A separable convolutional neural network-based fast recognition method for AR-P300

Frontiers in Human Neuroscience, 2022
Augmented reality-based brain–computer interface (AR–BCI) has a low signal-to-noise ratio (SNR) and high real-time requirements. Classical machine learning algorithms that improve the recognition accuracy through multiple averaging significantly affect ...

When "It" becomes "Mine": attentional biases triggered by object ownership. [PDF]

, 2011
Previous research has demonstrated that higher-order cog- nitive processes associated with the allocation of selective atten- tion are engaged when highly familiar self-relevant items are encountered, such as oneðs name, face, personal possessions and ...

The Construction of Large-Scale Cortical Networks for P300 From Scalp EEG

IEEE Access, 2018
Multiple studies, which studied cortical generators and cerebral networks of P300 based on electroencephalogram (EEG) and functional magnetic resonance imaging, have investigated the possible mechanism underlying the inter-subject variability of P300 ...

You do the math: coding of bets and outcomes in a gambling task in the feedback-related negativity and p300 in healthy adults. [PDF]

PLoS ONE, 2013
The feedback-related negativity (FRN) is an event-related potential (ERP) component associated with processing of performance feedback, with more negative amplitudes for losses relative to wins. The amplitude of the FRN following near misses, i.e.

The relationship between Hippocampal asymmetry and working memory processing in combat-related PTSD: a monozygotic twin study [PDF]

, 2012
BACKGROUND: PTSD is associated with reduction in hippocampal volume and abnormalities in hippocampal function. Hippocampal asymmetry has received less attention, but potentially could indicate lateralised differences in vulnerability to trauma.

Evidence for mental ability related individual differences in the attentional blink obtained by an analysis of the P300 component [PDF]

, 2012
Attentional blink (AB) refers to impaired identification of a target (T2) when this target follows a preceding target (T1) after about 150-450 ms within a stream of rapidly presented stimuli. Previous research on a possible relation between AB and mental

The emotional facial recognition performance of Chinese patients with schizophrenia: An event-related potentials study

Indian Journal of Psychiatry, 2023
Background: Patients with schizophrenia have deficits in identifying and recognizing emotional facial expressions. Aim: This study aimed to explore the event-related potential (ERP) responses of patients with schizophrenia (SZ) and healthy controls (HC ...
