    • Brain functional networks in syndromic and non-syndromic autism: a graph theoretical study of EEG connectivity 

      Peters, Jurriaan M.; Taquet, Maxime; Vega, Clemente; Jeste, Shafali S; Fernández, Iván; Tan, Jacqueline E; Nelson, Charles A.; Sahin, Mustafa; Warfield, Simon Keith (Springer Science + Business Media, 2013)
      Background Graph theory has been recently introduced to characterize complex brain networks, making it highly suitable to investigate altered connectivity in neurologic disorders. A current model proposes autism spectrum ...

    • An In Vivo MRI Study of Prefrontal Cortical Complexity in First-Episode Psychosis 

      Wiegand, Laura C.; Warfield, Simon Keith; Levitt, James Jonathan; Hirayasu, Yoshio; Salisbury, Dean F.; Heckers, Stephan; Bouix, Sylvain; Schwartz, Daniel; Spencer, Magdalena; Dickey, Chandlee C.; Kikinis, Ron; Jolesz, Ferenc A.; McCarley, Robert William; Shenton, Martha Elizabeth (American Psychiatric Publishing, 2005)
      Objective: The purpose of this study was to investigate abnormalities in the surface complexity of the prefrontal cortex and in the hemispheric asymmetry of cortical complexity in first-episode patients with schizophrenia. ...

    • Localization of the Epileptogenic Foci in Tuberous Sclerosis Complex: A Pediatric Case Report 

      Hunold, Alexander; Haueisen, Jens; Ahtam, Banu; Doshi, Chiran; Harini, Chellamani; Camposano, Susana; Warfield, Simon K.; Grant, Patricia Ellen; Okada, Yoshio; Papadelis, Christos (Frontiers Media S.A., 2014)
      Tuberous sclerosis complex (TSC) is a rare disorder of tissue growth and differentiation, characterized by benign hamartomas in the brain and other organs. Up to 90% of TSC patients develop epilepsy and 50% become medically ...

    • Morphological Characteristics of Brain Tumors Causing Seizures 

      Lee, Jong Woo; Wen, Patrick Yung Chih; Hurwitz, Shelley; Black, Peter McLaren; Kesari, Santosh; Drappatz, Jan; Golby, Alexandra Jacqueline; Wells, William Mercer; Warfield, Simon Keith; Kikinis, Ron; Bromfield, Edward B. (American Medical Association (AMA), 2010)
      Objective: To quantify size and localization differences between tumors presenting with seizures vs nonseizure neurological symptoms. Design: Retrospective imaging survey. We performed magnetic resonance imaging–based ...

    • NIDCAP improves brain function and structure in preterm infants with severe intrauterine growth restriction 

      Als, Heidelise; Duffy, Frank Hopkins; McAnulty, Gloria; Butler, Samantha C.; Lightbody, L; Kosta, S; Weisenfeld, Neil I; Robertson, Richard Lee; Parad, Richard Barry; Ringer, Steven Alan; Blickman, J G; Zurakowski, David; Warfield, Simon Keith (Nature Publishing Group, 2012)
      Objective: The effect of NIDCAP (Newborn Individualized Developmental Care and Assessment Program) was examined on the neurobehavioral, electrophysiological and neurostructural development of preterm infants with severe ...

    • Prefrontal cortical thickness in first-episode psychosis: a magnetic resonance imaging study 

      Wiegand, Laura C; Warfield, Simon Keith; Levitt, James Jonathan; Hirayasu, Yoshio; Salisbury, Dean F; Heckers, Stephan; Dickey, Chandlee C.; Kikinis, Ron; Jolesz, Ferenc A.; McCarley, Robert William; Shenton, Martha Elizabeth (Elsevier BV, 2004)
      Background: Findings from postmortem studies suggest reduced prefrontal cortical thickness in schizophrenia; however, cortical thickness in first-episode schizophrenia has not been evaluated using magnetic resonance imaging ...

    • School-age effects of the newborn individualized developmental care and assessment program for preterm infants with intrauterine growth restriction: preliminary findings 

      McAnulty, Gloria; Duffy, Frank Hopkins; Kosta, Sandra; Weisenfeld, Neil I; Warfield, Simon Keith; Butler, Samantha C.; Alidoost, Moona; Bernstein, Jane Holmes; Robertson, Richard Lee; Zurakowski, David; Als, Heidelise (BioMed Central, 2013)
      Background: The experience in the newborn intensive care nursery results in premature infants’ neurobehavioral and neurophysiological dysfunction and poorer brain structure. Preterms with severe intrauterine growth restriction ...

    • Serial FEM/XFEM-Based Update of Preoperative Brain Images Using Intraoperative MRI 

      Vigneron, Lara M.; Noels, Ludovic; Warfield, Simon Keith; Verly, Jacques G.; Robe, Pierre A. (Hindawi Publishing Corporation, 2012)
      Current neuronavigation systems cannot adapt to changing intraoperative conditions over time. To overcome this limitation, we present an experimental end-to-end system capable of updating 3D preoperative images in the ...
