About This Course
Global Workspace Theory (GWT) is a leading conceptual framework for the role of conscious and unconscious events in the functioning of the brain, as I first suggested in 1983.
It seems timely to teach courses and seminars on the origins and evidence of the brain’s global workspace. They cover forty years during which consciousness re-emerged from decades of neglect. New evidence and theories are still coming in, but our fundamental understanding is as solid as ever.
In traditional scientific fashion, our basic evidence remains stable while ideas continue to evolve, which we will explore together in rich detail.

Completing this course will help you:
- to understand psychological and brain theories about consciousness.
- learn some of the brain regions associated with conscious, voluntary and unconscious events in the brain.
- learn about the many misunderstandings that are in the popular media outside the sciences.
- understand some of the brain methods used to study conscious and unconscious functions.
- understand how both the inner mental life of human beings and the outside perspective are vital for the whole story.
- understand the difference between computerized simulations of the mind and brain, and the biological basis of consciousness.
Who is the course for?
This course is for you if you are interested in, or teach, or study any of the following subjects: Cognitive or Clinical Psychology, Cognitive Neuroscience, Contemplative Sciences, the Information Sciences, Neuroscience and Education, Health Education, or Philosophy.
Learning Path
In this cognitive neuroscience course, you will be introduced to many fundamental brain regions and their functions.
Along with the historical origins and current evidence supporting GWT, you will learn about
- basic neurobiology,
- sensory pathways,
- connectivity and neural signaling,
- and the conscious and unconscious workings of the mind and brain.
The course includes media-rich lectures & discussion videos, assigned reading, enrichment activities, and quizzes to help you expand your knowledge of the scientific study of mind and brain. By the end of this course, you will have an advanced understanding of conscious cognition and its many roles in the brain.

Modern science started in the Renaissance, when pioneers like Galileo founded the science of physics. Defining consciousness scientifically is similar to Galileo’s efforts to define gravity and heat. (Science fans should keep in mind that physics is still working on understanding gravity.)
In Chapter 1, we examine the question: How do we build on the basic observations about consciousness?

Global Workspace Theory (GWT) started in the 1980s as a purely psychological theory of conscious cognition, and has become a leading approach in scientific studies of consciousness (Mashour et al., 2020).
In Chapter 2, The Conscious Brain: Global Workspace Theory, we explore the origins of GWT.

Many people misunderstand Global Workspace Theory (GWT) to predict a single anatomical center in the brain for the global workspace of consciousness. However, visual consciousness does not emerge in the brain in the same place as auditory consciousness. The different kinds of consciousness, therefore, require different neural bases.
The global workspace of consciousness is proposed to be dynamic and adaptable. We examine this point in detail in Chapter 5.
A global workspace integrates multiple sources of information into a single, unified gestalt, and then spreads that summarized information to the rest of the brain.

When scientists returned to the conscious brain, medical applications started to appear quickly. After almost a century of neglect we are seeing a significant scientific renaissance. Global Workspace Theory (GWT) continues to help clarify a wave of new evidence and theory.
Conscious cognition is not some vague side effect of the physical brain, as many skeptics have claimed. Rather, the conscious brain is essential for Darwinian fitness.
Here we explore groundbreaking examples in medical science.

“Bernard Baars is the William James of consciousness studies in the 21st century.
Taking into account recent developments of computer and cognitive sciences, neuroscience, psychology, and linguistics ⎯ the empirical basis of Baars' work is the best one can get.”
“On Consciousness: Science and Subjectivity highlights Baars’ strongly scientific approach combined with his brilliant creativity as he forges new ways of thinking about ancient questions ⎯ a stunning achievement!.”
“Bernie Baars is the leading thinker behind the Global Workspace theory of consciousness that has been recently championed by top neuroscientists, such as Stanislas Dehaene.”
“Bernard Baars is both one of the pioneers of the cognitive study of consciousness and currently one of its most important contributors.”
