Michael Graziano explains Peripersonal Neurons (BS 142)
Michael Graziano (Click image to play audio) As a young student Dr. Michael Graziano helped discover peripersonal neurons, which are neurons that detect when objects are coming near our bodies. In his new book The Spaces Between Us: A Story of Neuroscience, Evolution, and Human Nature, Graziano takes us through two decades of research into how these neurons work. Peripersonal neurons make it possible for us to move through our lives without constantly bumping into the objects and people around us, but because they work outside our conscious awareness we take them for granted. Graziano &nbs...

Rodrigo Quian Quiroga: Memory and Perception (BS 141)
Rodrigo Quian Quiroga (Right click to listen) Neuroscientist Rodrigo Quian Quiroga has written a wonderfully accessible book called The Forgetting Machine: Memory, Perception, and the "Jennifer Aniston Neuron. " I interviewed him for BS 141 because I wanted to hear the real science behind his work. The key idea of his book his that perception and memory are based on similar principles. Our perceptions are largely created by our brains, but the same is also true for our memories.Our memories are dynamically recreated with each recall. This has important and surprising implications. We also ...

Jeff Hawkins Explores a New Theory of Cortical Function (BS 139)
Jeff Hawkins (Click to play interview) My Brain Science podcast was partially inspired by Jeff Hawkins bestseller On Intelligence, so I am very pleased to post a new interview (BS 139) in which we discuss the exciting work he has been doing at Numenta. Hawkins is committed to understanding how the neocortex generates intelligence and he feels that his latest paper marks an important landmark in that work.We started our conversation by discussing some of the work that Hawkins published in 2016 including two key papers. One presents a new model of the neuron that incorporates active dendrite...

John Medina on Aging Well (BS 138)
Dr. John Medina has spent his career in bio-engineering, but he also has a deep interest in how the brain works. In his latest bookBrain Rules for Aging Well: 10 Principles for Staying Vital, Happy, and Sharp, he presents our knowledge brain aging in an engaging manner that can be enjoyed by readers of all backgrounds.In this month's episode of Brain Science (BS 138) we discuss some of the most important principles for nourishing brains as we age. He describes what he calls the "dopamine lollipop," which is the surge of dopamine created by activities such as teaching and physical activities like dancing. Some of his ideas ...

Seth Grant's latest Research (BS 137)
Seth Grant has made a career by combining his skills in molecular biology, medicine and neuroscience. Brain Science listeners may remember him best for his explorations of the evolution of the synapse (BSP 51) and in BSP 101 he told us about how small genetic changes related to synapse proteins can influence learning, but this month he shares a new paper, which describes what he calls the "genetic lifespan calendar.” The key idea is that the genes in both the mouse and human brain appear to follow a predictable schedule. Grant’s team also found that they could predict the age of a brain by looking at its transcrip...

Why Reading Science Matters (BS 136)
Click to listen to podcast The latest episode of Brain Science (BS 136) is discussion of Language at the Speed of Sight: How We Read, Why So Many Can’t, and What Can Be Done About It by Mark Seidenberg . Unfortunately I was unable to reach the author, so this is a return the show's early days when it was not dominated by interviews. This book contains information that is important to anyone who cares about how children learn to read. One key theme is that there is a large gap between current reading science and educational practice.In this podcast we explore the relati...

Lisa Barrett on How Emotions are Made (BS 135)
Lisa Felman Barrett (click to play interview) In How Emotions are Made, neuroscientist Lisa Feldman Barrett challenges a key long-standing assumption about emotions. She argues persuasively that the evidence does not support the idea that emotions are universal and hardwired. She calls this the classical theory because versions of this idea have been around at least since the ancient Greeks, but the idea was also one that Darwin embraced. It is also embedded in several past episodes of this podcast, including the popular interviews with Jaak Panksepp.In the Brain Science 135 I spoke with D...

Remembering Jaak Panksepp (BS 134)
Neuroscientist Jaak Panksepp spent much of his career toiling in relative obscurity, but when he died in April 2017 the Washington Post credited him with "revealing the emotional lives of animals." His book Affective Neuroscience essentially created a new field and he was a very popular guest on the Brain Science Podcast .This month I want to honor Dr. Panksepp by re-airing the first interview I recorded with him back in 2010. While newer theories about emotion disagree with Dr. Panksepp's conclusion that all mammals, including humans, share basic subcortical circuits that cause emotions, his appreciation for the affect...

Counting Neurons with Dr. Suzana Herculano-Houzel (BS 133)
Suzana Herculano-Houzel (photo by Joe Howell/Vanderbilt U) Click to Play Dr. Suzana Herculano-Houzel and her colleagues developed a pioneering technique that has made it possible to accurately count the number of neurons in brains of all sizes. This has led to some big surprises including the fact that the human brain contains an average of 86 billion neurons rather than 100 billion as had long been assumed. She describes this work in her wonderful book The Human Advantage: How Our Brains Became Remarkable and I really enjoyed interviewing her for Brain Science 133. While some neu...

Honoring William Uttal's Contributions to Cognitive Neuroscience (BS 132)
William Uttal 1931-2017 (click to play)Dr. William Uttal, who died last month at the age of 86, had a very unusual career, going from physics and engineering to psychology and cognitive science. I think his unique background contributed to the refreshing skepticism that he brought to the growing use of imaging (especially fMRI) in the cognitive sciences.He was a prolific writer on the subject and back in 2012 I had the honor of talking with him about his bookMind and Brain: A Critical Appraisal of Cognitive Neuroscience. In addition to shedding light on the limitations of imaging (such as poor reproducibility), Dr. Uttal a...
