High-speed and high-resolution videography techniques have enabled studies of physical models of the brain that undergo large deformations at high strain rates. The skull of a miniature pig was filled with two layers of silicone gel; a grid pattern was painted between the layers. The assembly was subjected to angular accelerations of 50,000–200,000 rad s⁻² while grid deformation was recorded at 1,000 frames per second. Adapted from Reference 42.
