recent interview (Books and Ideas #43), "cognitive dissonance is a theory of blind spots." Appreciating how our brains automatically strive to decrease the discomfort we feel when faced with conflicting beliefs, can help us become aware of how these blind spots effect our behavior and attitudes.

    Cognitive dissonance is also revelevant to anyone with an interest in science because as Dr. Tavris noted: "the scientific method is designed to create dissonance—in a way, we could say this.  This is one of the reasons science is so unpopular—I should say is so difficult—because scientists are humans, and scientists don’t like it when their predictions are disconfirmed.  But, you see, as we now understand, the mind is designed for consistency, for consonance; it’s designed to notice, and remember, and confirm evidence that supports our beliefs, and to forget and ignore information that is dissonant with our beliefs.

    It’s such an interesting thing for those of us interested in skepticism and science, because the scientific method is designed to create dissonance—in a way, we could say this.  This is one of the reasons science is so unpopular—I should say is so difficult—because scientists are humans, and scientists don’t like it when their predictions are disconfirmed.  But, you see, as we now understand, the mind is designed for consistency, for consonance; it’s designed to notice, and remember, and confirm evidence that supports our beliefs, and to forget and ignore information that is dissonant with our beliefs."
