Using ERP measures, the present study investigated the neural mechanism of the interaction between trait aggression and neural sensitivity to unpleasant stimuli. Event-related potentials (ERPs) were recorded for pleasant and unpleasant stimuli when subjects were required to categorize the emotion of stimuli. The ERP result showed a significant interaction between aggression and emotion during 4...

To gain insight into the neural basis of visual attention we combined transcranial magnetic stimulation (TMS) and event related potentials (ERP) during a visual search task. Single-pulse TMS over right posterior parietal cortex (rPPC) delayed response times to targets during conjunction search, and this behavioural effect had a direct ERP correlate. The early phase of the N2pc component that re...

Theory of mind, attributing behaviors to mental states, is a cognitive ability central to human social interactions. To investigate the neural substrates of theory of mind reasoning, we recorded human event-related brain potentials (ERP) while participants made judgments about belief and judgments about reality. A late ERP component (peaking around 800 ms post-stimulus) with a left frontal scal...

Event-related potentials (ERPs), are portions of electroencephalographic (EEG) recordings that are both timeand phase-locked to experimental events. ERPs are usually averaged to increase their signal/noise ratio relative to non-phase locked EEG activity, regardless of the fact that response activity in single epochs may vary widely in time course and scalp distribution. This study applies a lin...

Joint independent component analysis (jICA) can be applied within subject for fusion of multi-channel event-related potentials (ERP) and functional magnetic resonance imaging (fMRI), to measure brain function at high spatiotemporal resolution (Mangalathu-Arumana et al., 2012). However, the impact of experimental design choices on jICA performance has not been systematically studied. Here, the s...

OBJECTIVE The aim of this paper was to increase the information transfer in brain-computer interfaces (BCI). Therefore, a multi-signature BCI was developed and investigated. Stimuli were designed to simultaneously evoke transient somatosensory event-related potentials (ERPs) and steady-state somatosensory potentials (SSSEPs) and the ERPs and SSSEPs in isolation. APPROACH Twelve subjects parti...

In the present paper, we propose a Neuroelectromagnetic Ontology Framework (NOF) for mining Event-related Potentials (ERP) patterns as well as the process. The aim for this research is to develop an infrastructure for mining, analysis and sharing the ERP domain ontologies. The outcome of this research is a Neuroelectromagnetic knowledge-based system. The framework has 5 stages: 1) Data pre-proc...

The ability to discern when actions deviate from goals and adjust behavior accordingly is crucial for efforts at self-regulation, including managing one's weight. We examined whether children with obesity differed from controls in response monitoring, an aspect of cognitive control that involves registering one's errors. Participants performed a cognitive interference task, responding to the co...

We present an adaptive filtering method applied to the single sweep event related potentials data. The method is based on time-sequenced version of the typical adaptive signal enhancers. Two different signals are used at the reference input and the results are compared. The evaluation is made using both simulated and real measurement data. It is found that the use of a reference input composed ...

Introduction: An event-related potentials (ERP) study examined semantic and episodic memory effects and variability in the size and distribution of these effects across different labs. In studies using ERPs, some researchers have argued that ERP markers of semantic and episodic memory — the N400 and fN400, respectively — reflect the same neuropsychological response (Voss & Federmeier, 2011). Ot...
