    Brain Res Cogn Brain Res 15:207-13. 2003
    ..This pattern of results was reliably found in a second experimental session after at least 5 days. The results suggest the preservation of spectral dissimilarities as mapped in a F(1)-F(2) vowel space in a cortical representation...

    Jonas Obleser
    Fachgruppen Psychologie und Linguistik, , Konstanz, Germany
    Hum Brain Mapp 27:562-71. 2006
    ..These findings also support the notion of an auditory "what" stream, with highly object-specialized areas anterior to primary auditory cortex...

    J Cogn Neurosci 16:31-9. 2004
    ..In sum, results suggest that both N100m latency and source location as well as their interaction reflect properties of speech stimuli that correspond to abstract phonological features...
  5. ncbi Attentional influences on functional mapping of speech sounds in human auditory cortex
    Jonas Obleser
    Department of Psychology, University of Konstanz, Germany
    BMC Neurosci 5:24. 2004

    Jonas Obleser
    Department of Clinical Psychology, University of Konstanz, Germany

    Jonas Obleser
    Institute of Cognitive Neuroscience, University College London, London WC1N 3AR, United Kingdom
    J Neurosci 27:2283-9. 2007
    ..These results demonstrate that increasing functional connectivity between high-order cortical areas, remote from the auditory cortex, facilitates speech comprehension when the clarity of speech is reduced...
