Summary: This study found that patients with schizophrenia showed reduced intersensory attention effects for unisensory stimuli compared to healthy controls, but not for bisensory stimuli. At the neural level, schizophrenia patients exhibited decreased intersensory attention effects for bisensory stimuli. However, there were no significant differences between schizophrenia patients and healthy controls in terms of multisensory integration.

Summary: Research has found that meaning maps can predict eye movement patterns more effectively than physical saliency in natural scene viewing. This suggests that the brain rapidly extracts the spatial distribution of semantically informative scene regions. This study used representational similarity analysis to demonstrate the link between physical saliency, semantic informativeness, and neural responses.

Summary: Proactive cognition brain models are widely used and acknowledged nowadays. This study aimed to investigate the similarities and differences in the preparatory activity of selective attention and perceptual expectation. EEG data showed that both manipulations led to a significant prediction of the relevant or expected target category. However, the neural patterns were unique to each condition, indicating distinct mechanisms in attention and expectation. These findings contribute to our understanding of top-down anticipatory processing in the brain.

Summary: Decades of research on top-down control of attention have shown that the lateral frontal cortex plays a key role in facilitating attention to external inputs. However, the specific involvement of the frontal cortex in directing attention externally versus internally remains poorly understood. This study used electrocorticography to investigate this issue, finding that the frontal cortex showed enhanced target effects during external attention compared to internal attention, while both frontal and temporal cortices showed target effects regardless of attention states.

Summary: The Bereitschaftspotential (BP) is a scalp potential that increases slowly over the fronto-central regions as action execution approaches. This study used TMS evoked-potentials (TEP) to stimulate the supplementary motor area (SMA) and found that the reactivity of the left SMA was greater when approaching the peak of BP. Additionally, the effective connectivity of the left SMA increased with the left occipital areas and decreased with the right inferior frontal gyrus, indicating a fast reconfiguration of cortical networks during action preparation.

Summary: Humans have a bias in perceptual judgments, response speed, and discrimination accuracy, but cognitive factors like visual spatial attention can modulate or eliminate this bias. This study used pupillometry and fMRI to investigate the problem and found that the rightward attention control is more effortful than the leftward attention control, and the attention control networks in the right hemisphere may contribute to this asymmetry.

Summary: The representation of spatially separated simultaneous talkers and the modulation of neural representations of attended and unattended speech by talkers' locations and voices in the human auditory cortex are still unclear. This study measured neural responses from patients with implanted electrodes and found that spatial separation between talkers caused preferential encoding of contralateral speech. The location and spectrotemporal features of talkers were encoded in different aspects of neural response.

Summary: Research suggests that images can automatically elicit features of left/right-handed grasp actions in perceptual tasks, and analysis of EEG data indicates that changes in frontal theta power reflect the different correspondence effects evoked by images on left/right key press and reach-and-grasp actions. These findings suggest that cognitive control processes play a crucial role in distinguishing motor features of objects from task-irrelevant features.

Summary: The study examined how different components of event-related potential (ERP) to threat-related facial expressions are modulated by attentional conditions and interindividual differences in trait anxiety. The N170 response to fearful faces was found to increase regardless of perceptual load and spatial attention conditions, while the EPN response to fearful faces only increased during low load and spatial attention to the face. The results question the hypothesis of a general hypersensitivity toward fearful expressions in anxious individuals.

Summary: Top-down predictions based on prior experience help allocate limited attentional resources more efficiently by using mental templates stored in memory. Previous studies have shown increased gamma activity and theta:gamma phase-phase coupling when mental templates meet matching visual stimuli. In this study, researchers investigated how these signatures evolve during the formation of new mental templates and their relation to fidelity. The results showed fidelity-dependent increments of matching-related gamma phase locking and theta:gamma phase coupling over time, with theta:gamma phase synchronization being more important in early learning phases and evoked gamma activity essential for the transition of mental templates into long-term memory.

Summary: Oscillatory theta activity in a fronto-parietal network is associated with working memory processes. Previous research has shown that tACS can alter response times, but the effects are inconsistent across different experiments. This study aims to replicate previous findings and investigate the impact of in-phase tACS with multiple close-by return electrodes on working memory tasks.

Summary: This study investigated the relationship between age and high-frequency oscillations (HFOs), and found that the age effect on HFO rates could not be replicated in scalp-EEG recordings. This lack of replicability may be due to the local propagation patterns of age-related HFOs occurring only in deep structures. Limitations such as small sample size, decreased signal-to-noise ratio compared to invasive recordings, and HFO-mimicking artifacts should be considered.

Summary: Human fluid intelligence is closely related to the ability to solve complex problems, and is associated with a network of multiple-demand regions in the brain. Previous research has shown that individuals with lower fluid intelligence have reduced response to rule-critical events in complex tasks, accompanied by impaired performance. This study used electroencephalography to analyze the early neural dynamics of this process and found that fluid intelligence levels predicted early neural responses around 200-300 ms post stimulus onset.

Summary: Based on prior experiences, we form social expectations and can anticipate other people's responses. In certain conditions, these expectations can lead to illusory perception of non-existent individuals. The activation of the premotor cortex predicts the occurrence of this illusory perception, and its actual appearance is accompanied by activation in sensorimotor and adjacent parietal regions.

Summary: Bilingualism is associated with better cognitive control compared to monolingualism. However, recent debates have questioned the robustness of these findings and the influence of moderators. This study examined the bilingual advantage in cognitive control among language groups immersed in their second language. Results showed that participants immersed in their second language did not exhibit an inhibition advantage in the Stroop task. Additionally, higher script similarity between first and second languages led to faster response times.

Summary: Predicting actions from non-verbal cues and optimising one's response behaviour is crucial in social interactions. This study investigated the neural correlates of cognitive processes during interpersonal predictive coding, revealing dynamic patterns over time. Watching communicative actions led to enhanced coupling in social and mentalising regions, while trying to detect agents in noise dots increased coupling in posterior regions for visual processing. Expected outcomes were modulated by motor system activation, and correctly identifying agents increased activation in visual processing areas. Understanding the temporal dynamics of social interactions and their neural correlates can lead to improved treatment for individuals with social interaction problems.

Summary: A non-invasive brain stimulation study was conducted to investigate the impact of modulating alpha power on the speed of information processing. The results showed that although altering alpha activity may be related to improved cognitive processing, a causal relationship was not established. Instead, it was found that modulating alpha power can influence visuospatial attention orientation but not the speed of information processing.

Summary: The aim of this study was to investigate the potential vulnerability of individuals with seasonal mood fluctuations throughout the year. The researchers compared the behavioral and neurophysiological responses to emotional stimuli in summer between individuals who experience seasonal symptoms in winter and those who do not. They found that EEG power was overall higher in participants without elevated levels of seasonal symptoms, suggesting a difference in emotional processing between the two groups. This study suggests an all-year-long difference in the processing of emotional content in individuals with seasonal symptoms in winter.
