Scientists have long thought that the adult brain is unchangeable, but new evidence is emerging to challenge this belief by revealing that the brain is capable of lifelong change and adaptation.

This adaptability – or neuroplasticity as it is commonly known – shows the mature brain can reorganise or ‘rewire’ itself in response to experience, disease or injury. Associate Professor Michael Valenzuela, Head of the Regenerative Neuroscience Group at the Brain and Mind Centre at the University of Sydney, explains this further.
