Avoiding "Neuromania" (BSP 109)

/

I have spent the last 7 1/2 years sharing and promoting neuroscience and while it has been encouraging to see the field grow in popularity, there has also been a disturbing trend toward increased hype. One goal of the Brain Science Podcast is to provide accurate information that helps the average listener enjoy the science and avoid pseudoscience. BSP 109 was inspired by several excellent books that have documented the hazards of what some writers are calling "neuromania" or neurocentrism, which is the tendency to see the brain as the only path to understanding.

Consciousness as Social Perception (BSP 108)

/
Michal Graziano and Kevin

Michal Graziano and Kevin

In his latest book Consciousness and the Social Brain  Princeton neuroscientist Michael Graziano proposes a unique and compelling theory of consciousness. He proposes that the same circuits that the human brain uses to attribute awareness to others are used to model self-awareness. He emphasizes that his attention schema theory is only tentative, but it is testable and it does fit our current knowledge of brain function.

In a recent interview for the Brain Science Podcast (BSP 108), Graziano used the following clinical example to clarify his approach. A colleague had a patient who was convinced that he had a squirrel in his head. When confronted with the illogic of his claim the patient replied “Not everything can be explained by science.” In this example it is clear that the squirrel doesn’t really exist, so the question to be answered is HOW did his brain reach the conclusion that it does.

How to get this episode:

While imagining one has a squirrel in one’s head is thankfully rare, we also know that our subjective experiences of the world are not necessarily accurate. Our perception of the world is shaped by how our brain processes the sensory inputs it receives. For example, we perceive white light as an absence of color even though in reality it consists of all wavelengths.

Perception is something our brains do constantly and which we can not consciously control. In considering awareness (and by extension consciousness) perception-like Graziano is emphasizing several important features. The most important is probably the fact that it is only “quick and dirty model” of what is really going on, which means that our intuitions about consciousness are not necessarily reliable. In fact, humans have a strong tendency to over-attribute awareness to the world around us. This is part of the social circuitry that has made us the most successful species in the earth’s history, but it can also lead to amusing results (as anyone who has interacted with Siri on an iPhone has no doubt observed).

Another implication of considering awareness as a form of social perception is that it reverses the usual approach taken to understanding consciousness. Instead of asking how a physical brain can produce something subjective and non-physical called consciousness, we ask what kind of information processing leads to the conclusion that I (or anyone else) is conscious. As Graziano points out, this is a “mechanistic” model. Not only can it be tested but it has interesting implications. Dr. Graziano concluded that one of the key implications is "that awareness and consciousness are tools for information processing, and they are mechanistically understandable, and presumably can be engineered.”

I find the attention schema theory to be very compelling. Besides being testable, it has a simple elegance that I appreciate. It also explains why most humans experience a world filled with spirits, and are utterly convinced that their own consciousness is something special and non-physical.

Related Episodes:

Since understanding consciousness is one of the deepest questions facing neuroscience, it has been explored on many previous episodes of the Brain Science Podcast. Rather than list all those episodes I want to mention just a few that I think are particularly relevant to this month’s episode.

Sleep Science with Penny Lewis (BSP 107)

Penny Lewis

Penny Lewis

In The Secret World of Sleep: The Surprising Science of the Mind at Rest Dr. Penelope A. Lewis provides a highly readable account of the fascinating world of sleep research. Fascinating research is being carried out with animals as varied as fruit flies and rats, as well as with humans. I was surprised to learn that most people actually find it fairly easy to fall asleep in an fMRI scanner.

I have just posted an interview with Dr. Lewis (BSP 107) that includes a discussion of the role of sleep in memory as well as interesting findings about how synapses in the brain actually change during sleep. We still don't know exactly what sleep (and dreaming) are essential, but research in this field is growing. Dr. Lewis is excited about emerging research that suggests improving slow wave sleep may significantly improve learning and memory.

"The Cognitive-Emotional Brain" (BSP 106)

/
Luiz Pessoa of the University of Maryland

Luiz Pessoa of the University of Maryland

In The Cognitive-Emotional Brain: From Interactions to Integration neuroscientist Luiz Pessoa argues that emotion and cognition are deeply intertwined throughout many levels of the brain. In a recent interview (BSP 106) Pessoa and I focused on recent discoveries about the amygdala and Thalamus that challenge traditional assumptions about what these structures do. The amygdala processes more than fear (and other negative stimuli) and the Thalamus is more than  a mere relay station.

This a fairly technical discussion but Pessoa did a good job of making the material accessible to all listeners. The reason I think these concepts matter is that not only do they challenge overly simplistic notions of how the brain works, but they also challenge our tendency to see emotion and cognition as separate and often opposing processes.

Brain Plasticity with Michael Merzenich (BSP 105)

/
Michael Merzenich

Michael Merzenich

If you have read anything about brain plasticity you have seen the name Michael Merzenich. Dr. Merzenich is one of the pioneers in this field, having spent over 30 years documenting that the human brain (and that of other mammals) continues to change throughout life. I interviewed Dr. Merzenich several years ago (BSP 54), but the publication of his first book Soft-Wired: How the New Science of Brain Plasticity Can Change Your Life gave us another opportunity to talk about how we can apply these discoveries in our daily lives.

According to Dr. Merzenich, "No matter how much you've struggled, no matter where you've been in your life, you're in charge of your life going forward.  And you have the capacity; you have the resources to change things for the better—always have that capacity.  And that's what the book is trying to emphasize. “ (BSP 105)

I found Soft-wired very compelling because it combines a clear explanation of the science with many stories about real people facing a wide variety of cognitive challenges. The overall tone of the book is very optimistic even though it also considers the way bad choices can contribute to cognitive decline.

Connectome Update (BSP 103)

/
Olaf Sporns, PhD

Olaf Sporns, PhD

The Human Connectome is a description of the structural connectivity of the human brain, but according to Olaf Sporns, author of Discovering the Human Connectome, this description  must include a description of the brain's dynamic behavior. I first talked with Sporns back in BSP 74, but BSP 103 gave us a chance to talk about recent progress in connectomics.

Sporns sees the study of the brain's connections as fundamental to understanding how the brain works.

"It will allow us to ask new questions that perhaps we couldn’t ask before. It will be a foundational data set for us, just like the genome is. We will not be able to imagine neuroscience going back to a time when we did not have the connectome, but it will not give us all the answers.”

In his first book, Networks of the Brain, Sporns described how Network Theory provides important tools for dealing with the large data sets that are created by studying complex systems like the human brain.  In BSP 103 we discuss both the challenges and the promise of Discovering the Human Connectome.

Dangers of Diagnostic Inflation (BSP 102)

Allen Frances, MD

Allen Frances, MD

Americans are spending billions of dollars on psychiatric medications, but according to Dr. Allen Frances (Saving Normal: An Insider's Revolt Against Out-of-Control Psychiatric Diagnosis, DSM-5, Big Pharma, and the Medicalization of Ordinary Life) "We are ignoring the people who have severe psychiatric illness; so that, one-third of people with severe depression see a mental health clinician, two-thirds don't.  Two-thirds of people with severe depression get no treatment at all.  At the same time, we're way over-diagnosing people who have milder problems that would get better on their own."

Meanwhile, the drug companies push the prescribing of expensive new medications, while at least a million Americans are receiving their mental health care via the prison system. Allen argues "It shouldn't be that we deliver our psychiatric services to patients after we make them prisoners.  We should be getting the kind of community care and housing that's common in the rest of the world.  We're barbaric; we've gone back two hundred years, imprisoning psychiatric patients."

In BSP 102 Dr. Frances and I talk about the various factors that are driving these disturbing trends, including the over prescribing of psychotropic medications to young people without regard to the long term consequences. These are issues that concern us all, so I encourage you to listen to this interview and check out the additional references I have included below.

Synapse Evolution with Seth Grant (BSP 101)

/
Seth Grant (click photo to hear interview)

Seth Grant (click photo to hear interview)

Early in his career Seth Grant helped develop the transgenic mice that Eric Kandel used in his studies of how memory works. Since then he has combined his skill in genetics with his work on isolating the proteins that form the functional components of the synapse. (The synapse is a key component in the nervous systems of all multi-cellular animals.) When we last talked back in BSP 51 I was particularly struck by how many of these proteins actually evolved with single celled life--long before the arrival of nervous systems.

Recently Grant's work has focused on the discovery that the vertebrate synapse is actually much more complex than the one present in invertebrates. For BSP 101 we got together to talk about two papers he and his collegues recently published in Nature Neuroscience. These papers explore how small changes in the synapse proteins effect learning in measurable ways.

Grant has a special gift for making complex ideas clear, which means that this interview can be enjoyed by all listeners, even those who are new to the Brain Science Podcast and neuroscience.

Alvaro Fernandez of SharpBrains

I have been using the SharpBrains website as a source of information and ideas since the early days of my Brain Science Podcast, so it seemed fitting to invite SharpBrains co-founder Alvaro Fernandez to be my guest for Episode 100.   We talked about the second edition of The SharpBrains Guide to Brain Fitness: How to Optimize Brain Health and Performance at Any Age, which he co-authored with Dr. Elkhonon Goldberg (BSP 18). The goal of this book is to give people from all backgrounds a practical guide for evaluating the current science and establishing their own "brain fitness" regimen, much in the way that each of us must choose a physical fitness that meets our individual needs and lifestyle.

Brain Fitness should not just be a concern for older people, it should become a key component of a healthy lifestyle at any age. The SharpBrains Guide to Brain Fitness is a great first step.

Last month I posted a detailed discussion of Temple Grandin's latest book The Autistic Brain: Thinking Across the Spectrum (with Richard Panek), so I am pleased to share a follow interview with Dr. Grandin (BSP 99). This interview is different from the typical Brain Science Podcast because our focus is on the practical issues that face people who are dealing with autism. Of course, as Dr. Grandin emphasized, autism occurs across a wide spectrum ranging from those who can never learn to speak to high functioning professionals exemplified by Temple Grandin herself.  Dr. Grandin speaks from personal experience grounded in her own scientific curiosity.

"The Autistic Brain" by Temple Grandin (BSP 98)

/

 The Autistic Brain: Thinking Across the Spectrum  by Temple Grandin (with Richard Panek), is a tremendous gift, not just to patients and their families, but also to teachers, mentors, friends, and everyone who is interested in understanding how our brains make us who we are.

I think that this is a book everyone should read because as we come to appreciate the fact that the strengths and challenges of autism occur across a broad spectrum, we may also realize that some of these issues actually affect people who aren't considered autistic.  It is not the label that matters.  What does matter is recognizing that each of us has his or her own strengths and weaknesses, but thanks to brain plasticity, we all have the potential to nurture our strengths and, when necessary, accommodate our weaknesses.

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

/
​Robert Burton, MD

​Robert Burton, MD

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.

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.

2012-bama-crop.jpg

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.

The Origin of Emotions with Jaak Panksepp (BSP 91)

/
Jaak-crop.jpg

Dr. Jaak Panksepp

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 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.
