Representation of lateralization and tonotopy in primary versus secondary human auditory cortex

Dave R.M. Langers, Walter H. Backes, Pim van Dijk
2007 NeuroImage  
Functional MRI was performed to investigate differences in the basic functional organization of the primary and secondary auditory cortex regarding preferred stimulus lateralization and frequency.  ...  This suggests a neural re-encoding of sound signals in the transition from primary to secondary areas, possibly in relation to auditory scene analysis and the processing of auditory objects.  ...  Furthermore, the authors would like to acknowledge the contribution of L. Speelman, who participated in the development of some of the initial data processing routines.  ...

Neuromagnetic indicators of auditory cortical reorganization of tinnitus

Nathan Weisz, Christian Wienbruch, Katalin Dohrmann, Thomas Elbert
2005 Brain  
Overall, the present study suggests that mechanisms of map reorganization, although present in the data, cannot satisfactorily explain the emergence of tinnitus and that differential hemispheric involvement  ...  Animal studies show that following damage to inner-ear receptors, central representations of intact lesion-edge (LE) frequencies become enlarged (map reorganization).  ...  This study was financed by a grant of the Deutsche Forschungsgemeinschaft (DFG EL101/21).  ...

Thalamic and cortical pathways supporting auditory processing

Charles C. Lee
2013 Brain and Language  
Here, the general organization of these connections in the medial geniculate body (thalamus) and the auditory cortex is reviewed.  ...  In addition, we consider two models organizing the thalamocortical pathways of the non-tonotopic and multimodal auditory nuclei.  ...  The lateralization of auditory cortical processing for speech and language appears unique to humans, yet it remains unclear how concomitant neuroanatomical specializations in the cortex and thalamus underlie  ...
