Open-minded Conversations

on some new ideas about the scientific study of consciousness & the brain

Science is not done by isolated individuals working alone but rather by an “invisible college,” a dynamic network of individuals and groups.

Because separate empirical research efforts are adding their own findings every month and year, the body of evidence is also expanding – and we are here to broadcast these exciting empirical findings in our podcast.

A Special Tribute

To Nobel Laureate Gerald M. Edelman

Many philosophers think there’s a gap between the mind and body, but there’s no evidence for that.

Nobelist Gerald Edelman pursued a life in science and art, with his family, and with the larger world, in his books, public talks, scientific contributions, and celebration of music. In tribute, our podcast is recorded at the Athenaeum Music & Arts Library, and in Dr. Edelman’s home and library in La Jolla, CA, and co-hosted by his son, neuroscientist David Edelman.

ABOUT THE PODCAST

Jay Giedd is the Director of Child & Adolescent Psychiatry, Rady Children’s Hospital, and Professor of Psychiatry at the UCSD School of Medicine.

Chair of child psychiatry at Rady Children’s Hospital-San Diego and director of child and adolescent psychiatry, Dr. Giedd is also a professor of psychiatry at UCSD School of Medicine. He is a professor in the Dept of Population, Family and Reproductive Health at Johns Hopkins Bloomberg School of Public Health. Dr. Giedd was chief of the Section on Brain Imaging, Child Psychiatry Branch of the National Institute of Mental Health (NIMH).

His widely published research and expertise evaluates how the child’s brain develops in health and illness, the factors that influence development and how to optimize treatments to take advantage of the child’s changing brain. Jay and his award winning work were featured in the PBS 2 part series “Brains on Trial” hosted by Alan Alda.

 

A computational neuroscientist and roboticist, Jeff Krichmar is currently a professor in the Department of Cognitive Sciences and the Department of Computer Science at University of California, Irvine. A Senior Fellow in Theoretical Neurobiology at The Neurosciences Institute from ’99 – ’07, he worked closely with Dr. Gerald M. Edelman. Jeff’s research interests include neurorobotics, embodied cognition, biologically plausible models of learning and memory, neuromorphic applications and tools, and the effect of neural architecture on neural function.

David Edelman, PhD: A neuroscientist and currently Visiting Scholar in the Department of Psychological and Brain Sciences at Dartmouth College, David has taught neuroscience at the University of San Diego and UCSD. He was Professor of Neuroscience at Bennington College until 2014 and visiting professor in the Department of Psychology, CUNY Brooklyn College from 2015-2017.

He has conducted research in a wide range of areas, including mechanisms of gene regulation, the relationship between mitochondrial transport and brain activity, and visual perception in the octopus. A longstanding interest in the neural basis of consciousness led him to consider the importance—and challenge—of disseminating a more global view of brain function to a broad audience.

How do biological systems confront, adapt, and survive in an ever-changing world?

This is the central question that defined Charles Darwin’s scientific journey.

160 years after On the Origin of Species, Natural Selection provides a framework for understanding adaptation at many different scales of biological organization, from protein translation (e.g., ribosomes acting as mRNA message ‘filters’ which determine final protein products), to the immune response (i.e., ‘recognition’ of foreign agents or pathogens by antibodies), to organismal development (e.g., morphogenesis; embryogenesis, etc.), to the origin of species and dynamics of vast ecologies (e.g., rainforest canopies, grasslands, island biogeography, etc.).

Could the very same Darwinian principles help explain how complex nervous systems adapt? It seems like a strange thought.

But more than 40 years ago Gerald Edelman proposed Neural Darwinism, the Theory of Neuronal Group Selection (TNGS), to account for the development and function of the human brain. Neural Darwinism proposes that the functional circuitry of the brain is determined by selective forces operating during development and throughout the life of an organism. It provides a robust biological framework for understanding brain function, including consciousness–the most complex and mysterious of all brain processes.

In a nearly six decade long career, Gerald M. Edelman’s research spanned diverse areas of biological science, including immunology, developmental biology, and neuroscience. The common thread running through all of Dr. Edelman’s pursuits was an enduring interest in the relationship between biology and human experience. Neural Darwinism represents the culmination of his efforts to reconcile the two.

Similarly,  psychobiologist Bernard Baars has sought to link fundamental brain processes and conscious human experience. His Global Workspace Theory and Edelman’s Neural Darwinism naturally complement one another. Both theories propose that the conscious brain supports numerous unconscious processes which together yield a single, coherent stream of experiences.

Through recent neuroscientific advances, we have begun to lift the veil of mystery surrounding consciousness. In an open-minded discussion, the panel explores Neural Darwinism and Global Workspace in the context of these advances and make the case that together, these complementary theories provide a rich biological roadmap of subjective experience.

Through recent neuroscientific advances, we have begun to lift the veil of mystery surrounding consciousness. Through lively discussion, the panel will explore Neural Darwinism and Global Workspace in the context of these advances and make the case that together, these complementary theories provide a rich biological roadmap of subjective experience.

Here, we unpack the Theory of Neuronal Group Selection (TNGS) and make the case that this theory lays out tractable biological ‘first principles’ for building a brain that learns, remembers, and experiences.
