N400 is een negatieve golf in het elektro-encefalogram (EEG) die op ongeveer 400 msec optreedt na het begin van een semantisch deviant woord. Dit is een woord dat qua betekenis afwijkt van de strekking van een zin waarin dit woord is ingebed. De N400 is een component van de ERP waaraan zeer veel publicaties zijn gewijd.

Test material consisted of neutral or affect-laden sentences presented visually. EEG signals were recorded from 7 … Nevertheless, the functional significance of both the N400 and the P600, in terms of the underlying cognitive processes, is still a topic of hot debate (e.g., Shen et al and Ito et al). In this context, [6] have shown, that a semantic P600 paradigm source localized to executive rather than classical language areas, thus supporting an extra-linguistic rather than an intra-linguistic N400. P600. 2. What kind of ERP is likely to be observed in response to this sentence?

Each of these is named for whether the wave points up (P for positive) or down (N for negative), and how long it takes for the wave to crest. Emilia – Courtesy of parent. plots difference between classifier performances (P600-N400 decoding accuracy) to identify time points where one classifier performed better than the other (below 0% for N400 better than P600 and above 0% P600 better than N400) and masked for significance (p<0.05 [thin lines] and p<0.01 [thick lines], FDR corrected) Applied to the N400/P600 pattern, this was e.g. suggested by Curran, Tucker, Kutas and Posner (1993), who interpreted the biphasic pattern of negativity and positivity as a latency shifted positive-going ERP that appears first in the semantically congruous and then later in the incongruous condition. N400 is usually seen in a response to unexpected lexical items, so semantic processing. P600 is usually associated with syntactic processing, like ungrammaticality and garden path sentences.

Still later components of the ERP (i.e., N400 or P600) involve cognitive functions that have to do with the processing of language and syntax, as well as memory. There is a substantial literature of some 370 papers showing that various ERP components are altered in either amplitude or latency in AD patients, and that ERPs could thus be used as diagnostic markers of the disease.

All three studies argue for the existence of individual differences in adults’ native-language processing, the ramifications of which have not yet been made clear. 1.2. Invasive EEG Sentence processing Word association N400 P600 ABSTRACT The e ﬀect of word association on sentence processing is still a matter of debate. Some studies observe no e ect while others found a dependency on sentence congruity or an independent eﬀect.

The N400 is a component of time-locked EEG signals known as event-related potentials (ERP). It is a negative-going deflection that peaks around 400 milliseconds post-stimulus onset, although it can extend from 250-500 ms, and is typically maximal over centro-parietal electrode sites. ERP markers of native language processing The N400 and P600 are among the most studied electrophysiolo- gical signatures of native language comprehension. The N400 is a negative deﬂection peaking around 400 ms after stimulus onset that indexes the processing of meaning. How to evaluate N170, N200, P300, N400 and P600 from EEG signals ?

N400; P600; ERP 1. Introduction The capacity to combine the meanings of individual EEG to address this question, in combination with an experimental paradigm that is similar to the one used in previous MEG research on phrasal composition. Experimental MEG and EEG data remain a valuable the negativity called N400 (Kutas & Hillyard, 1980), have in the literature typically been associated with semantic violations in sentences. Another electrophysiological response, the positive P600 waveform, has mostly been associated with syntactic and morphological violations. However, recently, the P600 has been reported also in Still later components of the ERP (i.e., N400 or P600) involve cognitive functions that have to do with the processing of language and syntax, as well as memory. There is a substantial literature of some 370 papers showing that various ERP components are altered in either amplitude or latency in AD patients, and that ERPs could thus be used as diagnostic markers of the disease. Notably, EEG measurements revealed clear distinct N400 and P600 responses to both prototypical and ambiguous items between the three groups at anterior, central, and posterior scalp sites.
