“…providing more ATP) in right PFC with positive benefits for the WM-related FPN network. An alternative explanation is that the neurovascular coupling between hemodynamic activities and EEG plays a role in visual information processing 30, 31 . Thus, further EEG-fNIRS/fMRI studies are necessary to gain a better understanding of the underlying mechanism of beneficial effects from tPBM.…”

Transcranial photobiomodulation (tPBM) is a novel and noninvasive intervention, which has shown promise for improving cognitive performances. Whether tPBM can modulate brain activity and thereby enhance working memory (WM) capacity in humans remains unclear. In this study, we delivered double-blind and sham-control tPBM with different wavelengths to the prefrontal cortex (PFC) in 90 healthy participants and conducted four electroencephalography (EEG) experiments to investigate whether individual visual working memory capacity and related neural response could be modulated. We found that 1064 nm tPBM applied to the right PFC has both a substantial impact on visual working memory capacity and occipitoparietal contralateral delay activity (CDA), no matter orientation or color feature of the memorized objects. Importantly, the CDA set-size effect during the retention mediated the effect between 1064 nm tPBM and subsequent WM performance. However, these behavioral benefits and the corresponding changes of CDA set-size effect were absent with tPBM at 852 nm wavelength or with the stimulation on the left PFC. Our findings provide converging evidence that 1064 nm tPBM applied on the right PFC can improve visual working memory capacity, as well as explain the individual's electrophysiologyical changes about behavioral benefits.

“…Additionally, we observed that contralateral alpha power following feedback was predictive of N2pc amplitudes on the upcoming choice, suggesting that it could be related to subsequent attentional orienting to the next stimulus location. Specifically, preparatory activity in the sensory cortices is thought to facilitate subsequent attentional processing, as it is correlated with subsequent N2pc amplitudes relative to the attended location (Zhao et al, 2019), but also with decreased RTs (van den Berg et al, 2016). Multivariate pattern analyses also recently showed that preparatory contralateral alpha power boosts stimulus processing (Barne et al, 2020).…”

“…The N2pc is a lateralized component that is larger on contralateral electrode sites of the attended location, and that shows larger amplitudes if the attended target is associated with reward (Kiss et al, 2009). In addition, N2pc amplitudes are predicted by preparatory alpha oscillations during attentional selection tasks, and are accompanied by alpha oscillations relative to the choice that was made (Zhao et al, 2019, Bacigalupo & Luck, 2019. Thus, the N2pc reflects a neural correlate of attentional processing in space.…”

Learned feature-based stimulus-reward-associations can modulate behavior and the underlying neural processing of information. In our study, we investigated the neurocognitive mechanisms underlying learning of spatial stimulus-reward-associations. Participants performed a probabilistic spatial reward-learning task that required participants, within 40 trials, to learn which out of four locations on a computer screen yielded the most gain-feedback when chosen. Our behavioral findings show that participants learned to choose which location was most rewarding. Those findings were paralleled by significant amplitude differences in event-related potentials (ERPs) elicited by the presentation of loss and gain feedback; the amplitude of the feedback-related negativity (FRN) was more negative in response to loss feedback compared to gain feedback, but showed no modulation by trial-number. On the other hand, the late positive component (LPC), became larger in response to losses as the learning-set progressed, but smaller in response to gains. Additionally, immediately following feedback presentation, brain activity in the visual cortex - read out through alpha frequency oscillations measured over occipital sites - was predictive of the amplitude of the N2pc ERP component, a marker of spatial attention orienting, observed on the next trial. Taken together, we elucidated neurocognitive dynamics underlying feedback processing in spatial reward learning, and the subsequent effects that spatial stimulus-reward association learning have on spatial attention.

Recognizing Hazard Perception in a Visual Blind Area Based on EEG Features

Many potential hazards are encountered during daily driving in mixed traffic situations, and the anticipatory activity of a driver to a hazard is one of the key factors in many crashes. In a previous study using eye-tracking data, it was reliably recognized whether the eyes of a driver had become fixated or pursued hazard cues. A limitation of using eye-tracking data is that it cannot be identified whether the anticipatory activity of a driver to hazards has been activated. This study aimed to propose a method to recognize whether the psychological anticipation of a driver had been activated by a hazard cue using electroencephalogram (EEG) signals as input. Thirty-six drivers participated in a simulated driving task designed according to a standard psychological anticipatory study paradigm. Power spectral density (PSD) features were extracted from raw EEG data, and feature dimensions were reduced by principal component analysis (PCA). The results showed that when a driver detected a hazard cue, the alpha band immediately decreased, and the beta band increased approximately 300 ms after the cue appeared. Based on performance evaluation of the support vector machine (SVM), k-nearest neighbor (KNN) method, and linear discriminant analysis (LDA), SVM could detect the anticipatory activity of the driver to a potential hazard in a timely manner with an accuracy of 81%. The findings demonstrated that the hazard anticipatory activity of a driver could be recognized with EEG data as input.
