  2. ncbi request reprint Mismatch negativity in aging and in Alzheimer's and Parkinson's diseases
    E Pekkonen
    Department of Neurology, Helsinki University Central Hospital, Finland

  3. ncbi request reprint Effects of haloperidol on selective attention: a combined whole-head MEG and high-resolution EEG study
    S Kahkonen
    BioMag Laboratory, Medical Engineering Centre, Helsinki University Central Hospital, Helsinki, Finland
    Neuropsychopharmacology 25:498-504. 2001
    ..Taken together, haloperidol seemed to induce functional changes in neural networks accounting for both selective and involuntary attention, suggesting modulation of these functions by dopamine D2 receptors...
  4. ncbi request reprint Replicability of MEG and EEG measures of the auditory N1/N1m-response
    J Virtanen
    Department of Psychology, University of Helsinki, Helsinki University Central Hospital, Finland
    Electroencephalogr Clin Neurophysiol 108:291-8. 1998
    ..The results suggest that both MEG and EEG can be used for investigating the simultaneous activity of the left and right auditory cortices independently, MEG being superior in certain experimental setups...
  5. ncbi request reprint Preserved stimulus deviance detection in Alzheimer's disease
    E Pekkonen
    Department of Neurology, University of Helsinki, and Medical Engineering Centre, Helsinki University Central Hospital, Finland
    Neuroreport 12:1649-52. 2001
    ..This suggests that although MMNm is delayed in the left hemisphere, the automatic discrimination to duration change in the auditory cortex is not attenuated in the early stages of AD...
  6. ncbi request reprint Scopolamine reduces the P35m and P60m deflections of the human somatosensory evoked magnetic fields
    J Huttunen
    BioMag Laboratory, Medical Engineering Centre, Helsinki University Central Hospital, Finland
    Neuroreport 12:619-23. 2001
