The human brain is an organ of extreme complexity, the object of ultimate intellectual egocentrism, and a source of endless scientific challenges. Despite a clear evidence that mechanical factors play an important role in regulating brain activity, current research efforts focus mainly on the biochemical or electrophysiological activity of the brain. However, classical concepts from mechanics including deformations, stretch, strain, strain rate, pressure, and stress also play a crucial role in both shaping the brain and modulating its functions. In this talk, I will review our current understanding of the brain and present several important mechanical problems and mathematical models related to brain geometry, proper brain function, and brain pathology and trauma. In particular, I will present simple models for brain oedema formation and propagation, a dangerous consequence of traumatic brain injury.
