When two visual targets are presented in a rapid serial visual presentation (RSVP) paradigm, the ability to identify the second target is reduced when it is presented 200-500ms after the initial target. This phenomenon is referred to as the "attentional blink (AB)." Previous behavioral studies have reported aberrant AB in schizophrenia. The underlying cause, however, of the AB deficit in schizo...

We designed a novel assisted closed-loop optimization protocol to improve the efficiency of brain-computer interfaces (BCI) based on steady state visually evoked potentials (SSVEP). In traditional paradigms, the control over the BCI-performance completely depends on the subjects' ability to learn from the given feedback cues. By contrast, in the proposed protocol both the subject and the machin...

Nowadays, everybody knows what a hybrid car is. A hybrid car normally has two engines to enhance energy efficiency and reduce CO2 output. Similarly, a hybrid brain-computer interface (BCI) is composed of two BCIs, or at least one BCI and another system. A hybrid BCI, like any BCI, must fulfill the following four criteria: (i) the device must rely on signals recorded directly from the brain; (ii...

Emotionally arousing stimuli are known to rapidly draw the brain's processing resources, even when they are task-irrelevant. The steady-state visual evoked potential (SSVEP) response, a neural response to a flickering stimulus which effectively allows measurement of the processing resources devoted to that stimulus, has been used to examine this process of attentional shifting. Previous studies...

Emotionally salient cues are detected more readily, remembered better, and evoke greater visual cortical responses compared with neutral stimuli. The current study used concurrent EEG-fMRI recordings to identify large-scale network interactions involved in the amplification of visual cortical activity when viewing aversively conditioned cues. To generate a continuous neural signal from pericalc...

Abstract In this paper, we propose a human-vehicle cooperative driving system. The objectives of research are twofold: (1) providing feasible brain-controlled vehicle (BCV) mode; (2) control mode. For the first aim, through brain-computer interface (BCI), can analyse EEG signal and get intentions driver. second is manifested in BCV combined with obstacle detection assistance. Considering potent...

We have conducted an experiment in which subjects controlled a brain-computer interface (BCI) without being aware that their brainwaves were responsible for events in the scenario. Ten subjects went through a stage of model training in steady state visually evoked potential (SSVEP)-based BCI, followed by three trials of an immersive experience where stars moved as a response to SSVEP classifica...

We tested whether visual cortical sensitivity to external cues in the context of an acute defensive reaction is heightened or attenuated. A strong cardiac defense (fear) response was elicited by presenting an abrupt, loud acoustic stimulus following a 10-min period of quiescence. Electrocortical responses to aversive and neutral pictures following defensive stimulus onset were measured using de...

Steady-state visual evoked potential (SSVEP) is widely used in electroencephalogram (EEG) control, medical detection, cognitive neuroscience, and other fields. However, successful application requires improving the detection performance of SSVEP signal frequency characteristics. Most strategies to enhance signal-to-noise ratio utilize a spatial filter. Here, we propose method for image filterin...
