David Eagleman talks about "the secret lives of the brain" (BSP 75)

In his new book Incognito: The Secret Lives of the Brain neuroscientist David Eagleman describes consciousness as "the smallest player in the operations of the brain" (page 5) because most of what the brain does is outside conscious awareness (and control). In a recent interview (BSP 75) Dr. Eagleman reviews some of the evidence for this startling position as well as the implications both for the average person and for social policy.

Brain Networks with Olaf Sporns (BSP 74)

Olaf Sporns, PhDNetworks 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 amaounts of data being generated by current techniques, such as brain imaging. It is also a valuable tool with 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.

Magic and the Brain (BSP 72)

BrainScience_itunes_600_blank.jpg

Neuroscientists Dr. Stephen Macknik and Dr. Susana Martinez-Conde have an unusual hobby: Magic! Actually, it is more than a hobby since for the last several years they have been working with leading magicians from around the world to create a new field: the neuroscience of magic. In Episode 72 of the Brain Science Podcast I talked with them about their new book Sleights of Mind: What the Neuroscience of Magic Reveals about Our Everyday Deceptions, which is the first book to explore the neuroscience of magic.

With the help of their co-author Sandra Blakeslee, Macknik and Martinez-Conde provide an excellent overview of this new and exciting field. Their book also provides an excellent review of many of the principles that I have introduced in the last 4 years.

Brain Science Podcast Returns

The latest  Brain Science Podcast (BSP 70) is an interview with Dr. Scott Lilienfeld, co-author of 50 Great Myths of Popular Psychology: Shattering Widespread Misconceptions about Human Behavior. This episode was recorded live at Dragon*Con 2010 in Atlanta, Georgia. We focused our conversation on the fact scientific reasoning and critical thinking do NOT come naturally. Instead, we all tend to make similar errors, such as mistaking correlation for causation. Dr. Lilienfeld shared his experiences and a extensive question and answer session with the live audience allowed him to explore additional examples.

New Discoveries about Glial Cells (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.

Another look a "The Myth of Alzheimer's" (B&I 36)

The Myth of Alzheimer's: What You Aren't Being Told About Today's Most Dreaded Diagnosis (2008) argues that we should re-evaluate our current approach to dementia. Earlier this month I posted an interview with the book's main author, Dr. Peter Whitehouse (BSP 68). Episode 36 of my Books and Ideas podcast is a follow-up interview with his co-author, Daniel George. As a medical anthropologist George helps put current attitudes into an historical perspective. Labeling  large numbers of older people with the diagnosis of "Alzheimer's Disease" is a relatively new practice and a closer examination of how this occurred provides an interesting example of how the history of medicine (and science) is interwoven with political and social history. While Whitehouse and George challenge the current approach to dementia, there message is actually one of hope. I am recommending The Myth of Alzheimer's to people of all ages.

"The Myth of Alzheimer's" with Dr. Peter Whitehouse (BSP 68)

Brain Science Podcast 68 is an interview with Dr. Peter Whitehouse, co-author (with Daniel George) of The Myth of Alzheimer's: What You Aren't Being Told About Today's Most Dreaded Diagnosis. Alzheimer's Disease originally referred to a relatively rare form of premature dementia, but in recent decades the diagnosis has been expanded to include patients of all ages. This change is not based on science and in this interview we talk about why being labeled with with Alzheimer's may be doing older patients more harm than good. Dr. Whitehouse is one of the pioneering researchers in this field, but advocates devoting resources to helping elders with with a wide range of age-related brain changes. This interview should be of interest to physicians, scientists, as well as patients and their families. I will be posting a supplemental interview with Daniel George, the co-author of The Myth of Alzheimer's later this month. (Learn more at /.)

Thomas Metzinger explores Consciousness (BSP 67)

The free podcast version of Brain Science Podcast 67 is now available. It is an interview with German philosopher Thomas Metzinger, author of The Ego Tunnel: The Science of the Mind and the Myth of the Self and Being No One. Dr. Metzinger argues that any credible model for how the brain generates the mind must incorporate unusual human experiences, such as so-called out of body experiences (OBE), and psychiatric conditions. In this interview we explore how OBE and virtual reality experiments shed light on how the brain generates the sense of self that characterizes normal human experience. listen-to-audio Listen to Episode 67 Click here for information about Premium Versions Subscribe to the Brain Science Podcast: itunes-badge-30 zunelogo-70 feed-icon32x32 mail-sticker-tiny Click here for detailed show notes and episode transcripts.

Memory and the Computational Brain with Randy Gallistel (BSP 66)

Episode 66 of the Brain Science Podcast is an interview with Randy Gallistel, PhD, Co-Director of the Rutgers Center for Cognitive Science and co-author (with Adam Philip King) of Memory and the Computational Brain: Why Cognitive Science will Transform Neuroscience. We discuss why read/write memory is an essential element of computation with an emphasis on the animal experiments that support the claim that brains must possess read/write memory. This is significant because current models, such as neural nets, DO NOT incorporate read/write memory in their assumptions about how brains work. It is not necessary to have any background in information theory or computation to appreciate the experiments that are discussed in this episode. Episode 3 and Episode 12 of the Brain Science Podcast provide  background information for this episode. listen-to-audio Listen to Free Podcast Click here for show notes and episode transcripts.

Bruce Hood, author of "SuperSense" (B&I 34)

Episode 34 of Books and Ideas is an interview with Bruce M Hood, author of SuperSense: Why We Believe in the Unbelievable.Dr. Hood is a developmental psychologist with a long-standing interest in why people believe weird things. In SuperSense he argues that innate cognitive structures (how we think without being taught) give people a natural tendency toward belief in the supernatural. Our intuitive sense of how the world works is often at odds with the findings of modern science. In this interview we discuss the evidence for these conclusions and their implications.
