“The Self-Assembling Brain” and the Quest for Artificial General Intelligence with Professor Peter Robin Hiesinger

How does a network of individual neural cells become a brain? How does a neural network learn, hold information and exhibit intelligence? While neurobiologists study how nature achieves this feat, computer scientists interested in artificial intelligence attempt to achieve it through technology. Are there ideas that researchers in the field of artificial intelligence borrow from their counterparts in the field of neuroscience? Can a better understanding of the development and working of the biological brain lead to the development of improved AI? In his book “The Self-Assembling Brain: How Neural Networks Grow Smarter” professor Peter Robin Hiesinger explores stories of both fields exploring the historical and modern approaches. In this episode of Bridging the Gaps, I speak with professor Peter Robin Hiesinger about the relationship between what we know about the development and working of biological brains and the approaches used to design artificial intelligence systems.

We start our conversation by reviewing the fascinating research that led to the development of neural theory. Professor Hiesigner suggests in the book that to understand what makes a neural network intelligent we must find the answer to the question: is this connectivity or is this learning that makes a neural network intelligent; we look into this argument. We then discuss “the information problem” that how we get information in the brain that makes it intelligent. We also look at the nature vs nurture debate and discuss examples of butterflies that take multigenerational trip, and scout bees that inform the bees in the hive the location and distance of the food. We also discuss the development of the biological brain by GNOME over time. We then shift the focus of discussion to artificial intelligence and explore ideas that the researchers in the field artificial intelligence can borrow from the research in the field of neuroscience. We discuss processes and approaches in the field of computing science such as Cellular Automata, Algorithmic Information Theory and Game of Life and explore their similarities with how GENOME creates the brain over time. This has been an immensely informative discussion.

“Free Will” Through the Lenses of Philosophy and Neuroscience with Dr Alfred Mele

"Surrounding Free Will"

The debate over whether or not free will exists is not new. The main points of contention in this discussion are whether or not we have control over our actions, and if so, what kind of control we have and to what extent. On the one hand, we have a strong sense of liberty, which causes us to trust in our own free will. An intuitive and instinctive sense of free will, on the other hand, could be misinterpreted. In this episode of Bridging the Gaps, I speak with Dr Aflred Mele and we discuss the concept of “Free Will” from the perspective of philosophy and from the perspective of neuroscience.

Dr Alfred Mele is a Professor of Philosophy at Florida State University. His research interests include issues about human behavior located at the intersection of philosophy and science such as free will, personal autonomy, self-deception, self-control, intention, intentional action, motivation, and moral responsibility. He is also the past Director of the Philosophy and Science of Self-Control Project and the Big Questions in Free Will Project.

I open this discussion by asking Dr Mele to unpack the concept of “Free Will”. I then ask Dr Mele to outline important philosophical views about the concept of “Free Will” that emerged over time. We discuss in detail the relevant concepts of determinism, compatibilism, incompatibilism, and libertarianism. We then discuss the concept of Free Will through the lens of neuroscience. We discuss a number of experiments conducted by neuroscientists. The finding of these experiments seems to suggest that that free will is an illusion. But the question is, is it right to extrapolate the findings of these experiments that focus on simple choices and are conducted in controlled environments to conclusively suggest that free will does not exist. Dr Mele discusses this point in detail.

The Spike: Journey of Electric Signals in Brain from Perception to Action with Professor Mark Humphries

Neurons are the fundamental building blocks of the brain. In the human brain, billions of these neurons communicate and liaise with one another using spikes, blips of electric voltages. Studying and understanding how these spikes emerge in the brain, how they travel through the brain and how this communication leads to meaningful actions are part of the cutting edge research in the field of neuroscience. In this episode of Bridging the Gaps I speak with professor Mark Humphries and discuss the research that he presents in his new book “The Spike: An Epic Journey Through The Brain in 2.1 Seconds”. This is a deeply informative account of the journey that these electrical signals take as they move from one neuron to another and eventually lead us to act. The book tackles previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? In this thorough discussion with professor Mark Humphries, we touch upon these fascinating questions and intriguing concepts.

Mark Humphries is Chair in Computational Neuroscience at the University of Nottingham. He is the founding editor of “the Spike” an online publication available at Medium dot com.

I begin our conversation by asking Mark about the structure of an individual neuron and how spikes emerge in a single neuron. We then discuss the concept of Dark Neuron and talk about the spikes that don’t lead to new spikes and just fail. A very interesting question is what do these spikes mean and how do these spikes carry messages from one point in the brain to another. In the book, Mark reports two groups of researchers holding two different viewpoints, these are “The Timers” and “The Counters”. I ask Mark “who are the timers” and “who are the counters” and what are their viewpoints on the question that how these spikes carry messages from one point in the nervous system to another. And finally we discuss how research is conducted in the fields of neuroscience and computational neuroscience. We particularly discuss progress that the researchers are making in the field of computing neuroscience.
