    R S Petersen
    Cognitive Neuroscience Sector, International School for Advanced Studies, Via Beirut 2 4, 34014 Trieste, Italy
    Neuron 32:503-14. 2001
    ..The barrel cortical population code for stimulus location appears to be the time of single neurons' first poststimulus spikes-a fast, robust coding mechanism that does not rely on "synergy" in crossneuronal spike patterns...

    Rasmus S Petersen
    Cognitive Neuroscience Sector, International School for Advanced Studies, Via Beirut 2 4, 34014, Trieste, Italy
    Curr Opin Neurobiol 12:441-7. 2002
    ..This may form the basis for a fast, robust population code...

    Rasmus S Petersen
    Cognitive Neuroscience Sector, International School for Advanced Studies, Via Beirut 2 4, 34014 Trieste, Italy
    Biosystems 67:187-93. 2002
    ..Spike patterns within individual cells played a smaller role; spike patterns across cells were negligible. This pattern of results was robust both to the exact nature of the stimulus set and to the precision at which spikes were binned...
  4. pmc Shifts in coding properties and maintenance of information transmission during adaptation in barrel cortex
    Miguel Maravall
    Instituto de Neurociencias de Alicante UMH CSIC, Campus de San Juan, Sant Joan d Alacant, Spain
    PLoS Biol 5:e19. 2007
    ..Our results suggest that adaptation enhances tactile representations in primary somatosensory cortex, where they could directly influence perceptual decisions...

    Mathew E Diamond
    Cognitive Neuroscience Sector, International School for Advanced Studies, Via Beirut 2 4, 34014 Trieste, Italy
    J Physiol Paris 97:529-36. 2003
    ..We also show that the topographic framework of primary sensory cortex renders the encoding of sensory information efficient, fast and reliable...

    Ehsan Arabzadeh
    Cognitive Neuroscience Sector, International School for Advanced Studies, 34014 Trieste, Italy
    J Neurosci 23:9146-54. 2003
    ..We conclude that vibration kinetics are rapidly and reliably encoded in the firing rate of cortical ensembles. Therefore, the cortical representation of vibration speed could underlie texture discrimination...

    Cognitive Neuroscience Sector, International School for Advanced Studies, Via Beirut, 9, 34014, Trieste, Italy
    Brain Res Bull 60:373-86. 2003
    ..It appears that abnormal sensory experience leads to alterations in the fine-tuning of cortical properties, but cortex is unexpectedly resistant to the effects of abnormal sensory and sensorimotor experience...

    Cereb Cortex 13:45-52. 2003
    ..Since such parcellation is present in some of the projections from barrel cortex, these findings suggest that columnar organization of barrel cortex serves to facilitate decoding of the location of the stimulated whisker...

    Faculty of Life Sciences, University of Manchester, The Mill, Manchester, UK
    J Neurophysiol 98:1871-82. 2007
