    Abstract:
    Some structural and functional characteristics of the dorsolateral prefrontal cortex and corpus callosum genu were analyzed in comparison with electrophysiological markers of selective attention in 18 mentally healthy subjects and 22 remitted patients with juvenile schizophrenia. In both topography zones there were no statistically significant intergroup differences in N-acetylaspartate and choline compounds (by proton MR-spectroscopy), whereas fractional anisotropy (by diffusion tensor imaging) in the corpus callosum genu was lower in patients. Absence of significant correlations between the imaging characteristics and psychopathology scores and their weak correlations with P300 suggest a poor involvement of the analyzed structures in the processes which determine cognitive disorders in patients with juvenile schizophrenia.
