A blast is a shock wave to travel through the air supersonically. Most people are familiar with it in the case of a supersonic jet that big sonic boom that they hear, but it also occurs after explosions and can travel out far away from the you know that the typical fireball that you see. You could just be standing there and kind of feel like a pressure pulse and feel a little shaken up but fine the focus of my work has been trying to understand brain injuries from explosions in the military setting and what we know from the human experience is that people who do go through explosive events they’re predisposed to later development of neurodegenerative diseases like Alzheimer’s and Parkinson’s or mental health abnormalities like exactly anxiety and depression but we don’t really know what’s happening between the explosion and those things which can appear weeks to years later. So some of the work that I’ve been trying to do is use seeing laboratory research to figure out some of the early stage events that happen between the injury itself and then the later big problems that really can impact people’s lives. So this system will be good not to detect auditory systems in the brain damages but also perhaps also give some kind of window looking into the brain to see possibly other parts of the brain also damaged. Then we’ll have a early stage detection then you can tell these soldiers to maybe get on some kind of treatment early enough to prevent later unnecessary more serious damages. The goal for us is to take a look at say a high-risk population like a military unit who is combat deployed or going through training exercises that have explosions involved and then implementing simple easy-to-use screening profiles using easy non-invasive tests that could even though they might not have symptoms to report or things that can be identified by a physician there’s a test that could pick that up and say hey you’re at risk you don’t you might not know it but we should be looking out and trying to make some interventions.
