  1. ncbi request reprint Speed of processing in the human visual system
    S Thorpe
    Centre de Recherche Cerveau and Cognition, Toulouse, France
    Nature 381:520-2. 1996
    ..ERP analysis revealed a frontal negativity specific to no-go trials that develops roughly 150 ms after stimulus onset. We conclude that the visual processing needed to perform this highly demanding task can be achieved in under 150 ms...
  2. doi request reprint Rapid visual categorization of natural scene contexts with equalized amplitude spectrum and increasing phase noise
    Olivier R Joubert
    Centre de Recherche Cerveau et Cognition, Universite de Toulouse, UPS, France
    J Vis 9:2.1-16. 2009
    ..This two-phase strategy could maximize categorization performance if the diagnostic features of man-made environments tolerate higher levels of noise than natural features, as proposed recently...
  3. doi request reprint Early interference of context congruence on object processing in rapid visual categorization of natural scenes
    Olivier R Joubert
    UPS, Centre de Recherche Cerveau et Cognition CNRS, CerCo, Universite de Toulouse, Toulouse, France
    J Vis 8:11.1-18. 2008
    ..Facilitation would be induced by the customary co-activation of "congruent" populations of neurons whereas interference would take place when conflictual populations of neurons fire simultaneously...
  4. ncbi request reprint Processing scene context: fast categorization and object interference
    Olivier R Joubert
    Universite, Toulouse 3, CerCo, UPS, France
    Vision Res 47:3286-97. 2007
    ..These data also suggest early interactions between scene and object representations compatible with contextual influences on object categorization in a parallel network...

    Denis Fize
    Centre de Recherche Cerveau and Cognition UMR 5549, CNRS UPS, Faculte de Medecine de Rangueil, 133 route de Narbonne, 31062 Toulouse, France
    Brain Cogn 59:145-58. 2005
    ..Latencies, slopes, and peak amplitudes of this differential activity were invariant to stimulus position and attentional load. Stimulus location uncertainty and lateralization did not affect speed of visual processing...

    Katrien Denys
    K U Leuven Medical School, B 3000 Leuven, Belgium
    J Cogn Neurosci 16:1505-16. 2004

    Neuropsychologia 41:1757-68. 2003
