We aimed to investigate the potential impact of low-level blast exposure during breacher training on the neural functioning of working memory and auditory network connectivity. We also aimed to evaluate the effects of a jugular vein compression collar, designed to internally mitigate slosh energy absorption, preserving neural functioning and connectivity, following blast exposure. A total of 23 SWAT personnel were recruited and randomly assigned to a non-collar (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200911) and collar group (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200912). All participants completed a 1-day breacher training with multiple blast exposure. Prior to and following training, 18 participants (non-collar,\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u20098; collar,\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200910) completed functional magnetic resonance imaging (fMRI) of working memory using N-Back task; 20 participants (non-collar,\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200910; collar,\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200912) completed resting-state fMRI. Key findings from the working memory analysis include significantly increased fMRI brain activation in the right insular, right superior temporal pole, right inferior frontal gyrus, and pars orbitalis post-training for the non-collar group (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05, threshold-free cluster enhancement corrected), but no changes were noted for the collar group. The elevation in fMRI activation in the non-collar group was found to correlate significantly (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u20097,\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    \u2009=\u20090.943,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.001) with average peak impulse amplitude experienced during the training. In the resting-state fMRI analysis, significant pre- to post-training increase in connectivity between the auditory network and two discrete regions (left middle frontal gyrus and left superior lateral occipital\/angular gyri) was found in the non-collar group, while no change was observed in the collar group. These data provided initial evidence of the impact of low-level blast on working memory and auditory network connectivity as well as the protective effect of collar on brain function following blast exposure, and is congruent with previous collar findings in sport-related traumatic brain injury.\n                  <\/jats:p>","DOI":"10.1089\/neu.2018.5737","type":"journal-article","created":{"date-parts":[[2018,8,23]],"date-time":"2018-08-23T07:20:37Z","timestamp":1535008837000},"page":"721-734","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Impact of Low-Level Blast Exposure on Brain Function after a One-Day Tactile Training and the Ameliorating Effect of a Jugular Vein Compression Neck Collar Device"],"prefix":"10.1177","volume":"36","author":[{"given":"Weihong","family":"Yuan","sequence":"first","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"},{"name":"University of Cincinnati College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim D.","family":"Barber Foss","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Dudley","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Staci","family":"Thomas","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Galloway","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"DiCesare","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Leach","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"},{"name":"University of Cincinnati College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pete","family":"Scheifele","sequence":"additional","affiliation":[{"name":"University of Cincinnati"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Farina","sequence":"additional","affiliation":[{"name":"University of Cincinnati"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gloria","family":"Valencia","sequence":"additional","affiliation":[{"name":"University of Cincinnati"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Smith","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mekibib","family":"Altaye","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher K.","family":"Rhea","sequence":"additional","affiliation":[{"name":"University of North Carolina at Greensboro"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Talavage","sequence":"additional","affiliation":[{"name":"Purdue University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory D.","family":"Myer","sequence":"additional","affiliation":[{"name":"Cincinnati Children's Hospital Medical Center"},{"name":"University of Cincinnati"},{"name":"The Micheli Center for Sports Injury Prevention"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,2,22]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"Defense and Veterans Brain Injury Center.
