A brain-computer interface (BCI) based on electroencephalography (EEG) is a promising technology for enhancing virtual reality (VR) applications-in particular, gaming. We focus the so-called P300-BCI, stable and accurate BCI paradigm relying recognition of positive event-related potential (ERP) occurring in EEG about 300 ms post-stimulation. implemented basic version such displayed an ordinary ...

The reinforcement learning model (Holroyd and Coles, 2002) argues that a feedback ERN is generated when the feedback is worse than expected. In the current experiment, we investigated whether the reinforcement learning system was also activated by unexpected feedback in a task in which feedback was not necessary to perform properly. A flankers task, in which false negative feedback was presente...

Results from event-related potential (ERP) studies are reviewed that investigated crossmodal links in spatial attention between vision, audition and touch to find out which stages in the processing of sensory stimuli are affected by such crossmodal links. ERPs were recorded in response to visual, auditory, and tactile stimuli under conditions where attention was directed to a specific location ...

Neuroimaging evidence suggests that older adults exhibit deficits in frontally-mediated strategic retrieval processes, such as post-retrieval monitoring. Behavioral research suggests that explicitly directing attention toward source features during encoding may improve source memory for both young and older adults and alleviate age-related source memory impairments, in part, by reducing demands...

Statistical or sequential learning (SL) involves comprehending environmental patterns in which some items precede other items with a given likelihood. SL is thought to occur without attention or consciousness (or explicit knowledge) of the learned patterns and thus is sometimes considered to be implicit learning. However, this assumption is still debatable (Daltrozzo & Conway, 2014). We examine...

In recent years there has been an increased focus on improving the capability and flexibility of organisational information systems through improving, and where necessary, reengineering inter and intra-organisational information flows. In doing so, many firms have realised that the cornerstone of their information systems capability is dependent upon core systems such as Enterprise Resource Pla...

BACKGROUND The vein of Marshall (VOM) is an attractive target during ablation of atrial fibrillation due to its autonomic innervation, its location anterior to the left pulmonary veins and drainage in the coronary sinus. METHODS AND RESULTS We studied 17 dogs. A coronary sinus venogram showed a VOM in 13, which was successfully cannulated with an angioplasty wire and balloon. In 5 dogs, elect...
