• Frontoamygdala hyperconnectivity predicts affective dysregulation in adolescent moderate-severe TBI 

      Bickart, Kevin C.; Olsen, Alexander; Dennis, Emily L.; Babikian, Talin; Hoffman, Ann N.; Snyder, Aliyah; Sheridan, Christopher A.; Fischer, Jesse T.; Giza, Christopher C.; Choe, Meeryo C.; Asarnow, Robert F. (Peer reviewed; Journal article, 2022)
      In survivors of moderate to severe traumatic brain injury (msTBI), affective disruptions often remain underdetected and undertreated, in part due to poor understanding of the underlying neural mechanisms. We hypothesized ...
    • Functional Brain Hyperactivations Are Linked to an Electrophysiological Measure of Slow Interhemispheric Transfer Time after Pediatric Moderate/Severe Traumatic Brain Injury 

      Olsen, Alexander; Babikian, Talin; Dennis, Emily L.; Ellis-Blied, Monica U.; Giza, Christopher C.; Marion, Sarah DeBoard; Mink, Richard; Johnson, Jeffrey; Babbitt, Christopher; Thompson, Paul M.; Asarnow, Robert F. (Peer reviewed; Journal article, 2020)
      Increased task-related blood oxygen level dependent (BOLD) activation is commonly observed in functional magnetic resonance imaging (fMRI) studies of moderate/severe traumatic brain injury (msTBI), but the functional ...
    • Magnetic resonance spectroscopy of fiber tracts in children with traumatic brain injury: A combined MRS - Diffusion MRI study 

      Dennis, Emily L.; Babikian, Talin; Alger, Jeffry; Rashid, Faisal; Villalon-Reina, Julio E.; Jin, Yan; Olsen, Alexander; Mink, Richard; Babbitt, Christopher; Johnson, Jeffrey; Giza, Christopher C.; Thompson, Paul M.; Asarnow, Robert F. (Peer reviewed; Journal article, 2018)
      Traumatic brain injury can cause extensive damage to the white matter (WM) of the brain. These disruptions can be especially damaging in children, whose brains are still maturing. Diffusion magnetic resonance imaging (dMRI) ...
    • Multimodal Analysis of Secondary Cerebellar Alterations After Pediatric Traumatic Brain Injury 

      Keleher, Finian; Lindsey, Hannah; Kerestes, Rebecca; Amiri, Houshang; Asarnow, Robert; Babikian, Talin; Bartnik-Olson, Brenda L.; Bigler, Erin D; Caeyenberghs, Karen; Ewing-Cobbs, Linda; Giza, Christopher C.; Goodrich-Hunsaker, Naomi J; Hodges, Cooper B.; Hoskinson, Kristen R; Irimia, Andrei; Königs, Marsh; Max, Jeffrey; Newsome, Mary R; Olsen, Alexander; Ryan, Nicholas P; Schmidt, Adam T.; Stein, Dan J; Suskauer, Stacy J; Ware, Ashley L; Wheeler, Anne L; Zielinski, Brandon A; Thompson, Paul; Harding, Ian H.; Tate, David F.; Wilde, Elisabeth; Dennis, Emily L (Peer reviewed; Journal article, 2023)
      IMPORTANCE: Traumatic brain injury (TBI) is known to cause widespread neural disruption in the cerebrum. However, less is known about the association of TBI with cerebellar structure and how such changes may alter executive ...
    • Toward a global and reproducible science for brain imaging in neurotrauma: the ENIGMA adult moderate/severe traumatic brain injury working group 

      Olsen, Alexander; Babikian, Talin; Bigler, Erin D.; Caeyenberghs, Karen; Conde, Virginia; Dams-O’Connor, Kristen; Dobryakova, Ekaterina; Genova, Helen; Grafman, Jordan; Håberg, Asta; Heggland, Ingrid; Hellstrøm, Torgeir; Hodges, Cooper B.; Irimia, Andrei; Jha, Ruchira M.; Johnson, Paula K.; Koliatsos, Vassilis E.; Levin, Harvey; Li, Lucia M.; Lindsey, Hannah M.; Livny, Abigail; Løvstad, Marianne; Medaglia, John; Menon, David; Mondello, Stefania; Monti, Martin M.; Newcombe, Virginia F.J.; Petroni, Agustin; Ponsford, Jennie; Sharp, David; Spitz, Gershon; Westlye, Lars Tjelta; Thompson, Paul M.; Dennis, Emily L.; Tate, David; Wilde, Elisabeth A.; Hillary, Frank G. (Peer reviewed; Journal article, 2020)
      The global burden of mortality and morbidity caused by traumatic brain injury (TBI) is significant, and the heterogeneity of TBI patients and the relatively small sample sizes of most current neuroimaging studies is a major ...
