Explosions can tear apart buildings, send shrapnel flying, and hurtle humans into the air. But explosions also cause damage in ways that aren’t as visually apparent. Scientists say the force of a blast can cause brain damage, but questions linger about how the symptoms that emerge after a blast-induced traumatic brain injury are connected to the initial trauma.
In their quest to learn more about how symptoms emerge after a traumatic blast, researchers at the Ludwig-Maximilians University of Munich, in Munich, Germany have developed an animal model of blast-related mild traumatic brain injury (br-mTBI) using C. elegans – a popular model organism alternative to vertebrate animals.
In their study, published in Frontiers in Behavioral Neuroscience, the research team used WormLab to analyze thousands of worms. They found that shockwaves either slowed the worms’ movements or rendered them paralyzed. Symptoms played out in a dose-dependent manner, meaning that worms exposed to a higher number of shockwaves displayed a higher severity of symptoms.
