Brain Science 136 is a 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. We explore some recent discoveries from reading science and ponder why there is such a large gap between these scientific discoveries and current educational practices in the US.Read More
Olaf Sporns, PhD
Networks 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 amounts of data being generated by current techniques, such as brain imaging. It is also a valuable tool for 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.

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 38 of the Brain Science Podcast is an interview with Jeff Hawkins, author of On Intelligence. Hawkins is well-known for founding Palm Computing and Handspring. He invented the Grafitti handwriting recognition system and helped develop the Palm Trio SmartPhone. Since he published his bestseller On Intelligence, he has devoted his work to his passion for neuroscience. His current company, Numenta, is developing software that models the hierarchical structure of the neocortex. In this interview we talk about the ideas in Hawkins book and how he is applying them to develop a computer model of cortical function. This is a follow-up to Episode 2, which first aired in December of 2006.

It has been a while since I read Edelman's book. Edelman won the Nobel Prize in 1972 for important discoveries about the structure of antibodies, but he has devoted the last several decades to studying neuroscience. His two most well-known contributions are his theory of so-called 'neural Darwinism,' and his study of the importance of redundancy and feedback loops within the brain. He has written quite a few books on the subject including, Wider Than the Sky: The Phenomenal Gift of Consciousness (2005).
Second Nature is Edelman's attempt to address some of the philosophical issues about consciousness, while Wider than the Sky introduces some of his theories about how the brain generates consciousness.
This is a point I have emphasized repeatedly. Inman observes that approaches liked embodied artificial intelligence (which we discussed with Rolf Pfeifer in Episode 25) are really based on a different philosophy of mind that "good old-fashioned AI."
His paper, Philosophy of Mind Using a Screwdriver, is available as a PDF.
Brain Science Podcast #22 is an interview with Dr. Christof Koch of Cal Tech, one of the pioneers in the neurobiological study of consciousness. About two decades ago, when Koch and Francis Crick began looking for what they called the neural correlates of consciousness (NCC), such a quest was considered controversial; but now the field is increasing in popularity. In our interview, we talked a little about his book,The Quest for Consciousness, as well as his on-going research and his thoughts about what the future might bring.
How to get this episode:
Here is a list of some of the topics we discussed:
- Why Francis Crick was an outstanding mentor and colleague.
- A Working definition of consciousness.
- How consciousness relates to awareness.
- What are neural correlates of consciousness.
- Why vision is the focus of Koch's research.
- The search for the "footprints" of consciousness.
- The role of functional imaging and the use of monkeys.
- Neurons-"the atoms of perception".
- Why we need a theory of consciousness.
- The role of the frontal lobes in consciousness.
- Is consciousness an emergent property?
- What about zombies?
- Why do we need consciousness?
- Will artificial intelligence become conscious?
- The hard problem: how does the brain generate subjective experience (qualia).
