Figure 2. Concussive head trauma propagates strain throughout the brain.

Heat map of representative brain shows predicted maximum principal strain at (A) 0.85 ms and (B) 1.64 ms after initial impact. (C) Time history of maximum principal strain within the cortex (blue), thalamus (red), substantia nigra (black), cerebellum (green), and brainstem (magenta).

(A) Measurement for impactor on brain injury device. (B) Finite element model of the impactor, skull, and brain regions with standardized material properties. Finite element model of the mouse brain at (C) 0.85 milliseconds and (D) 1.64 milliseconds post-impact. Heat map provides predicted von Mises stress. (E) Time history of von Mises stress after impact within the cortex (blue), thalamus (red), substantia nigra (black), cerebellum (green), and brainstem (magenta).
