    P Helenius
    Brain Research Unit, Low Temperature Laboratory, Helsinki University of Technology, Espoo, Finland
    Cereb Cortex 9:476-83. 1999
    ..Thus, while the early visual processing seems intact in dyslexic adults, the pattern of cortical activation starts to differ from that of fluent readers at the point where letter-string-specific signals first emerge during reading...
  2. doi request reprint Neural correlates of late positivities associated with infrequent visual events and response errors
    Päivi Helenius
    Brain Research Unit, MEG Core, Low Temperature Laboratory, Aalto University, Espoo, Finland
    Neuroimage 53:619-28. 2010
    ..The negative ERP components evoked by NoGo stimuli (N2) and erroneous responses (ERN) were found to be associated with partly non-overlapping neural sources...

    Brain Research Unit, Low Temperature Laboratory, Helsinki University of Technology, Espoo, Finland
    Brain 132:1918-27. 2009
    ..e. when advancing from milder to more severe language impairment. The unusually rapid decay of speech-evoked activation could have a detrimental role on vocabulary growth in children with SLI...

    Jennifer M Thomson
    Institute of Child Health, University College London, London, England
    Mem Cognit 33:1210-9. 2005
    ..We report significant rime neighborhood density effects for serial recall of both words and nonwords, for both dyslexic and typically developing children...

    Usha Goswami
    Faculty of Education, University of Cambridge, Cambridge CB2 2PQ, UK
    J Exp Child Psychol 92:345-65. 2005

    Päivi Helenius
    Brain Research Unit, MEG Core, Low Temperature Laboratory, Aalto University, Espoo, Finland
    Neuropsychologia 49:1889-96. 2011
    ..We suggest that the activation in the superior temporal cortices during the LPC reflects the action of ventral attention network. The engagement of this stimulus-driven reorienting system is defective in ADHD...

    J Neurosci 22:2936-44. 2002

    Paavo H T Leppanen
    Department of Psychology, University of Jyvaskyla, Finland
    Dev Neuropsychol 22:407-22. 2002

    Ulla Richardson
    Faculty of Education, University of Cambridge, UK
    Dyslexia 10:215-33. 2004
    ..It is argued that developmentally, amplitude envelope cues may be primary in establishing well-specified phonological representations, as these cues should yield important rhythmic and syllable-level information about speech...
