Robert Burton's "Skeptic's Guide to the Mind" (BSP 96)

In On Being Certain: Believing You Are Right Even When You're Not, Robert Burton showed that the feeling of certainty, which is something we all experience, has its origin in brain processes that are both unconscious and inaccessible to consciousness . Now in his new book, A Skeptic's Guide to the Mind: What Neuroscience Can and Cannot Tell Us About Ourselves, he extends these ideas to other mental sensations such as our feeling of agency and our sense of causation.  The idea that much of what our brain does is not accessible to our conscious awareness is NOT new, but Dr. Burton considers the implications for our understanding of the MIND.

When we talked recently (BSP 96), Dr. Burton explained that his new book has two main parts.  In the early chapters, he extends the principles he developed in On Being Certain to other mental sensations. We tend to take things like our feeling of certainty, agency, and causation for granted, but he points out that these are generated in parts of the brain that we can neither access or control.  What makes A Skeptic's Guide to the Mind stand out is that Burton then explores the implications of this reality. He argues that while we can become ever more knowledgeable about how our brain works, the MIND, which is something that we each experience subjectively, is much more elusive.

The fact that we are trying to study the MIND with the MIND has inherent limitations and I think that Dr. Burton is right when he says our response should be HUMILITY.

Understanding Pain (BSP 95)

In Understanding Pain: Exploring the Perception of Pain,  Dr. Fernando Cervero does a wonderful job of condensing his 40+ years of research and immersion in the field of pain research into a concise but readable account.  It's a great introduction, and it's bound to inspire a new generation of physicians and researchers.

I interviewed Dr. Cervero in BSP 93, and this month's podcast (BSP 95) is the promised second part of our discussion of pain.  I focus on some of the topics that Dr. Cervero and I did not have time to discuss, including a look at how the mechanisms of acute pain differ significantly from those of chronic pain.  The growing appreciation of these differences offers hope to the millions of people around the world who suffer from chronic pain, but the ongoing efforts of researchers like Dr. Cervero also offer hope of improved pain relief for everyone.

Unfortunately, for those of you who love audiobooks, Understanding Pain, is not available in audio; but it is a relatively short book (under 200 pages) that I recommend to everyone.

Pain is a Complex Emotional and Sensory Experience (BSP 93)

Dr. Fernando Cervero  

Dr. Fernando Cervero of McGill University has been studying pain since the beginning of his career back in the 1960s.  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.

Neuroscience Highlights for 2012 (BSP 92)

The Brain Science Podcast recently passed 4 million downloads and it remains entrenched at or near the top of the iTunes rankings for Science and Medicine. So now it's time for our 6th Annual Review Episode. The purpose of this year-ending podcast is to review some of the year's highlights and key ideas. As I reviewed the transcripts of this year's episodes, I was struck by the fact that although each episode stands alone, they also inform one another. One unifying theme was the importance of taking an evolutionary approach to understanding how the human brain generates complex features like mind and consciousness.

Interviews have become an outstanding feature of the Brain Science Podcast. This year I interviewed 10 scientist, including five who have appeared in past podcasts.

The Origin of Emotions with Jaak Panksepp (BSP 91)

Dr. Jaak Panksepp

In his new book, The Archaeology of Mind: Neuroevolutionary Origins of Human EmotionsJaak 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 Archaeology 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.

Review of "Self Comes to Mind" by Antonio Damasio (BSP 90)

Episode 90 of the Brain Science Podcast is a discussion of Self Comes To Mind: Constructing the Conscious Brain, by Antonio Damasio. Damasio's book focuses on the answer to two key questions: How does the brain generate the Mind? and, How does the Brain generate Consciousness? His approach is unusual because many scientists and writers treat the Mind and Consciousness as identical. In contrast, Damasio argues that Mind precedes Consciousness. Listen to this podcast to learn how the Mind becomes Conscious.

Brain Aging Research with Dr. Pamela Greenwood (BSP 87)

Pamela Greenwood, PhD

Nuturing 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 (BSP 87)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 decline. Fortunately, even though normal brain aging is still not well understood, the discovery of brain plasticity 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 on dispelling the most stubborn myths about brain aging. We also talk about the practical steps we can all take to help maintain our cognitive performance.

Sebastian Seung Explores the Brain's Wiring (BSP 85)

Dr. Sebastian Seung

Dr. 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.

Update on Consciousness Research with Christof Koch (BSP 84)

Christof Koch, PhD

The 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.

How Mind Emerges from Brain (BSP 82)

In his latest book, Who's in Charge?: Free Will and the Science of the Brain, respected neuroscientist, Michael S. Gazzaniga, explores how the discoveries of neuroscience impact how we see ourselves as human beings.  After providing a brief review of 20th century neuroscience, and even some of the work from the past decade, Dr. Gazzaniga concludes that nothing neuroscience has discovered changes the fact that "we are personally responsible agents and are to be held accountable for our actions."

Gazzaniga's position contrasts with those who think that recent discoveries show that the brain creates the mind in solely "upwardly causal" way, and who argue that since much of what our brain does is outside our conscious awareness or control, we should not be held responsible for our actions.  Who's in Charge?: Free Will and the Science of the Brain presents what I think is a convincing argument against this common position.

In the latest episode of the Brain Science Podcast (BSP 82) I present a detailed discussion of Dr. Gazzaniga's book.

Brain Machine Interfaces (BSP 78)

In his book Beyond Boundaries: The New Neuroscience of Connecting Brains with Machines---and How It Will Change Our Lives neuroscientist Miguel Nicolelis puts his recent work with brain machine interfaces into historical context and explains why this work should change the way we understand how brains work.

Nicolelis challenges several long-standing assumptions including the primacy of the single neuron and strict localization, which is the idea that each area of the brain has a relatively fixed function.

Episode 78 of the Brain Science Podcast is a brief discussion of the key ideas presented in Beyond Boundaries, including a look at the implications of experiments such as the wide publicized work that culminated in demonstrating that a monkey in Nicolelis' lab at Duke (North Carolina, USA) could control a robot arm in Japan using only its brain.

Neurobiology of Placebos with Fabrizio Benedetti (BSP 77)

Fabrizio Benedetti, MD 

Dr. Fabrizio Benedetti is one of the world's leading researchers of the neurobiology of placebos.  In a recent interview (BSP 77) he explained to me that he believes that "today we are in a very good position to describe, from a biological and from an evolutionary approach, the doctor-patient relationship, and the placebo effect, itself."

To appreciate Dr. Benedetti's work, one must first realize that his approach differs from that of the typical clinical trial.  As he observed, "To the clinical trialist, a placebo effect means any improvement which may take place after placebo administration.  To the neurobiologist, a placebo response, or placebo effect means only something active in the brain happening after placebo administration: learning, anxiety reduction, activation of reward mechanisms."

In contrast, he explains, "The real placebo response, the real placebo effect is a psychobiological phenomenon.  It is something active happening in the brain after placebo administration: like learning, like anxiety reduction, and such like." Brain Science Podcast #77 provides an introduction to this complex, but fascinating topic.

Brain Networks with Olaf Sporns (BSP 74)

Olaf Sporns, PhD

Networks of the Brain by Olaf Sporns is an excellent comprehensive introduction to the use of Network Theory to study both the brain and the nervous systems of invertebrates.

In Episode 74 of the Brain Science Podcast, I interviewed Dr. Sporns (Indiana University) about some of the key ideas in his book.  Network Theory is becoming increasingly important as a tool for dealing with the massive amounts of data being generated by current techniques, such as brain imaging.  It is also a valuable tool for dealing with the fact that nervous systems consist of multiple scales (from the molecular level up to billions of neurons), which can not be reduced to a single scale.

While Networks of the Brain will be of greatest interest to those working in neuroscience and to those with a background in fields like engineering, mathematics, and computer science, this interview provides an introduction for listeners of all backgrounds.

Exploring Glial Cells with R. Douglas Fields (BSP 69)

Recent research has discovered that glial cells (the non-neuronal cells that make up about 85% of the cells in the human nervous system) actually do more than just support neurons.  In Episode 69 of the Brain Science Podcast, I explore some of these recent discoveries with pioneering researcher, R. Douglas Fields, PhD.  Dr. Fields is the author of The Other Brain: From Dementia to Schizophrenia, How New Discoveries about the Brain Are Revolutionizing Medicine and Science.  The Other Brain provides a compelling introduction to this exciting new field.  It is aimed at general readers, but it should also be on the must-read list for all students of neuroscience.

Affective Neuroscience with Jaak Panksepp (BSP 65)

Episode 65 of the Brain Science Podcast is an interview with Jaak Panksepp, PhD, author of Affective Neuroscience: The Foundations of Human and Animal Emotions.   Dr. Panksepp has done pioneering work on the neural origins of emotions.   In this interview, we discuss how his work challenges some of the common assumptions about emotions and some of the important implications of his discoveries.  New listeners may want to go back and listen to Episode 11 for an introduction to the neuroscience of emotion.
