..Our results support models of word recognition that assume a continuous accumulation of task-related information from the stimulus, which might be described by Bayesian principles...

..Furthermore, tongue sounds produced activation in more inferior brain areas. Our data suggest that motor areas in the human brain are part of neural systems subserving the early automatic recognition of action-related sounds...

..The interaction of typicality and lexicality can be explained by integration of information from the early form-based system and lexicosemantic processes...

..The left-hemispheric activity focus in the TP task is assumed to indicate the encoding of the picture name, while frontal symmetrical activity in the PT task might indicate the involvement of working memory processes...

....

..Our approach can be applied to any event-related data using single-stimulus presentation, and allows a detailed characterization of the functional role of category-specific activation patterns...

..The findings will be discussed in the general context of putative brain mechanisms of word and object recognition...

..We discuss the implications of these results for the time line of word recognition processes, and emphasise the value of ERRCs in combination with source analysis in psycholinguistic and cognitive brain research...

..N correlated positively with brain activity in left and right middle temporal gyri as well as right inferior frontal gyrus. Thus, our analysis revealed multiple distinct brain areas involved in visual word processing within one data set...

..We suggest that software packages for source estimation should include comprehensive tools for evaluating the performance of different methods...

....

..g., single-trial data) are analyzed. For that purpose, an efficient and practical implementation of this method will be suggested and illustrated with simulations using a realistic head geometry...

..Therefore, when relating wavelet power spectrum topographies to their neuronal generators, MN should be preferred...

..We interpret the findings in the framework of a neurobiological model of language and discuss the possible role of mirror neurons in the premotor cortex in language processing...

..This served two goals, namely (I) to clarify their possible effects as confounds in ERP experiments employing word-stimuli, and (II) to determine the point in time of lexical access in visual word recognition...

..Furthermore, the latency of the MMN (less than approximately 200 msec postdeviance onset) places an upper limit on the stage of neural processing responsible for the illusion...

..These results indicate that semantic representations grounded in the sensory-motor system play a role in the composition of sentence-level meaning, even in the case of idioms...

..A methodological implication of this study is that, in order to obtain early psycholinguistic ERP effects, stimulus variance must be kept to a minimum...

..Activity spreading within circuits determined by between-area conduction delays accounts for comprehension-related regional activation differences in the millisecond range...

....

....

..In languages with rich morphologies, morphemic processing seems to be supported by distinct neural networks, thereby providing evidence for a specific neuronal basis for morphology as part of the cerebral language machinery...

....

..The results are discussed in relation to the continuity illusion and models of duration encoding...

..This rules out a unified "meaning center" in the human brain and supports a dynamic view according to which words are processed by distributed neuronal assemblies with cortical topographies that reflect word semantics...

....

..We suggest that the early word-evoked negativity might represent an index of reorganization of language after stroke and thus an aphasia recovery potential...

....

....

..In line with previous studies, these differences can be related to the areas involved in the conceptual processing of sensory (visual) and action-related information...

..Source estimation indicates that temporal areas, particularly in the left hemisphere, are the primary cortical loci where such stimulus-specific activity increases occurred...

..We suggest that these results indicate activation of distributed neuronal assemblies that function as category-specific memory traces for words and may involve sensorimotor cortical structures for encoding action words...

..In line with modality-specific theories of conceptual memory, our study suggests that conceptual representations are established by the learning-based formation of cell assemblies in sensory-motor areas...

..Sources of slow wave modulation were located in occipital and posterior parietal cortex, with a right-hemispheric dominance...
