    G Karmos
    Institute for Psychology of the Hungarian Academy of Sciences, P O Box 398, H 1394 Budapest, Hungary
    Acta Biol Hung 53:473-83. 2002
    ..We conclude that both the SSR and the spontaneous gamma activity reflect resonant activity of the same neuronal circuit of the auditory cortex, and it is modulated by the motivational state of the animal...

    Istvan Ulbert
    Institute of Experimental Medicine of the Hungarian Academy of Sciences, Budapest 1450, Hungary
    Exp Neurol 187:310-8. 2004
    ..Electrophysiological identification of the functional state of the hippocampus together with its local structural correlates could further enhance our understanding of this disease...
  3. ncbi request reprint Multiple microelectrode-recording system for human intracortical applications
    I Ulbert
    Institute for Psychology of the Hungarian Academy of Sciences, Budapest, Hungary
    J Neurosci Methods 106:69-79. 2001
    ..The current paper presents details of a system meeting these criteria, together with sample results obtained from epileptic subjects undergoing acute or chronic intracranial monitoring for definition of the epileptogenic region...
  4. ncbi request reprint Separation of mismatch negativity and the N1 wave in the auditory cortex of the cat: a topographic study
    Z Pincze
    Institute for Psychology of the Hungarian Academy of Sciences, Budapest, Hungary
    Clin Neurophysiol 112:778-84. 2001
    ..The amplitude distribution of the frequency mismatch negativity (MMN) and that of P1 and N1 components were investigated in cats to reveal their sources in the auditory areas of the neocortex...
  5. ncbi request reprint Early discrimination of coherent versus incoherent motion by multiunit and synaptic activity in human putative MT+
    I Ulbert
    Institute for Psychology, Hungarian Academy of Sciences, Budapest, Hungary
    Hum Brain Mapp 13:226-38. 2001
    ..Thus, while estimates of total cell firing (MUA), and of total synaptic activity (CSD) generally correspond to previously reported BOLD results, they may differ in important details...
  6. ncbi request reprint Modelling the magnetic signature of neuronal tissue
    K B Blagoev
    Theoretical Division, Los Alamos National Laboratory, Los Alamos, NM 87544, USA
    Neuroimage 37:137-48. 2007
    ..MRI contrast generation based on neuronal currents depends on the dendritic architecture and we obtained high-resolution optical images of cortical tissue to discuss the spatial structure of the magnetic field in grey matter...
