Discrepancy between inter-and intra-subject variability in EEG-based motor imagery brain-computer interface Evidence from multiple perspectives

Introduction Inter- and intra-subject variability are caused by the variability of the psychological and neurophysiological factors over time and across subjects. In the application of in Brain-Computer Interfaces (BCI), the existence of inter- and …

Functional Connectivity Profiles of the Default Mode and Visual Networks Reflect Temporal Accumulative Effects of Sustained Naturalistic Emotional Experience

Determining and decoding emotional brain processes under ecologically valid conditions remains a key challenge in affective neuroscience. The current functional Magnetic Resonance Imaging (fMRI) based emotion decoding studies are mainly based on …

Multimodal and hemispheric graph-theoretical brain network predictors of learning efficacy for frontal alpha asymmetry neurofeedback

EEG neurofeedback using frontal alpha asymmetry (FAA) has been widely used for emotion regulation, but its effectiveness is controversial. Studies indicated that individual differences in neurofeedback training can be traced to neuroanatomical and …

Selective and replicable neuroimaging-based indicators of pain discriminability

Neural indicators of pain discriminability have far-reaching theoretical and clinical implications but have been largely overlooked previously. Here, to directly identify the neural basis of pain discriminability, we apply signal detection theory to …

EEG microstate correlates of emotion dynamics and stimulation content during video watching

Introduction EEG microstates have been widely adopted to understand the complex and dynamic-changing process in dynamic brain systems, but how microstates are temporally modulated by emotion dynamics is still unclear. An investigation of EEG …

Cross-Sessions and Cross-Paradigms Analysis for the Problem of Brain-Computer Interface Inefficiency

Brain-Computer Interfaces (BCIs) allow users to make use of brain activity to control external devices directly for rehabilitation and enhancement of human functions. However, the inefficiency problem that a typical BCI system is unable to …

Cognitive Response in Steady State Evoked Potential

Steady State Evoked Potential (SSEP) has been widely used in the clinical sensory diagnosis and brain computer interface. Through rapid repetitive stimulation, the response of SSEP mainly concentrated on primary sensory areas of the brain, and the …

Neural dynamics of closed-loop alpha wave modulation via phase-locked visual feedback

Compared with the conventional self-regulated EEG neurofeedback strategy, a closed-loop feedback strategy can provide a more precise and robust brain wave modulation. By detecting a participant's instantaneous phase of EEG alpha oscillation and …

The Real Time EEG Phase Locked Feedback Control for Alpha Amplitude and Frequency Regulation: An OpenBCI Implementation

The neural oscillation in electroencephalogram (EEG) signals is highly related to people's psychological cognitive ability. In this work, an OpenBCI version of phase-locked feedback control system has been implemented for real time alpha wave …

Removal of eye-blinking artifacts by ICA in cross-modal long-term EEG recording

Independent Component Analysis (ICA) has became the most popular method to remove eye-blinking artifacts from electroencephalogram (EEG) recording. For long term EEG recording, ICA was commonly considered to costing a lot of computation time. …
