OBJECTIVE: Electroencephalographic (EEG) waves modulated by context have been identified about 400 ms after presentation of a new semantic stimulus, such as a word or a number, within a prior context. However, it is not known if any component of these waves arises from a common brain system activated by different symbolic forms. METHODS: Multichannel EEG recordings were performed in 10 healthy

Measuring the N400 during naturalistic conversation: an EEG hyperscanning study. August 2018. Conference: Society for the Neurobiology of Lanuage 10th annual meeting. Project: EEG hyperscanning 2013-12-31 · In EEG, N400 effects for picture targets have been observed –, and are not qualitatively or quantitatively very different from word-based responses. While there might be slight topographical differences depending on the stimulus format, there is certainly no reason to assume that the N400 effect is specific to a particular format or sensory modality [4] . While their EEG was measured participants were presented with faces rated as attractive or unattractive, followed by words rated as positive or negative.

2004-06-01 · The N400 is a broad negative wave that peaks in the surface EEG around 400 ms after a semantically incongruous word in a meaningful sentence, such as “I take coffee with cream and dog” (Kutas and Federmeier, 2000). 5.1 A hierarchical normal model: The N400 effect. Event-related potentials (ERPs) allow scientists to observe electrophysiological responses in the brain measured by means of electroencephalography (EEG) that are time-locked to a specific event (i.e., the presentation of the stimuli).

Semantic satiation is characterised by the subjective and temporary loss of meaning after high repetition of a prime word. To study the nature of this effect, previous electroencephalography (EEG) research recorded the N400, an ERP component that is sensitive to violations of semantic context. The N400 is characterised by a relative negativity to words that are unrelated vs. related to the N400 EEG-fMRI IFG Semantic uniﬁcation ABSTRACT Semantic uniﬁcation during sentence comprehension has been associated with amplitude change of the N400 in event-related potential (ERP) studies, and activation in the left inferior frontal gyrus (IFG) in … The EEG analysis identified two ERPs, namely the N300 and the N400, that were elicited during the observation of the final visual scene and are typically related to the on-line semantic processing Data were collected from 34 healthy adults (33 ± 13 years) using a 64-channel EEG system. Visual and auditory sequences were kept as comparable as possible to elicit the N100, P300, and N400 responses. National Center for Biotechnology Information Abstract: N400 is a kind of event-related potential (ERP), which is related to language processing of brain and can be used for the evaluation of clinical psychological diseases.

It is a negative-going deflection that peaks We observed a reliable N400 effect as a consequence of the mismatch. This finding validates the combined use of VR and EEG as a tool to study the standard EEG we also provide the high-density EEG recording (256 channels), as well as event-related potentials recording (P300, Mismatch negativity, N400 is composed from lexical meaning and, to this end, conducts EEG experiments.
