Professor Brian Cox and an expert panel explore the elusive science of consciousness – what it is, how it arises, whether it can be observed in the brain, and the most compelling theories explaining it. 

In a deep, often mind-bending discussion, the panel tackles the many ways of interpreting consciousness itself, and how fields like psychophysics can be used to quantify imagination and perception.    

With questions from the audience, the conversation delves into hallucinations and reality, how memory helps to build identity, and whether AI could ever be conscious too.
