    • Auditory Conflict Resolution Correlates with Medial–Lateral Frontal Theta/Alpha Phase Synchrony 

      Huang, Samantha; Rossi, Stephanie; Hämäläinen, Matti; Ahveninen, Jyrki (Public Library of Science, 2014)
      When multiple persons speak simultaneously, it may be difficult for the listener to direct attention to correct sound objects among conflicting ones. This could occur, for example, in an emergency situation in which one ...
    • Auditory-Cortex Short-Term Plasticity Induced by Selective Attention 

      Jääskeläinen, Iiro P.; Ahveninen, Jyrki (Hindawi Publishing Corporation, 2014)
      The ability to concentrate on relevant sounds in the acoustic environment is crucial for everyday function and communication. Converging lines of evidence suggests that transient functional changes in auditory-cortex ...
    • Brain Networks of Novelty-Driven Involuntary and Cued Voluntary Auditory Attention Shifting 

      Huang, Samantha; Belliveau, John William; Tengshe, Chinmayi; Ahveninen, Jyrki Pekka (Public Library of Science, 2012)
      In everyday life, we need a capacity to flexibly shift attention between alternative sound sources. However, relatively little work has been done to elucidate the mechanisms of attention shifting in the auditory domain. ...
    • Dissociable Influences of Auditory Object vs. Spatial Attention on Visual System Oscillatory Activity 

      Ahveninen, Jyrki Pekka; Jääskeläinen, Iiro P.; Belliveau, John William; Hämäläinen, Matti; Lin, Fa-Hsuan; Raij, Tommi A. (Public Library of Science, 2012)
      Given that both auditory and visual systems have anatomically separate object identification (“what”) and spatial (“where”) pathways, it is of interest whether attention-driven cross-sensory modulations occur separately ...
    • Evidence for distinct human auditory cortex regions for sound location versus identity processing 

      Ahveninen, Jyrki; Huang, Samantha; Nummenmaa, Aapo; Belliveau, John W.; Hung, An-Yi; Jääskeläinen, Iiro P.; Rauschecker, Josef P.; Rossi, Stephanie; Tiitinen, Hannu; Raij, Tommi (2014)
      Neurophysiological animal models suggest that anterior auditory cortex (AC) areas process sound-identity information, whereas posterior ACs specialize in sound location processing. In humans, inconsistent neuroimaging ...
    • Increasing fMRI Sampling Rate Improves Granger Causality Estimates 

      Lin, Fa-Hsuan; Ahveninen, Jyrki; Raij, Tommi; Witzel, Thomas; Chu, Ying-Hua; Jääskeläinen, Iiro P.; Tsai, Kevin Wen-Kai; Kuo, Wen-Jui; Belliveau, John W. (Public Library of Science, 2014)
      Estimation of causal interactions between brain areas is necessary for elucidating large-scale functional brain networks underlying behavior and cognition. Granger causality analysis of time series data can quantitatively ...
    • Neural mechanisms supporting evaluation of others’ errors in real-life like conditions 

      Jääskeläinen, Iiro P.; Halme, Hanna-Leena; Agam, Yigal; Glerean, Enrico; Lahnakoski, Juha M; Sams, Mikko; Tapani, Karoliina; Ahveninen, Jyrki; Manoach, Dara S. (Nature Publishing Group, 2016)
      The ability to evaluate others’ errors makes it possible to learn from their mistakes without the need for first-hand trial-and-error experiences. Here, we compared functional magnetic resonance imaging activation to ...
