      Previous work has shown that acupuncture stimulation evokes deactivation of a limbic-paralimbic-neocortical network (LPNN) as well as activation of somatosensory brain regions. This study explores the activity and functional ...

    • Brain encoding of acupuncture sensation — Coupling on-line rating with fMRI

      Napadow, Vitaly J.; Sheehan, J.; Kim, Jieun; Dassatti, Allison; Thurler, Andrea H.; Surjanhata, Brian; Vangel, Mark G.; Makris, Nikolaos; Schaechter, Judith Diane; Kuo, Braden (Wiley, 2013)
      Nausea is associated with significant morbidity, and there is a wide range in the propensity of individuals to experience nausea. The neural basis of this heterogeneity in nausea susceptibility is poorly understood. Our ...

    • Change in Brainstem Gray Matter Concentration Following a Mindfulness-Based Intervention is Correlated with Improvement in Psychological Well-Being 

      Singleton, Omar; Hölzel, Britta K.; Vangel, Mark; Brach, Narayan; Carmody, James; Lazar, Sara W. (Frontiers Media S.A., 2014)
      Individuals can improve their levels of psychological well-being (PWB) through utilization of psychological interventions, including the practice of mindfulness meditation, which is defined as the non-judgmental awareness ...

    • Characterization of the "Deqi" Response in Acupuncture 

      Liu, Jing; Hui, Kathleen; Nixon, Erika; Vangel, Mark; Marina, Ovidiu; Napadow, Vitaly; Hodge, Steven; Rosen, Bruce; Makris, Nikos; Kennedy, David (Springer Science and Business Media LLC, 2007-10-31)
      Background: Acupuncture stimulation elicits deqi, a composite of unique sensations that is essential for clinical efficacy according to traditional Chinese medicine (TCM). There is lack of adequate experimental data to ...

    • Default mode network connectivity encodes clinical pain: An arterial spin labeling study 

      Loggia, Marco Luciano; Kim, Jieun; Gollub, Randy Lyanne; Vangel, Mark G.; Kirsch, Irving; Kong, Jian; Wasan, Ajay D.; Napadow, Vitaly J. (Ovid Technologies (Wolters Kluwer Health), 2013)
      Neuroimaging studies have suggested the presence of alterations in the anatomo-functional properties of the brain of patients with chronic pain. However, investigation of the brain circuitry supporting the perception of ...

    • Differences in cortical response to acupressure and electroacupuncture stimuli 

      Witzel, Thomas; Napadow, Vitaly J.; Kettner, Norman W; Vangel, Mark G.; Hamalainen, Matti S.; Dhond, Rupali P (Springer Nature, 2011)
      Background FMRI studies focus on sub-cortical effects of acupuncture stimuli. The purpose of this study was to assess changes in primary somatosensory (S1) activity over the course of different types of acupuncture ...

    • Disentangling linear and nonlinear brain responses to evoked deep tissue pain 

      Loggia, Marco Luciano; Edwards, Robert R; Kim, Jieun; Vangel, Mark G.; Wasan, Ajay D.; Gollub, Randy Lyanne; Harris, Richard E.; Park, Kyungmo; Napadow, Vitaly J. (Ovid Technologies (Wolters Kluwer Health), 2012)
      Pain stimuli evoke widespread responses in the brain. However, our understanding of the physiological significance underlying heterogeneous response within different pain-activated and -deactivated regions is still limited. ...

    • Dissociable Genetic Contributions to Error Processing: A Multimodal Neuroimaging Study 

      Agam, Yigal; Vangel, Mark; Roffman, Joshua L.; Gallagher, Patience J.; Chaponis, Jonathan; Haddad, Stephen; Goff, Donald C.; Greenberg, Jennifer L.; Wilhelm, Sabine; Smoller, Jordan W.; Manoach, Dara S. (Public Library of Science, 2014)
      Background: Neuroimaging studies reliably identify two markers of error commission: the error-related negativity (ERN), an event-related potential, and functional MRI activation of the dorsal anterior cingulate cortex ...

    • Fibromyalgia is characterized by altered frontal and cerebellar structural covariance brain networks 

      Kim, Hyungjun; Kim, Jieun; Loggia, Marco L.; Cahalan, Christine; Garcia, Ronald G.; Vangel, Mark G.; Wasan, Ajay D.; Edwards, Robert R.; Napadow, Vitaly (Elsevier, 2015)
      Altered brain morphometry has been widely acknowledged in chronic pain, and recent studies have implicated altered network dynamics, as opposed to properties of individual brain regions, in supporting persistent pain. ...

    • Hypothalamus and amygdala response to acupuncture stimuli in carpal tunnel syndrome 

      Napadow, Vitaly J.; Kettner, N.; Liu, J.; Li, M.; Kwong, Kenneth Kin Man; Vangel, Mark G.; Makris, Nikolaos; Audette, Joseph F.; Hui, K. K.S. (Ovid Technologies (Wolters Kluwer Health), 2007)
