Have you ever wondered how your brain creates the vivid experience of reality that you perceive every day? The scientific study of consciousness aims to unravel this fascinating mystery. It’s not just about understanding how the brain processes sensory signals, but how it constructs our entire conscious experience.

Building the Experience
The brain, enclosed within the protective skull, receives sensory signals from the outside world. Yet, inside the darkness, it conjures up our reality by continuously making predictions about the causes of these signals. It doesn’t just passively read the information; rather, it calibrates and updates its predictions based on the incoming sensory data. This dynamic process creates a convincing and compelling experience of the world around us.
Uncovering the Brain Basis of Consciousness
At the University of Sussex, our research group employs various experimental approaches to shed light on the brain basis of consciousness. For instance, one experiment focuses on the brain’s predictions about sensory signals. We present participants with images of faces and houses, making them expect to see either one. Surprisingly, people perceive what they expect to see more quickly and accurately than the unexpected.
This experiment demonstrates that perception is strongly influenced by our brain’s internal predictions. The famous saying “I’ll believe it when I see it” actually works in reverse – “I’ll see it when I believe it.” Our brain’s predictions shape our conscious experience.
The Hard Problem of Consciousness
For centuries, the nature of consciousness has puzzled thinkers. How can we explain the subjective experience of redness or the sharp pain of jealousy? These questions constitute what philosopher David Chalmers labeled the “hard problem of consciousness.” It seemed impossible to explain such subjective phenomena through physical mechanisms.
However, history has shown that seemingly unexplainable phenomena eventually become explicable. Take the example of understanding life. Not long ago, life appeared mysterious and beyond the realm of physics and chemistry. But today, while we may not know everything, the grand sense of mystery has diminished. Perhaps, by adopting a similar approach, the hard problem of consciousness can also be resolved.
Progress in Understanding Consciousness
Thanks to advancements in brain imaging techniques, we now have a better understanding of consciousness. By examining the living human brain, we can identify neural patterns associated with conscious experiences. For instance, different brain activities are linked to different states of consciousness, such as wakefulness, sleep, anesthesia, and even psychedelic experiences.
We’ve made significant progress by developing measures of brain dynamics, such as brain complexity. This measure quantifies the diversity of activity patterns in the brain, providing a rough approximation of an individual’s level of consciousness. Being able to quantify consciousness is a powerful and valuable tool for researchers.
The Profound Mystery
Consciousness is not just a scientific puzzle; it’s a deeply personal mystery. From childhood, questions about identity and the nature of our own experiences arise. Where were we before birth? What happens after death? Who are we, and what does it all mean? These questions resonate throughout our lives, evoking a sense of wonder and curiosity.
