Figure 4.

The onset and the extent of selected pathological mechanisms of bTBI by injury severity. Hypothetical model. The colored horizontal bars intend to illustrate the approximate onset and extent of the individual pathological changes following injury. The color intensities and bold type reflect an increased severity and contribution of the individual pathologies, whereas lighter colors, question marks, and strikethroughs represent weaker, relatively transient, or nearly absent conditions. Abbreviations: hr, hour(s); wk., week(s); mo., month(s).
