Despite its quiet appearance, the brain is the seat of complicated wave dynamics. Indeed, cognitive processes are carried out through communications between neurons, leading to synchronisation and oscillations at different frequencies that can be recorded. Together, these oscillations also create waves that propagate through different regions. Apart from this electrical activity, the brain is also the siege of slow chemical waves that can cause migraine and mechanical waves arising from trauma. In this lecture, we will study the influence of all these waves on brain function.

This lecture was recorded by Alain Goriely on 18th March 2025 at Barnard's Inn Hall, London.

Alain is Gresham Professor of Geometry.

He is currently the Director of the Oxford Centre for Industrial and Applied Mathematics and was elected as a Fellow of the Royal Society in 2022.
