walter: the areas most honorable are these temporal lobes and , the limbic circuit emotion.io fall rightcomplaintso the category of these symptoms. susan: sports the vast majority of thects to the head result of a combination of linear and rotational movement of the head. research shows that the rotational movement of the head causes the largest amount of sloshing within the skull. of those very causes anerve fibers interruption in their ability to communicate among different areas of the brain. distortions in the brain cause serious brain injuries. as a bioengineer i use animals and i use computational models to look inside the head and make the relationships between the amount of brain distortion in the amount of disruption. thatve a lot of research has happened over the years about serious brain injuries. those more subtle changes that concussion, we really have very little understanding of how much distortion does it take to cause concussion symptoms. that research is very much under way. it is difficult to measure some of those subtle changes. dr. kandel: some of these changes are not reflect

. >> the temporal lobes, the frontal lobes, the limbic scirkt for emotion, depression, and these executive functions which are planning, attention. so all tori's complaints fall right down these particular brain regions. >> rose: nothing she said surprises you? >> no, i've heard this hundreds of times. >> rose: susan, what about the biomechanics? >> we'll go back to the image eric has shown before. in sports, the vast majority of impact to the head, and tori described impacts to another player, to the ground, a combination of linear and rotational movement of the head. researchers have shown the rotational movement causes the largest amount of sloshing of the brain within the skull. tom had described how the distortions of those very delicate axons or nerve fibers in the brain, when they're distorted, there is an interruption in their ability to communicate with the different regions of the brain. we do know big distortions in the brain cause serious brain injuries, but as a bioengineer, use animals and computational models to look inside the head and try to make the relationships between

temple owls look to continue the dream in the americanage limbic conference game. >> 10-2 headed to houston to face 11-1 kuing arizona and a win today would accepted them to one of the big six new year's bowl game. you can imagine a bowl game. how exciting is that? kickoff at noon and both the drop house an temple campus and piazza courtyard are hosting viewing parties. if you want to go out and have some excitement. >> this is pretty darn amazing a gift of hearing we all take it for graptd we can hear, until you lose it. there was a little girl that could not heard until mobile doctors at chop did amazing stuff. wait until you see what happened when should hears her mom's voice for the very first time. >> it's that time of year doing holiday shopping you may notice some changes have taken place at the checkout counter and what you need to know before you make your purchases. >> and look at here oh, my god. >> hi. >> hi mike, hi axe ex. we can't let you have all the fun. >> we wanted to check in and see how it's go going. >> we watched the first ten minutes of the show. >> use the #fox29wee
