Neuromagnetic Correlates of Sensorimotor Synchronization.
July 1, 2000... Abstract * Sensorimotor synchronization tasks, in which subjects have to tap their finger in synchrony with an isochronous auditory click, typically reveal a synchronization error with the tap preceding the click by about 20 to 50 msec....

Syntactic Gender and Semantic Expectancy: ERPs Reveal Early Autonomy and Late Interaction.
July 1, 2000... Abstract * This experiment explored the effect of semantic expectancy on the processing of grammatical gender, and vice versa, in German using event-related-potentials (ERPs). Subjects were presented with correct sentences and sentences...

Modulation of Spatial Orientation Processing by Mental Imagery Instructions: A MEG Study of Representational Momentum.
July 1, 2000... Abstract Under appropriate conditions, an observer's memory for the final position of an abruptly halted moving object is distorted in the direction of the represented motion. This phenomenon is called "representational momentum" (RM). We...

Auditory and Visual Spatial Localization Deficits Following Bilateral Parietal Lobe Lesions in a Patient with Balint's Syndrome.
July 1, 2000... Abstract * Lesion and electrophysiological studies indicate that the parieral lobes play a role in visual spatial attention and in computing the spatial coordinates of visual input. Fewer studies have investigated the role of the parietal...

Models of the Posterior Parietal Cortex Which Perform Multimodal Integration and Represent Space in Several Coordinate Frames.
July 1, 2000... Abstract * Many neurons in the posterior-parietal cortex (PPC) have saccadic responses to visual and auditory targets. The responses are modulated by eye position and head position. These findings suggest that PPC integrates multisensory...

Activation Timecourse of Ventral Visual Stream Object-recognition Areas: High Density Electrical Mapping of Perceptual Closure Processes.
July 1, 2000... Abstract * Object recognition is achieved even in circumstances when only partial information is available to the observer. Perceptual closure processes are essential in enabling such recognitions to occur, We presented successively less...

Brain Activation During Reading in Deep Dyslexia: An MEG Study.
July 1, 2000... Abstract * Magnetoencephalographic (MEG) changes in cortical activity were studied in a chronic Finnish-speaking deep dyslexic patient during single-word and sentence reading. It has been hypothesized that in deep dyslexia, written word...

Electrophysiological Correlates of Phonological Processing: A Cross-linguistic Study.
July 1, 2000... Abstract * It is well known that speech perception is deeply affected by the phoneme categories of the native language. Recent studies have found that phonotactics, i.e., constraints on the cooccurrence of phonemes within words, also have...

Volitional Covert Orienting to a Peripheral Cue Does Not Suppress Cue-induced Inhibition of Return.
July 1, 2000... Abstract * Detection reaction time (RT) at an extrafoveal location can be increased by noninformative precues presented at that location or ipsilaterally to it. This cue-induced inhibition is called inhibition of return or ipsilateral...

Electrophysiological Evidence for the Modulation of Retrieval Orientation by Depth of Study Processing.
July 1, 2000... Abstract * Event-related potentials (ERPs) were employed to investigate whether brain activity elicited by retrieval cues in a memory test varies according to the encoding task undertaken at study. Two recognition memory test blocks were...

The Role of Segmentation in Phonological Processing: An fMRI Investigation.
July 1, 2000... Abstract * Phonological processes map sound information onto higher levels of language processing and provide the mechanisms by which verbal information can be temporarily stored in working memory. Despite a strong convergence of data...

Tickling Expectations: Neural Processing in Anticipation of a Sensory Stimulus.
July 1, 2000... Abstract * Predictions of the near future can optimize the accuracy and speed of sensory processing as well as of behavioral responses. Previous experience and contextual cues are essential elements in the generation of a subjective...

Meeting Report: Transcranial Magnetic Stimulation and Studies of Human Cognition.
July 1, 2000... * A James S. McDonnell Foundation workshop [1] examined the role of TMS in studies of human cognition. A summary of the workshop presentations, discussion, and the recommendations appear below. [2] A selected reference list is provided at the...
