Summary: This study investigated the working memory deficits in individuals with major depressive disorder (MDD) compared to healthy controls. The results showed that MDD participants had prolonged response times and increased activity in certain brain waves, suggesting they may require increased cognitive resources for working memory tasks.

Summary: The trend of cannabis legalization in the US has resulted in an increase in cannabis users, posing risks such as driving under the influence. Therefore, there is a growing need to accurately quantify cannabis intoxication and its effects on cognitive and motor function. EEG provides a non-invasive method to assess neurophysiological biomarkers, enabling the identification of cannabis intoxication characteristics.

Summary: The study aimed to investigate the effects of 36 hours of total sleep deprivation on working memory under different load levels. The results showed that as the load increased, reaction time increased and accuracy decreased. The impairment of working memory due to sleep deprivation was more pronounced in high load conditions.

Summary: This study investigates the neural basis of working memory capacity by exploiting the content dependence of memory materials. The results show that alpha oscillations track memory capacity in a content-specific manner, dependent not only on the number of items but also on their complexity.

Summary: This study investigated visual temporal integration, specifically how multiple stimuli appearing in rapid succession are perceived as a single event. The results showed that both intrinsic and extrinsic factors have an interactive effect on integration performance, with distinct effects on the event-related potential components. This study provides important insights into the neural mechanisms underlying temporal integration and its impact on perception of longer episodic events.

Summary: The effect of excessive video game playing on cognitive function is a new and controversial topic. Studies have found that excessive video game players may show altered behavioral and brain responses in cognitive tasks when compared to non-players.

Summary: This study investigated the effects of temporal expectations on neural responses and subsequent performance during the retention interval of working memory (WM). The results showed that smaller duration variability and predictable experimental tasks led to greater alpha-power attenuation over the left frontal and parietal regions during WM retention. Moreover, there was a positive relationship between alpha-power attenuation in the left posterior parietal regions and the variability difference in the response benefit. Overall, these findings suggest the importance of temporal expectations in WM maintenance.

Summary: Electroencephalography (EEG) is used to understand and evaluate neurotransmission. This study proposes a strategy based on dynamic time warping (DTW) to enhance averaged event-related potentials (ERPs) by adjusting individual trials to the previously calculated average ERP, reducing attenuation in amplitude of ERP components.

Summary: This study found repetition suppression in all age groups and repetition enhancement in adults through event-related potentials. The magnitude of neural repetition effects was positively correlated with individual item recognition performance, indicating common neural mechanisms of memory formation. This highlights the significance of neural repetition effects as an indicator of individual differences in episodic memory encoding across the lifespan.

Summary: Numerous studies have shown that total sleep deprivation (TSD) impairs sustained attention. However, it is still unclear whether TSD affects the processing of visual selective attention. In this study, participants performed a visual search task before and after TSD, and the results revealed a decrease in accuracy and an increase in response time variability after TSD. Further analysis of event-related potentials (ERPs) indicated changes in brain activity after TSD. These findings provide new evidence and insights into the effects of sleep loss on visual attention.

Summary: Successful encoding, maintenance, and retrieval of information in working memory rely on the coordination of multiple brain regions. Trial-to-trial variability in neural activity during working memory tasks represents fluctuations in the engagement of distinct brain networks and cognitive processes. This study identifies three sub-types of trials with different patterns of activation using a data-driven classification method based on community detection, providing evidence that the brain can utilize multiple mechanisms to perform a given task.

Summary: This study investigates whether conflict and adaptive control in working memory (WM) are reflected by the same neural markers as in selective attention tasks. The results suggest that conflict and adaptive control in WM show similarities to those observed in selective attention tasks, as indicated by event-related potentials (ERPs).

Summary: The study aimed to investigate the impact of heartbeat-evoked potentials (HEPs) on mental workload (MWL) classification based on event-related potentials (ERPs). The results showed that HEPs overlapped or interfered with ERPs, leading to a decrease in accuracy of MWL classification.

Summary: Event-related potential studies have shown that selective attention to the valence of affective words can improve early emotional discrimination. Similar effects may occur when attending to specific emotions in facial expressions, leading to enhanced early processing of faces expressing the attended emotion. This study investigated the effects of selective attention on facial affect and found that it can enhance early emotional processing and also revealed a negativity bias in late controlled processing of facial emotions.
