A multiscale computational approach to estimating axonal damage under inertial loading of the head.
TL;DR: A conceptual framework is demonstrated to estimate the degree of axonal injury in the fiber tracts of the human brain, enabling the future development of relationships between computational simulation and neurocognitive impairment.

Rotational Acceleration, Brain Tissue Strain, and the Relationship to Concussion
Andrew Post,T. Blaine Hoshizaki +1 more
TL;DR: The links between research conducted in different disciplines are presented to better understand the relationship between linear and rotational acceleration and brain strains that have been postulated as the root cause of concussion.

Finite element analysis of the effect of loading curve shape on brain injury predictors.
TL;DR: UCDBTM is used to analyse three distinct loading curve shapes meant to represent different helmet loading scenarios and results indicate that loading curve A produced consistently higher maximum principal strains and Von Mises stress than the other two loading curve types.

Traumatic brain injuries: the influence of the direction of impact
Andrew Post,Thomas Blaine Hoshizaki,Michael D. Gilchrist,Michael D. Gilchrist,Susan Brien,Michael D. Cusimano,Shawn Marshall +6 more
TL;DR: There is an effect that impact direction has on TBI depending on the anatomy involved for each particular lesion, and there is a continuum of stresses and strain magnitudes between lesion types when impact location is isolated.
Characterization of persistent concussive syndrome using injury reconstruction and finite element modelling.
Andrew Post,Marshall Kendall,David Koncan,Janie Cournoyer,T. Blaine Hoshizaki,Michael D. Gilchrist,Michael D. Gilchrist,Susan Brien,Michael D. Cusimano,Shawn Marshall +9 more
TL;DR: Brain tissue stresses and strains that occur in impacts that led to persistent post concussive symptoms (PCS) in hospitalized patients support the theory that there exists a progressive continuum of impacts that lead to agressive continuum of related severity of injury from transient symptoms to pathological damage.
