Brain Science Podcast #51: Seth Grant on Synapse Evolution

Episode 51 of the Brain Science Podcast is an interview with Dr. Seth Grant from Cambridge University, UK. Dr. Grant's work focuses on the proteins that make up the receptors within synapses. (Synapses are the key structures by which neurons send and receive signals.) By comparing the proteins that are present in the synapses in different species Dr. Grant has come to some surprising conclusions about the evolution of the synapse and the evolution of the brain.

Books and Ideas Podcast #22: Dragon*Con 2008

Episode 22 of Books and Ideas is my summary of my recent trip to Dragon*Con 2008 in Atlanta, Georgia. It was a great opportunity to spend time with other podcasters, but the highlight of the weekend was our late night performances of Dr. Horrible’s Sing-Along Blog. I had a non-singing part in Act 3 (as the mayor).

Brain Science Podcast #37: Brain Rules with John Medina

Episode 37 of the Brain Science Podcast an interview with Dr. John Medina, author of Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School. We talk about how exercise, sleep, and stress effect our brains with an emphasis on practical advice for healthier brain function. We also look at how research on memory, vision and the brain's attention system suggests how we can improve our ability to learn and our ability to share ideas with others.

Dr. Medina's focus is on considering real world examples of how our schools and work environments could be reformed to utilize the growing knowledge of neuroscience. But he also stresses the importance of compiling sufficient experimental data before embarking on new programs.

Brain Science Podcast #32: Illustrations and Enhanced Podcast

Episode 32 of the Brain Science Podcast was a whirlwind tour of brain anatomy based on Beyond the Zonules of Zinn: A Fantastic Journey Through Your Brain (2008) by David Bainbridge. The author has graciously share the illustrations from his book and I have posted a special page that is keyed to the podcast. I have also created an enhanced version (AAC) version of the podcast, which will not appear in the feed. I think the images are best viewed on the web, but I would appreciate your feedback on both the website illustrations and the enhanced podcast.

See the illustrations on the Brain Science Podcast website.

Brain Science Podcast #32: A Whirlwind Tour of the Brain

Episode 32 of the Brain Science Podcast is a whirlwind (55 minute) tour of brain anatomy. It is based on David Bainbridge's new book: Beyond the Zonules of Zinn: A Fantastic Journey Through Your Brain (2008). Within the next few days I will be expanding the show notes to include key illustrations from the book. I want to thank David for sharing these images and I encourage everyone to read the book.

Brain Science Podcast #29: Author Maryanne Wolf talks about reading and the brain

Dr. Maryanne Wolf, Director of The Center for Reading and Language Research at Tufts University

Brain Science Podcast #29 is an interview with cognitive neuroscientist, Dr. Maryanne Wolf, author of Proust and the Squid: The Story and Science of the Reading Brain. I discussed her book in Episode 24, so this interview was an opportunity to ask her some follow-up questions, and to focus more on how children learn to read. Dr. Wolf shares her ten years of experience helping children learn to read and developing programs to help children with problems like dyslexia. She shares some practical advice for parents as well as her concerns about how reliance on the internet could influence reading skills.

I enjoyed the conversation and, while I especially want to share this episode with parents, I think Dr. Wolf gives everyone some interesting ideas to consider. Listen to the interview.

Books and Ideas #16: Steven Novella from the Skeptics Guide to the Universe

Episode 16 of Books and Ideas is a conversation with Dr. Steven Novella from the popular podcast The Skeptics Guide to the Universe. This interview is a response to numerous requests from fans of the Brain Science Podcast, but I put it in the Books and Ideas feed so that Dr. Novella could share some of his personal experiences both as a physician and as a podcaster.

Show Notes:

Dr. Novella talked a little bit about why he became a physician and about choosing neurology as his specialty. We talked about the role of imaging and how recent advances in neuroscience are influencing patient care. We also talked about the importance of helping patients get accurate information, both from the internet and from their physicians, and how the pressure for physicians to see large numbers of patients hinders good communication. Dr. Novella is committed to evidence-based medicine and we talked about the role of skepticism in evaluating medical claims, both from mainstream and alternative sources. Dr. Novella also talked briefly about his podcast and his blogs, including a new blog specifically devoted to promoting evidence-based medicine.

In the last section of this episode I looked back on the first 15 episodes of Books and Ideas. I particularly want to thank Matthew Cobb for being my first guest back in episode 7. You can get his book Generation at the Books and Ideas aStore at Amazon.com.

Show Notes

This episode is an introduction to the role of the pre-frontal lobes in decision-making, and the other "executive" functions of our brain. The functions of the pre-frontal lobes are not only the keys to what makes us human, but also the keys to our individual personality.

In this episode, using Dr. Goldberg's book, we discuss how the frontal lobes relate to the other structures of the brain. We also, discuss some ideas about why the left and right sides of the brain differ, as well as several important ways in which the cortex, and especially the pre-frontal lobes differ from some of the older parts of the brain.

We discuss briefly the vulnerability of the frontal lobes to damage and disease, and we consider the implications of frontal lobe dysfunction. Questions are introduced that will be considered in more detail in future podcasts.
