Researchers at Ohio State University (OSU) examined the effects of concussions on “sub-cellular levels,” possibly pointing the way for new treatments to be developed for concussions.
According to Science Daily, the OSU researchers discovered that blows to the head cause numerous small swellings along the length of neuronal axons. The study, published in The Journal of Cell Biology, observes the swelling process in live cultured neurons and could lead to new ways of limiting the symptoms associated with concussive brain injuries.
The researchers induced “mild traumatic brain injury” (mTBI) on rodents and found that part of a nerve cell swells within a matter of seconds, much faster than previously believed. The injury activated a protein that caused a chain reaction. Suppressing the protein prevented swelling. Such a finding is highly relevant to mild traumatic brain injury (mTBI), or concussion as it is more commonly known, researcher Chen Gu reports.
