- Cortical representation of vowels reflects acoustic dissimilarity determined by formant frequenciesJonas Obleser
University of Konstanz, Department of Clinical Psychology, P O Box D25, 78457 Konstanz, Germany
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...
- Vowel sound extraction in anterior superior temporal cortexJonas Obleser
Fachgruppen Psychologie und Linguistik, Universitat Konstanz, 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...
- Auditory-evoked magnetic field codes place of articulation in timing and topography around 100 milliseconds post syllable onsetJonas Obleser
Department of Clinical Psychology, University of Konstanz, 78457 Konstanz, Germany
Neuroimage 20:1839-47. 2003....
- Magnetic brain response mirrors extraction of phonological features from spoken vowelsJonas Obleser
University of Konstanz, Universitatstrasse 10, PO Box D25, 78457 Konstanz, Germany
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...
- Attentional influences on functional mapping of speech sounds in human auditory cortexJonas Obleser
Department of Psychology, University of Konstanz, Germany
BMC Neurosci 5:24. 2004..Auditory evoked fields were recorded using 148-channel magnetoencephalography (MEG), and magnetic source imaging was obtained for 17 subjects...
- Gender differences in hemispheric asymmetry of syllable processing: left-lateralized magnetic N100 varies with syllable categorization in femalesJonas Obleser
Department of Clinical Psychology, University of Konstanz, Germany
Psychophysiology 41:783-8. 2004..Only in females did the degree of left-lateralization predict successful syllable categorization from short syllable bursts: Results suggest gender-specific differences in spectro-temporal analysis of speech...
- Intra-subject replication of brain magnetic activity during the processing of speech soundsCarsten Eulitz
Department of Clinical Psychology, University of Konstanz, Giessberg 10, P O Box D25, 78457 Konstanz, Germany

- Auditory evoked fields differentially encode speech features: an MEG investigation of the P50m and N100m time courses during syllable processingKambiz Tavabi
Institute for Biomagnetism and Biosignalanalysis, University of Munster, Germany
Eur J Neurosci 25:3155-62. 2007..Moreover, the observations substantiate the assumption that the N100m response reflects a more abstract phonological representational stage during speech perception...
- Functional integration across brain regions improves speech perception under adverse listening conditionsJonas 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...
- Multiple stages of auditory speech perception reflected in event-related FMRIJonas Obleser
Georgetown University School of Medicine, Georgetown University, Washington, DC, USA
Cereb Cortex 17:2251-7. 2007..Multistage hierarchical processing of speech sounds is thus revealed with fMRI, providing evidence for a role of the PT in the fundamental stages of the acoustic analysis of complex sounds, including speech...
- Now you hear it, now you don't: transient traces of consonants and their nonspeech analogues in the human brainJonas Obleser
Institute of Cognitive Neuroscience, University College London, 17 Queen Square, London, WC1N 3AR, UK
Cereb Cortex 16:1069-76. 2006....
- Bilateral speech comprehension reflects differential sensitivity to spectral and temporal featuresJonas Obleser
Max Planck Institute for Human Cognitive and Brain Sciences, 04103 Leipzig, Germany
J Neurosci 28:8116-23. 2008..Applying direct manipulations to the speech signal rather than to low-level surrogates, the results lend plausibility to the notion of complementary roles for the left and right superior temporal sulci in comprehending the speech signal...
