Side Impacts Could Cause Concussion

Hoboken, NJ ( – A new study highlighted by Stevens Institute of Technology shows that location of impact can potentially lead to brain damage or concussions.

Stevens mechanical engineer Mehmet Kurt and graduate student Javid Abderezaei worked with Assistant Professor of Biomedical Engineering Kaveh Laksari of the University of Arizona and Songbai Ji of Worcester Polytechnic Institute to study frequencies in the corpus collosum and periventricular region of the brain. What they found was that these two regions of the brain resonate a higher frequency resulting in more mechanical energy and shear strain. This causes more tissue and cell damage.

According to Kurt, “The brain not only rings, but it has a distinct pattern of ringing when the head is hit from the side and experiences rotational acceleration,”

According to Abderezaei, an impact to the brain causes non-linear movement within the brain. When adding in the factor of tough membranes located in the side regions of the brain, the impact is even greater. “That means that small increases in amplitude can lead to unexpectedly big deformations in certain structures.”

The corpus collosum is the region of the brain that connects the two hemispheres. It is also the largest pathway in the brain. The periventricular region is the white matter on the sides of the brain and is responsible for muscle movement and nerve impulses.

Kurt’s full study is available on Physics Review Applied.
