Impact of the gyral geometry on the electric field induced by transcranial magnetic stimulationAxel Thielscher
High Field Magnetic Resonance Center, MPI for Biological Cybernetics, Tubingen, Germany
Neuroimage 54:234-43. 2011..In contrast to the clear-cut effects of the gyrification pattern on the induced field strength, current directions were predominantly influenced by the CSF-skull boundary...- The cortical site of visual suppression by transcranial magnetic stimulationA Thielscher
High Field Magnetic Resonance Center, Max Planck Institute for Biological Cybernetics, 72076 Tubingen, Germany
Cereb Cortex 20:328-38. 2010..These findings support the view that intact activity patterns in several early visual areas (rather than merely in V1) are likewise important for the perception of the stimulus... - Determining the cortical target of transcranial magnetic stimulationA Thielscher
High Field Magnetic Resonance Center, Max Planck Institute for Biological Cybernetics, Tubingen, Germany
Neuroimage 47:1319-30. 2009..The estimates for the field strength necessary to achieve 50% of the maximal suppression effect vary noticeably across subjects (mean+/-SD: 139+/-24 V/m), indicating inter-individual differences in the susceptibility to TMS... - Globally consistent depth sorting of overlapping 2D surfaces in a model using local recurrent interactionsAxel Thielscher
High Field Magnetic Resonance Center, Max Planck Institute for Biological Cybernetics, Spemannstrasse 38, Tubingen, Germany
Biol Cybern 98:305-37. 2008..Within this framework, the induction of illusory contours by the model of recurrent V1-V2 interaction gives rise to the figure-ground segmentation of illusory figures such as a Kanizsa square...

Department of Psychiatry, University of Ulm, Ulm, Germany
J Comput Neurosci 22:255-82. 2007..In particular, feedback interaction is crucial to raise the model performance to the level of human observers...- The navigation of transcranial magnetic stimulationU Herwig
Department of Psychiatry, University of Ulm, Leimgrubenweg 12, D 89070 Ulm, Germany
Psychiatry Res 108:123-31. 2001..Future applications of TMS should take individual anatomy into account, and neuronavigation provides the means to do so... - Texture segmentation in human perception: a combined modeling and fMRI studyA Thielscher
Max Planck Institute for Biological Cybernetics, Tuebingen, Germany
Neuroscience 151:730-6. 2008..Our modeling and imaging results indicate that mid-level visual areas form a key stage in figure-ground segregation by gradually signaling the salience of region boundaries defined by orientation contrast... - Effects of transcranial magnetic stimulation on visual evoked potentials in a visual suppression taskA Reichenbach
Magnetic Resonance Center, MPI for Biological Cybernetics, Tubingen, Germany
Neuroimage 54:1375-84. 2011..Importantly, however, this effect is uncorrelated with the strength of behavioral impairment... - Motor thresholds in humans: a transcranial magnetic stimulation study comparing different pulse waveforms, current directions and stimulator typesT Kammer
