ISDP Celebrates 40 years of Neuroscience Research

I am in Washington, DC to cover Neuroscience 2008, the annual meeting of the Society for Neuroscience; but yesterday, thanks to Kathleen Burke, PhD, of USC, I also had the opportunity to visit a poster session at the International Society of Developmental Psychobiology (ISDP), which is celebrating it 40th year.  The focus of the ISDP is on the relationship between brain developmental and behavior.  This is an area of research that has many practical applications.

For example, it is well-known that excessive alcohol consumption in pregnancy can cause the devastating condition known as fetal alcohol syndrome.  Researchers are trying to uncover the mechanisms of this damage.  They are also trying to determine whether there are any countermeasures, such as iron-supplementation, that really help prevent the damage.

The research topics are quite diverse.  They range from questions about how babbling relates to language development to questions about adolescent brain.  Jack Turman, PhD, arranged for me to talk to numerous researchers, and I hope to have some of them on a future episode of the Brain Science Podcast.  You can learn more about ISDP at http://www.isdp.org/

Brain Evolution with Gary Lynch, PhD (BSP 48)

Episode 48 of the Brain Science Podcast is an interview with Gary Lynch, PhD, co-author (with Richard Granger) of Big Brain: The Origins and Future of Human Intelligence.  Dr. Lynch has spent decades studying memory at the level of the synapse.  His work with computer simulations based on how the brain really works led him to a fascination with the question of how our brains got so large.  Are humans smart because we have big brains or because are brains are different?

Dr. Lynch argues that the unique features of the human brain are a natural result of increased brain size.  He also argues against the conventional view that increasing brain size resulted from selection pressures during the millions of years of primate evolution that proceeded the emergence of homo sapiens.  We talk about the evidence supporting this radical position during the interview.

We also talk about another radical theory that Dr. Lynch has proposed, which is the idea that the olfactory cortex formed the template for the evolution of the cortex in mammals and primates.  This intriguing theory brings a new perspective to the fact that the olfactory system has unique access to important brain systems including the frontal lobes, the amygdala (which is involve in emotion), and the hippocampus (which is essential to long-term memory.

In addition to discussing the evidence that led him to his controversial theories, Dr. Lynch discusses the challenges facing scientists interested in pursuing research questions about brain evolution.

"All in the Mind" Looks at Brain Plasticity

Recently Natasha Mitchell did an excellent two-part All in the Mind  podcast about brain plasticity.  In Part 1, she interviewed Jeffrey Schwartz, MD and Norman Doidge, MD.  Dr. Schwartz is the author of The Mind and the Brain: Neuroplasticity and the Power of Mental Force, and Dr. Doidge wrote the recent bestseller,The Brain That Changes Itself: Stories of Personal Triumph from the Frontiers of Brain Science.

In Part 2, Mitchell interviews Dr. Doidge further.  One of the topics they explore is the "dark side" of plasticity.  Since neuroplasticity is a dynamic, competitive process, it is actually a factor in how we form our habits, both good and bad . This interview is an excellent follow-up to the interview Dr. Doidge did for the Brain Science Podcast back in Episode 26.

Brain Imaging: Recorded LIVE at Dragon*Con 2008 (BSP 46)

Dr. Campbell at Dragon*Con 2008

Brain Science Podcast #46 is a discussion of brain imaging with Dr. Shella Keilholz and Dr. Jason Schneiderman.  The focus of our discussion is functional magnetic resonance imaging (fMRI), which is revolutionizing neuroscience.  We talked about both the strengths and weaknesses of this technique.  Both of my guests agree that mainstream coverage of this technique tends to exaggerate what we can actually tell from this kind of brain scan.  An important principle is that the scan of any single individual can vary greatly from day to day, which means that valid conclusions require data from a large number of people.

Since this episode was recorded LIVE in the Podcasting Track at Dragon*Con 2008, it includes audience questions at the end, which helped bring out additional ideas.  I have posted an edited version (but there is still some noise from the room next door).  If you are interested in hearing the raw unedited version, click here.  I also want to thank Swoopy from Skepticality for all the work she did to make the podcasting track a great success.

More about my guests:

Shella Keilholz, PhD, is an assistant professor of Biomedical Engineeering at Georgia Tech and the Emory School of Medicine in Atlanta, GA.  She is doing studies that involve correlating fMRI scans with the reading from electrodes placed in rat brains.  This work is fundamental to improving the correlation between fMRI scans, which reflect brain activity only indirectly, and what is actually happening in the neurons of the brain.

Jason Schneiderman, PhD studied psychology before earning his PhD in neuroscience.  His dissertation involved the use of diffusion tensor imaging, which is a new method of scanning that is being used to track the axonal connections in the brain.  He is currently doing a post-doctoral fellowship at Harvard Medical School, where his team is trying to determine if the connections in the brains of young schizophrenics are different from normal.  The goal is to improve early diagnosis because early intervention makes a big difference.

John Ratey, MD Discusses ADD (BSP 45)

Have you ever wondered why a child with ADD can play videos games for hours, but can't concentrate on his homework for a few minutes?  This is one of the paradoxes of attention-deficit disorder that John J Ratey, MD, co-author of, Driven To Distraction : Recognizing and Coping with Attention Deficit Disorder from Childhood Through Adulthood, explains in Episode 45 of the Brain Science Podcast.

During this interview, Dr. Ratey discusses the latest findings about the biological basis of what he calls "attention variability disorder."  He also offers practical advice for patients and parents dealing with ADD/ADHD.  One very important, and somewhat surprising, fact that he shares is that patients who are treated with medications during adolescence have a significantly lower risk of developing problems with addiction and drug abuse later on compared to those who are not treated.  Also, successful "ADD-ers" like Michael Phelps show that "having a mission" makes a huge difference.

Dr. Ratey's most recent book is Spark: The Revolutionary New Science of Exercise and the Brain, which he discussed with me (Dr. Campbell) in Episode 33.

Note: Insight Meditation is based of vipassana meditation, the mindfulness practices of Theravada, the oldest branch of Buddhism.  Insight Meditation is easily adapted to secular purposes because it not based on beliefs or dogmas.  The most well-known secular form is called mindfulness meditation, which begins with a focus on breath awareness and then advances to developing compassion for oneself and others.

Researchers are studying people who practice other types of mediation also. Richard Davidson has focused his work on the study of Tibetan Buddhist monks.  Their practice emphasizes the development of compassion.

From SharpBrains: Neurogenesis and Brain Plasiticity

In her latest post for SharpBrains™ Laurie Bartels reviews some of the principles of brain plasticity.  One principle that she mentions that I think deserves more attention is the importance of learning new things.

Adults may have a tendency to get set in their ways – I’ve been doing it this way for a long time and it works, so why change?  Turns out, though, that change can be a way to keep aging brains healthy.  At the April Learning & the Brain conference, the theme of which was neuroplasticity, I attended several sessions on adult learning. (Click here to read Laurie's post.)

Don't Miss Neuroscience Pioneer, Dr. Brenda Milner, on Futures in Biotech

In Episode 33 Futures in Biotech  host Marc Pelletier, PhD, interviews pioneering researcher, Dr. Brenda Milner from the Montreal Neurological Institute.  Dr. Milner is best known for her work with HM, the patient that she worked with for many decades.  Her work helped neuroscientists appreciate the role of the hippocampus in memory and the fact that there are multiple types of memory, some of which do not require the hippocampus.

One of the things that makes this interview special is that Dr. Milner gives us the inside story on some of the pioneering work that we now take for granted.  She emphasizes how the work fit into the context of its time, giving an unique glimpse into the history of how science really unfolds.

Review: "On Being Certain" (BSP 42)

Episode 42 of the Brain Science Podcast is a discussion of On Being Certain: Believing You Are Right Even When You're Not, by Robert Burton, MD.  This Part 1 of a two-part discussion of the unconscious origins of what Dr. Burton calls "the feeling of knowing."  In Episode 43 I will interview Dr. Burton. Today's episode provides an overview of Dr. Burton's key ideas.

In past episodes I have discussed the role of unconscious decision-making.  On Being Certain: Believing You Are Right Even When You're Not ,by Robert Burton, MD, takes this topic to a new level.  First, Dr. Burton discusses the evidence that the "feeling of knowing" arises from parts of our brain that we can neither access or control.  Then he discusses the implications of this finding, including the fact that it challenges long-held assumptions about the possibility of purely rational thought.

"The Psych Files" Explores the "Mozart Effect"

Dr. Michael Britt of The Psych Files podcast has just completed an excellent two-part discussion of the so-called Mozart Effect.  With his guest, Dr. Kenneth Steele, he examines the origins of this popular idea, as well as the fact that no one has replicated the original research that suggested such an effect might exist.  If you have ever wondered whether listening to classic music could make you (or your baby) smarter, you will want to listen to this podcast.  Also, check out his blog for a full list of references.
