We are honored to host Dr. Stuart Hameroff at the Brain Institute on March 2nd, 2023.

Dr. Hameroff gave a talk titled “Is the brain a computer, or a quantum orchestra? A new paradigm needed in neuroscience “.

Abstract:

Neuroscience views the brain as a complex computer of simple neurons, a paradigm unable to account for consciousness, memory nor free will, and an insult to neurons.
Single-cell organisms with no synapses perform purposeful intelligent functions using their cytoskeletal microtubules. Brain neurons are filled with microtubules, selfassembling cylindrical protein polymers which organize synapses, encode memory and process information. Microtubules collectively resonate in scale-invariant, fractal-like patterns in hertz, kilohertz, megahertz, gigahertz and terahertz frequency ranges. At the higher frequencies, quantum vibrations and state reductions can entangle and interfere across frequencies, like musical notes and chords resonating across scales. Quantum coherence provides cognitive binding, real-time causal action (by Penrose OR state reduction, enabling free will through retroactivity), and can potentially solve the ‘hard problem’. In Penrose OR, basic ‘qualia’ of conscious experience are events in the fundamental makeup of the universe, spacetime geometry. Penrose-Hameroff ‘Orch OR’ suggests microtubules in brain neurons ‘orchestrate’ qualia into full rich conscious experience. Evidence shows quantum processes in microtubules are inhibited by anesthetics which selectively block consciousness. And megahertz and gigahertz coherent oscillations can now be detected from the scalp within the EEG (Anirban Bandyopadhyay group). Neuroscience needs a new paradigm. The brain should be viewed as a scale-invariant hierarchy extending from neurons both upward to larger networks, but also downward, inward, to deeper, faster ‘scale-invariant’ quantum processes in cytoskeletal microtubules inside neurons, and ultimately to fundamental spacetime geometry. Rather than a classical computer, the brain is like a quantum orchestra. Rather than computation, consciousness is like music in the fine scale geometry of the universe.

My research focuses on consciousness and free will. I am interested in whether we are conscious of what goes on in our own minds and whether we have free will. I am also interested in our beliefs about consciousness and free will and how these beliefs affect our behavior. My main current project investigates what goes on in our brains and what we are conscious of when we perform a spontaneous voluntary action, specifically: whether we are conscious of mental imagery related to the action and whether the generation of such mental imagery is reflected in a brain signal, the readiness potential, that is associated with spontaneous voluntary actions.

 I graduated from the master in cognitive sciences at the University of Lyon Lumière 2 (France) in 2021. Then, I had the opportunity to work as a research assistant during 8 months at the Université Libre de Bruxelles with Prof. Emilie CASPAR (M&SB lab). We conducted projects investigating several processes related to decision-making, such as the sense of agency, empathy for pain and cognitive conflict using EEG. We approached rare populations such as inmates, military, and former perpetrators and survivors of the genocide in Rwanda. In 2022, I had the honor to receive a 6-month predoctoral fellowship offered by the Neurophilosophy of Free Will for the project ‘Does the Readiness Potential reflect action initiation or uncertainty?’.

I am now a PhD student under the supervision of Pr. Axel CLEEREMANS (CO3) and Pr. Uri MAOZ (Brain Institute). My research focuses on the neural markers of volition, with a specific interest in the Readiness Potential. In a broader sense, my topic of interest is to investigate how to model decision-making and how these findings can feed the debate on free-will.

My research focuses on consciousness, its neural correlates and its functions: how does it come about, and what – if anything – does it do. As part of this interdisciplinary collaboration, we will focus on volition, and study the possible role consciousness might play in volitional actions. We will further ask if this role changes as a function of decision type, differentiating between arbitrary decisions and deliberate, meaningful ones. To do so, we will use different imaging techniques as well as psychophysical methods.

Michael I. Posner - Enhancing Brain Networks of Conscious Control

On May 3rd, 2019, the Brain Institute hosted Dr. Michael Posner for a lecture with a topic of “Enhancing Brain Networks of Conscious Control“. This lecture is sponsored by The Federico & Elvia Faggin Foundation and is the inaugural lecture of this Faggin Lectures Series.

Michael I. Posner is an American psychologist, the editor of numerous cognitive and neuroscience compilations, and an eminent researcher in the field of attention. He is currently an emeritus professor of psychology at the University of Oregon, and an adjunct professor at the Weill Medical College in New York.

ABSTRACT

The problem of consciousness can be divided into awareness and control. This lecture concentrates on the mechanisms of control. Control of behavior is exercised through a brain network involving the anterior cingulate, anterior insula and underlying striatum. The efficiency of this network can be examined through the ability to resolve conflict among competing responses. This network develops in early childhood and comes to control our voluntary responses. Pathways through which this mechanism operates can be improved by experience, for example, by 2-4 weeks of meditation training. Meditation training enhances intrinsic frontal theta. We have shown in mice, inducing frontal theta with optogenetics enhances white matter connectivity. We are testing the possibility that enhancing intrinsic theta may improve white matter anywhere in the human brain. If this is possible we may be able to help people with disorders that involve reduced connectivity. By dividing the study of consciousness into more elementary issues considerable progress has and can be made.

The newly-minted Institute for Interdisciplinary Brain and Behavioral Science (The Brain Institute) at Chapman University, with Dr. Uri Maoz as project leader, is the recipient of a total of $7.04 million to study how the human brain enables conscious control of decisions and actions. The John Templeton Foundation funded $5.34 million; the Fetzer Institute funded $1.55 million; and the remaining $150,000 comes from the Fetzer Memorial Trust. This is Chapman’s largest non-federal research grant to date. With the Chapman Brain Institute serving as the central hub, this grant supports research efforts at 17 universities spanning four continents: including Charité Berlin (Germany), Dartmouth, Duke, Florida State University, Harvard, Indiana University Bloomington, NIH, Monash University (Australia), NYU, Sigtuna (Sweden), Tel Aviv University (Israel), University College London (UK), University of Edinburgh (UK), UCLA, and Yale.

The project will launch at an international conference on the Neuroscience of Free Will that the Brain Institute and Crean College of Health and Behavioral Sciences at Chapman University will host March 14-18. A celebratory Grand Opening Dedication and Ribbon Cutting is scheduled for 10:30 a.m. Wednesday, March 13, at the Harry and Diane Rinker Health Science campus, located at 14725 Alton Parkway, Irvine. The event and light brunch to follow is open to the entire campus community.

“We were pleased to establish Chapman’s Brain Institute and to bring the faculty associated with it to Chapman University last year,” said Daniele Struppa, Ph.D., Chapman University president. “Their approach to research reflects Chapman’s goal of combining research with teaching and involving undergraduate and graduate students at all levels in the process. We are grateful for this grant from the Templeton Foundation and the Fetzer Institute, which recognizes Chapman as a leader in this developing field.”

“This grant aims to create a new field in the study of the brain—the neurophilosophy of free will,” said Uri Maoz, Ph.D., assistant professor of psychology and computational neuroscience at Chapman University. “The extent and scope of human free will have been debated by philosophers for millennia. In recent decades, neuroscientists have joined the discussion, leading to some interesting discoveries. The current project, however, represents a four-year effort forging structured, close collaborations on these questions between eight neuroscientists (including Dr. Aaron Schurger, assistant professor of psychology, the latest faculty recruit to the Brain Institute at Chapman) and nine philosophers from around the world. Hopefully, in 10 years we will look back at the grant and say that’s where it all started,” said Dr. Maoz.

“This large-scale investment, by the John Templeton Foundation and the Fetzer Institute, comes to the Brain Institute even before its official launch next month,” said Amir Raz, Ph.D., Chapman University professor of psychology and brain sciences and director of the Brain Institute. “Work at the Brain Institute addresses fundamental questions of human experience: do we have free will? Are we, in fact, free to do what we wish? What is the role of consciousness in our decisions? We are grateful for the opportunities the combined grant offers as well as the testament it provides to confidence in our work.”

“The Templeton Foundation and Fetzer Institute grant acknowledge that consequential, complex questions find answers only when approached through the lenses of multiple disciplines and their research techniques,” said Janeen Hill, Ph.D., dean of Crean College. “Chapman University’s and Crean College’s commitment to brain science and its inherent interdisciplinarity is reinforced by the significance of this combined grant.”

Entitled “Consciousness and Free Will: A Joint Neuroscientific-Philosophical Investigation,” the grant aims to advance efforts in the neurophilosophy of free will. For example, researchers at the Brain Institute and their collaborators will use advanced analysis techniques of brain activity and strive to decode decisions and actions before they take place. Or they will use various techniques to compare human brain activity when people make arbitrary decisions (e.g., when asked to randomly raise their left or right hand) and deliberate ones (e.g., when asked to raise their left or right hand to donate to one charity or another).

“This grant, placing Chapman as a leader in neuroscience, reflects our deepening commitment to research and to academic excellence,” said Glenn Pfeiffer, Ph.D., provost of Chapman University. “This announcement comes soon after the recent elevation of Chapman University to Carnegie Classification R2, signifying ‘high research activity.’ We have never been stronger as a research institution than we are right now.”

“In fact,” said Thomas Piechota, Ph.D., PE, vice president of research, “this is an opportune time to partner with Chapman University. The research being conducted by the Brain Institute and throughout Chapman is exciting and innovative. Our faculty are exemplary researchers and the involvement of students of every level – including first-year undergraduates – is a fundamental part of the personalized education that we offer.”

Hosted at the Rinker Health Science campus in Irvine, as well as on the Orange campus, the Brain Institute comprises a network of interdisciplinary researchers who conduct empirical investigations into the cognitive neuroscience of altered planes of consciousness, neuropsychology, volition, formal models of higher brain functions among other fields. Our work draws on clinical populations, healthy volunteers, and innovations in artificial intelligence, machine learning, and big data.

“Questions about consciousness and free will are of enduring interest in both philosophy and the sciences. This project will feature field-leading researchers on these two topics, using rigorous and collaborative methods to advance our understanding of both of them. It is, therefore, a perfect fit for the John Templeton Foundation, and we are pleased to support Chapman in this initiative,” said John Churchill, director of philosophy and theology programs at the John Templeton Foundation.

“We are drawn to this work because of its cutting-edge exploration of free will, the breadth of the research effort Chapman University has developed, and the scale of this major funding collaboration with Templeton,” said Mohammed Mohammed, Fetzer Institute program director of research, discovery, and development. “We are excited about this venture into the intersection of philosophy and neuroscience.”

Dr. Buccella received her PhD in philosophy from the University of Pittsburgh in 2020. At the core of her work lies the relationship between so-called ‘subjective’ and ‘objective’ aspects of experience. On the one hand, experience discloses the world to us, making its objective features available for knowledge and action. On the other hand, experience is irreducibly subjective and perspectival. In her research, Dr. Buccella explores the co-dependent notions of objectivity and perspective in different contexts, at the interface between philosophy, psychology, and neuroscience. More specific topics include perceptual constancy, the role of mental representations in cognitive science, feminist themes in enactive-embodied theories of cognition, and the philosophical foundations of machine learning.
