    • 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. ...

    • The Effects of Methylphenidate on Cognitive Control in Active Methamphetamine Dependence Using Functional Magnetic Resonance Imaging 

      Jan, Reem K.; Lin, Joanne C.; McLaren, Donald G.; Kirk, Ian J.; Kydd, Rob R.; Russell, Bruce R. (Frontiers Media S.A., 2014)
      Methamphetamine (MA) dependence is associated with cognitive deficits. Methylphenidate (MPH) has been shown to improve inhibitory control in healthy and cocaine-dependent subjects. This study aimed to understand the ...

    • Probing Intrinsic Resting-State Networks in the Infant Rat Brain 

      Bajic, Dusica; Craig, Michael M.; Borsook, David; Becerra, Lino (Frontiers Media S.A., 2016)
      Resting-state functional magnetic resonance imaging (rs-fMRI) measures spontaneous fluctuations in blood oxygenation level-dependent (BOLD) signal in the absence of external stimuli. It has become a powerful tool for mapping ...

    • Systemic Low-Frequency Oscillations in BOLD Signal Vary with Tissue Type 

      Tong, Yunjie; Hocke, Lia M.; Lindsey, Kimberly P.; Erdoğan, Sinem B.; Vitaliano, Gordana; Caine, Carolyn E.; Frederick, Blaise deB. (Frontiers Media S.A., 2016)
      Blood-oxygen-level dependent (BOLD) signals are widely used in functional magnetic resonance imaging (fMRI) as a proxy measure of brain activation. However, because these signals are blood-related, they are also influenced ...
