Topographic ERP Analyses: A Step-by-Step Tutorial Review
In this tutorial review, we detail both the rationale for as well as the implementation of a set of analyses of surface-recorded event-related potentials (ERPs) that uses the reference-free spatialExpand
EEG source imaging
It is shown that modern EEG source imaging simultaneously details the temporal and spatial dimensions of brain activity, making it an important and affordable tool to study the properties of cerebral, neural networks in cognitive and clinical neurosciences. Expand
Multisensory auditory-visual interactions during early sensory processing in humans: a high-density electrical mapping study.
This study examined the timing and topography of cortical auditory-visual interactions using high-density event-related potentials (ERPs) during a simple reaction-time (RT) task, providing compelling evidence that auditory- visual neural interactions give rise to this RT effect. Expand
Spatiotemporal Analysis of Multichannel EEG: CARTOOL
Methods to analyze the brain's electric fields recorded with multichannel Electroencephalogram (EEG) and their implementation in the software CARTOOL, designed to visualize the data and the analysis results using 3-dimensional display routines that allow rapid manipulation and animation of 3D images.

Grabbing your ear: rapid auditory-somatosensory multisensory interactions in low-level sensory cortices are not constrained by stimulus alignment.
Psychophysical and electrophysiological indices are used to show that auditory-somatosensory interactions in humans occur via the same early sensory mechanism both when stimuli are in and out of spatial register, and across wide peripersonal spatial separations remarkably early in sensory processing and in cortical regions traditionally considered unisensory. Expand
Multisensory auditory-somatosensory interactions in early cortical processing revealed by high-density electrical mapping.
Both the topography and timing of these interactions are consistent with multisensory integration early in the cortical processing hierarchy, in brain regions traditionally held to be un isensory. Expand
The Spatiotemporal Dynamics of Illusory Contour Processing: Combined High-Density Electrical Mapping, Source Analysis, and Functional Magnetic Resonance Imaging
It is proposed that IC sensitivity described in V2 and V1 may reflect predominantly feedback modulation from higher-tier LOC areas, where IC sensitivity first occurs, and two additional observations further support this proposal. Expand
Attention-dependent suppression of distracter visual input can be cross-modally cued as indexed by anticipatory parieto-occipital alpha-band oscillations.
The results of this series of studies suggest that these parietal regions are capable of integrating sensory cues from multiple sensory modalities in order to program the subsequent deployment of visual attention. Expand
Auditory-somatosensory multisensory processing in auditory association cortex: an fMRI study.
It is demonstrated that auditory and somatosensory inputs converge in a subregion of human auditory cortex along the superior temporal gyrus, and the multisensory region identified in the present investigation may be the human homologue of CM. Expand
Activation Timecourse of Ventral Visual Stream Object-recognition Areas: High Density Electrical Mapping of Perceptual Closure Processes
Scalp-current density mapping of the Ncl revealed bilateral occipito-temporal scalp foci, which are consistent with generators in the human ventral visual stream, and specifically the lateral-occipital or LO complex as defined by hemodynamic studies of object recognition. Expand
