Spatial localization in target detection based on decoding N2pc component

open access: yesJournal of Neuroscience Methods, 2022
The Gaze-independent BCI system is used to restore communication in patients with eye movement disorders. One available control mechanism is the utilization of spatial attention. However, spatial information is mostly used to simply answer the "True/False" target recognition question and is seldom used to improve the efficiency of target detection ...

Вклад различных пространственных модуляций в управление экзогенным вниманием: исследование методом N2pc

open access: yesРоссийский психологический журнал, 2022
Введение. Механизмы экзогенного внимания, обладая высокой чувствительностью к физическим характеристикам сенсорных сигналов, обеспечивают первичную адаптацию к окружающей среде.

An early parietal ERP component of the frontoparietal system: EDAN≠N2pc [PDF]

open access: yesBrain Research, 2010
Directing spatial attention or manual response selection by means of arrow cues elicits a characteristic sequence of lateralized ERP components. Van Velzen and Eimer (2003) proposed that one of these components, the EDAN (early directing-attention negativity) is not related to the control of spatial attention but is instead an N2pc in disguise, related

Event-related potentials dissociate effects of salience and space in biased competition for visual representation. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Selective visual attention is the process by which the visual system enhances behaviorally relevant stimuli and filters out others.

Express attentional re-engagement but delayed entry into consciousness following invalid spatial cues in visual search. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: In predictive spatial cueing studies, reaction times (RT) are shorter for targets appearing at cued locations (valid trials) than at other locations (invalid trials). An increase in the amplitude of early P1 and/or N1 event-related potential (

Functional imaging reveals working memory and attention interact to produce the attentional blink [PDF]

open access: yes, 2012
Copyright @ 2012 Massachusetts Institute of Technology PressIf two centrally presented visual stimuli occur within approximately half a second of each other, the second target often fails to be reported correctly.

Changes of Attention during Value-Based Reversal Learning Are Tracked by N2pc and Feedback-Related Negativity

open access: yesFrontiers in Human Neuroscience, 2017
Previously learned reward values can have a pronounced impact, behaviorally and neurophysiologically, on the allocation of selective attention. All else constant, stimuli previously associated with a high value gain stronger attentional prioritization ...

Deployment of spatial attention towards locations in memory representations: an EEG study [PDF]

open access: yes, 2013
Recalling information from visual short-term memory (VSTM) involves the same neural mechanisms as attending to an actually perceived scene. In particular, retrieval from VSTM has been associated with orienting of visual attention towards a location ...

Little engagement of attention by salient distractors defined in a different dimension or modality to the visual search target

open access: yesPsychophysiology, Volume 60, Issue 12, December 2023., 2023
Abstract Singleton distractors may inadvertently capture attention, interfering with the task at hand. The underlying neural mechanisms of how we prevent or handle distractor interference remain elusive. Here, we varied the type of salient distractor introduced in a visual search task: the distractor could be defined in the same (shape) dimension as ...

Online home appliance control using EEG-Based brain-computer interfaces [PDF]

open access: yes, 2019
Brain???computer interfaces (BCIs) allow patients with paralysis to control external devices by mental commands. Recent advances in home automation and the Internet of things may extend the horizon of BCI applications into daily living environments at ...
