    • Action Initiation in the Human Dorsal Anterior Cingulate Cortex 

      Srinivasan, Lakshminarayan; Asaad, Wael F.; Ginat, Daniel T; Gale, John T.; Dougherty, Darin Dean; Williams, Ziv; Sejnowski, Terrence J.; Eskandar, Emad (Public Library of Science, 2013)
      The dorsal anterior cingulate cortex (dACC) has previously been implicated in processes that influence action initiation. In humans however, there has been little direct evidence connecting dACC to the temporal onset of ...

    • Are All Placebo Effects Equal? Placebo Pills, Sham Acupuncture, Cue Conditioning and Their Association 

      Kong, Jian; Spaeth, Rosa; Cook, Amanda; Kirsch, Irving; Claggett, Brian; Vangel, Mark; Gollub, Randy L.; Smoller, Jordan W.; Kaptchuk, Ted J. (Public Library of Science, 2013)
      Placebo treatments and healing rituals have been used to treat pain throughout history. The present within-subject crossover study examines the variability in individual responses to placebo treatment with verbal suggestion ...

    • Behavioral and Neural Correlates of Executive Functioning in Musicians and Non-Musicians 

      Zuk, Jennifer; Benjamin, Christopher; Kenyon, Arnold; Gaab, Nadine (Public Library of Science, 2014)
      Executive functions (EF) are cognitive capacities that allow for planned, controlled behavior and strongly correlate with academic abilities. Several extracurricular activities have been shown to improve EF, however, the ...

    • Computerized Cognitive Training with Older Adults: A Systematic Review 

      Kueider, Alexandra M.; Parisi, Jeanine M.; Gross, Alden L; Rebok, George W. (Public Library of Science, 2012)
      A systematic review to examine the efficacy of computer-based cognitive interventions for cognitively healthy older adults was conducted. Studies were included if they met the following criteria: average sample age of at ...

    • Impulsive Social Influence Increases Impulsive Choices on a Temporal Discounting Task in Young Adults 

      Gilman, Jodi M.; Curran, Max T.; Calderon, Vanessa; Stoeckel, Luke E.; Evins, A. Eden (Public Library of Science, 2014)
      Adolescents and young adults who affiliate with friends who engage in impulsive behavior are more likely to engage in impulsive behaviors themselves, and those who associate with prosocial (i.e. more prudent, future oriented) ...

    • Interaction of Sleep and Emotional Content on the Production of False Memories 

      McKeon, Shannon; Pace-Schott, Edward Franz; Spencer, Rebecca M. C. (Public Library of Science, 2012)
      Sleep benefits veridical memories, resulting in superior recall relative to off-line intervals spent awake. Sleep also increases false memory recall in the Deese-Roediger-McDermott (DRM) paradigm. Given the suggestion that ...

    • Multi-Scale Motility Amplitude Associated with Suicidal Thoughts in Major Depression 

      Indic, Premananda; Murray, Greg; Maggini, Carlo; Amore, Mario; Meschi, Tiziana; Borghi, Loris; Baldessarini, Ross John; Salvatore, Paola (Public Library of Science, 2012)
      Major depression occurs at high prevalence in the general population, often starts in juvenile years, recurs over a lifetime, and is strongly associated with disability and suicide. Searches for biological markers in ...

    • Neurocognitive and Somatic Components of Temperature Increases during g-Tummo Meditation: Legend and Reality 

      Kozhevnikov, Maria; Elliott, James; Shephard, Jennifer; Gramann, Klaus (Public Library of Science, 2013)
      Stories of g-tummo meditators mysteriously able to dry wet sheets wrapped around their naked bodies during a frigid Himalayan ceremony have intrigued scholars and laypersons alike for a century. Study 1 was conducted in ...

    • The Problem of Thresholding in Small-World Network Analysis 

      Langer, Nicolas; Pedroni, Andreas; Jäncke, Lutz (Public Library of Science, 2013)
      Graph theory deterministically models networks as sets of vertices, which are linked by connections. Such mathematical representation of networks, called graphs are increasingly used in neuroscience to model functional ...

    • Temporal Properties of Liquid Crystal Displays: Implications for Vision Science Experiments 

      Elze, Tobias; Tanner, Thomas G. (Public Library of Science, 2012)
      Liquid crystal displays (LCD) are currently replacing the previously dominant cathode ray tubes (CRT) in most vision science applications. While the properties of the CRT technology are widely known among vision scientists, ...
