“On Task: How Our Brain Gets Things Done” with Professor David Badre

Neural mechanisms in the human brain that are responsible for generating and keeping track of plans, and influencing a cascade of brain states that can link our goals with the correct actions are known as Cognitive Control. These mechanisms and processes enable us to transform plans and goals into actions. Cognitive Control, also known as Executive Control inhibits automatic responses and supports flexible, adaptive responses and enables sophisticated actions to achieve desired goals. From making a cup of coffee to buying a house, from planning a trip to a shopping mall to outlining a career path, humans are uniquely able to execute necessary actions. How do we do it? In his book “On Task: How Our Brain Gets Things Done”, cognitive neuroscientist David Badre presents the first authoritative introduction to the neuroscience of Cognitive Control. In this episode of Bridging the Gaps I speak with Professor David Badre to discuss this astonishing phenomenon, these fascinating mechanisms that have profound impact on our well-being.

David Badre is professor of cognitive, linguistic, and psychological sciences at Brown University, where he is also on the faculty of the Carney Institute for Brain Science. He and his lab have made pioneering contributions to the neuroscience of Cognitive Control and Executive Function.

I open our discussion by asking professor Badre why the scale of Cognitive Control activities is very large in the human brain as compared to all other animals. We discuss the effectiveness of Cognitive Control which is unique to the human brain. These days it is widely accepted that the prefrontal cortex is crucial for our highest mental functions, including cognitive control. But it took us a while to understand this. Professor Bare discusses the research on “the puzzle of the frontal lobe” that informs us that the prefrontal cortex is crucial for our highest mental functions. Cognitive control is about transforming knowledge into actions; so before actions can happen, the knowledge must exist. Professor Badre explains our present understanding of how the brain acquires knowledge through learning and how acquired knowledge is retained in the memory. Professor Badre explains how the brain aims to balance stability and flexibility in general and how it aims to balance cost and reward during the information retrieval process. We also touch upon fascinating research questions that professor Badre and his colleagues are presently working on in BadreLab.

The Evolution of Knowledge and Rethinking Science for The Anthropocene with Professor Jürgen Renn

Most history of science publications narrowly focus on specific periods in human history, or particular disciplines of scientific discovery, or small sets of scientists and philosophers. However there is a view that history of science can be better understood against the background of a history of knowledge including not only theoretical but also intuitive and practical knowledge. This can be further broadened by including cognitive, material and social dimensions of knowledge. Studying how knowledge structures are formed and evolve as knowledge spreads should further enrich our understanding of development and progress of science and technology. In his new book “ The Evolution of Knowledge: Rethinking Science for the Anthropocene” Jürgen Renn presents a new way of thinking about the history of science and technology, one that offers a grand narrative of human history in which knowledge serves as a critical factor of cultural evolution.

Jürgen Renn is a director at the Max Planck Institute for the History of Science in Berlin, where, together with his group, he researches structural changes in systems of knowledge. Jürgen Renn is honorary professor for History of Science at both the Humboldt-Universität and the Freie Universität Berlin. He is currently serving as Chairperson of the Humanities Sciences Section of the Max Planck Society.

In this book Jürgen Renn examines the role of knowledge in global transformations going back to the dawn of civilization while providing vital perspectives on the complex challenges confronting us today in the Anthropocene—this new geological epoch shaped by humankind. He reframes the history of science and technology within a much broader history of knowledge, analyzing key episodes such as the evolution of writing, the emergence of science in the ancient world, the Scientific Revolution of early modernity, the globalization of knowledge, industrialization, and the profound transformations wrought by modern science. He investigates the evolution of knowledge using an array of disciplines and methods, from cognitive science and experimental psychology to earth science and evolutionary biology. The result is an entirely new framework for understanding structural changes in systems of knowledge—and a bold new approach to the history and philosophy of science.

In this episode of Bridging the Gaps, I speak with professor Jürgen Renn, one of today’s preeminent historians of science. We discuss fascinating research that he presents in The Evolution of Knowledge. We discuss the origin, evolution and spread of knowledge, and other insights that Jürgen Renn discusses in this thorough book.

Origin Of Mathematics and Mathematical Thinking with Dr Keith Devlin

Mathematics is everywhere. We use numbers, quantities, values and measurements almost all the time. Counting and quantifying is part of almost everything that we do.

An interesting question is how did it all start. When did humans start thinking mathematically and what is the origin of mathematical thinking. As we start tacking these questions, we stumble upon few more queries: how did our brain evolve to do mathematics; what are fundamental capacities that enable humans to do mathematical thinking; what are major milestones in the evolution of mathematical thinking and in the history of mathematical innovations; is mathematics discovered or is it invented. I invited Dr Keith Devlin to join me in this episode of Bridging the Gaps for a discussion that focuses on these questions.

Dr Keith Devlin is the director of the Stanford Mathematics outreach project at Stanford University. His current research is focused on the use of different media to teach and communicate mathematics to diverse audiences. He has written 33 books and over 80 research articles. He is a World Economic Forum Fellow, a Fellow of the American Association for the Advancement of Science, and a Fellow of the American Mathematical Society.

Complement this with intriguingly informative discussion “Robots, Artificial Life and Technology Imagined by the Ancients” with Adrienne Mayer.
