Where is it? Can it be measured? Replicated? Created? Marcus du Sautoy puzzles the problem of consciousness.

Brain imagining techniques have shown that our minds work differently when we're asleep compared to when we're awake, conscious vs. unconscious. Integrated information theory attempts to measure how conscious a system is using mathematical formulae. Could maths answer the question about what consciousness is or do we need to look to philosophy?

This animation was produced by Diana Gradinaru, our 2018-19 animator-in-residence, supported by the Sfumato Foundation and was inspired by Marcus du Sautoy's book "What We Cannot Know".
