Summary: The study found that in a bimodal attention task, the neuronal dynamics between the VAN and DAN mainly occur in the 12-20Hz frequency range, with the suppression of VAN aiding in better task performance. Furthermore, a power decrease and enhanced synchronization in both VAN and DAN were observed when multisensory integration enhanced attention involuntarily.

Summary: This study found that the continuum between autism and schizophrenia traits determines the predictive strategies adopted by individuals in cognitive reasoning. Individuals closer to the schizophrenia pole tend to rely more on prior knowledge in decision-making, while individuals closer to the autism pole tend to rely more on sensory evidence. These findings contribute to the understanding of the pathological mechanisms underlying autism and schizophrenia.

Summary: Functional magnetic resonance imaging (fMRI) was used to investigate the age-related decline in visual search performance. The results showed that age-related effects were observed in frontoparietal regions and were specific to conjunction search. The study also found that the efficiency of search and the influence of salient targets on frontoparietal activation were both affected by age.

Summary: Predictive-coding is a influential theory in Neuroscience, but its falsifiability has been questioned. We propose that there are patterns of behavioral and neuroimaging data that can challenge predictive-coding. Furthermore, we argue that the precision-weighting in predictive-coding can explain contra (vanilla) predictive patterns, but this does not render predictive-coding unfalsifiable.

Summary: This study identified deficits in attention processing in prolactinoma patients, with larger frontoparietal theta and alpha coherence compared to healthy controls. The positive correlation between frontoparietal coherence and altered prolactin levels suggests the significance of prolactin for adaptive brain compensation in prolactinomas. The coherence between frontal and parietal regions may serve as a possible electrophysiological biomarker for detecting deficient attention processing in prolactinomas.

Summary: The study suggests that transcranial direct current stimulation (tDCS) can enhance transfer effects on working memory (WM), especially in individuals with high WM capacity. However, in individuals with low WM capacity, tDCS may reduce transfer effects on WM. This highlights the importance of adjusting tDCS protocols based on individual differences in WM capacity.

Summary: Visual attention is affected by past experiences, and expectations about distractor locations can be learned and reduced through statistical learning. Using magnetoencephalography (MEG), it was found that early visual cortex showed reduced neural excitability at retinotopic locations associated with higher distractor probabilities. This suggests that proactive mechanisms of attention are involved in predictive distractor suppression and are associated with altered neural excitability in early visual cortex.

Summary: Research suggests that inhibition of distracting information relies heavily on expectations derived from past experience, and both distractor feature and location regularities contribute to distractor suppression. While observers are sensitive to regularities across longer time scales, the observed effects largely reflect intertrial repetition.

Summary: When identifying an object in a rapid serial visual presentation (RSVP) stream, observers often make errors by reporting a distractor instead of the target. Two experiments examined whether these errors are associated with the speed of attentional engagement. The results showed that distractor intrusions are closely linked to the timing of selective attention allocation, making the intrusion paradigm a valuable tool for studying the temporal dynamics of attention.

Summary: This study found that both older and younger adults were able to encode targets paired with distractors, and the level of alpha power modulation during encoding predicted recognition success. Older adults showed signs of higher distractibility, but this did not harm their episodic memory for target information. The research also demonstrated that older adults only modulated alpha power during high distraction, indicating that both age groups can successfully employ inhibitory control mechanisms but older adults fail to do so when distraction is minimal.

Summary: Sustained attention affects perception in a discrete, rhythmic way, with modulations of decoding performance by frequency-specific top-down brain activity, suggesting a potential link between attentional sampling rate and visual stimulus representation modulations in the brain, particularly in the frontoparietal attention network. However, the behavioral relevance of these effects remains to be established.

Summary: This study aimed to identify the white matter tracts that mediate the effect of methylphenidate (MPH) on ADHD patients. The results showed that the anterior thalamic radiation (ATR), superior longitudinal fasciculus (parietal endings) (SLFp), and superior longitudinal fasciculus (temporal endings) (SLFt) were significantly associated with the effects of MPH. In addition, ADHD symptom severity was related to lower fractional anisotropy (FA) within the ATR, and individuals with higher FA in SLFp compared to SLFt exhibited stronger behavioral effects of MPH and beta power modulation.

Summary: We analyzed EEG and fMRI data and found that beta and alpha oscillations are related to laminar-specific fMRI connectivity, while gamma oscillations are not. The decrease in beta power is associated with an increase in deep-to-deep layer coupling between brain regions and an increase in deep/middle-to-superficial layer connectivity within brain regions. On the other hand, the decrease in alpha power is related to reduced connectivity between deep and superficial layers within brain regions. These findings suggest that different frequency bands are involved in different feedback-related neural processes in laminar-specific fMRI-based connectivity.

Summary: Although the neural mechanism of methylphenidate's effect on selective attention in children with ADHD remains unclear, this study found that first-dose methylphenidate led to improvements in behavioral performance and increased amplitude of certain electrophysiological indexes associated with selective attention. The enhanced N2pc and P3 amplitudes were related to faster behavioral response speed in children with ADHD. Additionally, lower individual P3 amplitude was associated with more severe inattention symptoms and weaker methylphenidate effect on N2pc amplitude.

Summary: Emotional cues can enhance attention and information processing. Electrophysiological brain research suggests that increased gamma band activity and decreased alpha band activity over posterior brain areas are associated with attention allocation. This study investigated whether the modulation of brain oscillations occurs in a stimulus-induced manner or leads to prolonged state-like changes. The results showed decreased alpha and increased gamma power in response to unpleasant pictures compared to pleasant pictures, supporting a stimulus-induced effect of alpha and gamma power. The findings also suggest event-related attention toward unpleasant pictures and are discussed in relation to previous EEG research and behavioral research on threat-induced freezing-like response.

Summary: We conducted a study to investigate the role of brain oscillations in coordinating the oculomotor and visual system during rapid processing in reading. Using MEG and eye-tracking data, we found that the onsets of eye movements were synchronous with the phase of alpha oscillations, particularly for low frequency words. Source modelling revealed that these alpha oscillations originated from the right-visual motor cortex (BA 7). Our findings suggest that alpha oscillations help to time the processing between the oculomotor and visual systems during natural reading, with a greater effect observed for challenging words.

Summary: Growing evidence suggests that travelling waves are functionally relevant for cognitive operations in the brain. In this study, the researchers examined the perceptual alpha-echo, which propagates as a travelling wave across the cortical surface. They found that the amplitude of the alpha-echo decayed with respect to the sensor distance, and the propagation latencies consistently increased with distance. These findings contribute to the understanding of cognitive processes in the brain.

Summary: Previous research has suggested that retrospective attention on working memory (WM) can have two potential benefits: target strengthening and non-target inhibition. However, it is not clear which hypothesis contributes to the improved WM performance, and the neural mechanisms underlying this attentional benefit remain unknown. In this study, we recorded electroencephalography (EEG) signals while participants performed a retrospective-cue WM task, and found that only representations of target features were enhanced by valid retrospective attention, supporting the target strengthening hypothesis. Further analysis revealed that certain brain signals and components were modulated by valid retrospective attention and correlated with individual differences and moment-to-moment fluctuations in behavioral outcomes, suggesting the influence of attentional preparatory processes on goal-directed behavior. These findings provide neurophysiological evidence for the benefits of retrospective attention in improving WM precision, and highlight the important role of the frontoparietal attentional network in controlling WM representations.

Summary: The relationship between conscious experience and brain activity has been a subject of interest for scientists and philosophers for centuries. In order to advance the research on consciousness, an adversarial collaboration was established between proponents of two major theories in the field. Two experiments were designed to test the contrasting predictions of these theories and provide decisive evidence in favor or against them. The study will involve six independent laboratories and use three complementary methods to obtain data.

Summary: A study found that distracting inputs can be actively suppressed through spatial cues, nonspatial cues, or experience, which are controlled by multiple top-down mechanisms of attention. However, the neural mechanisms underlying the proactive suppression of distracting inputs guided by spatial distractor cues are still unknown. The study recorded electroencephalography signals from 110 participants to investigate the role of alpha activity in proactive distractor suppression induced by spatial cues and its influence on subsequent distractor inhibition.

Summary: Food deprivation can lead to neurological dysfunctions, including memory impairment. This study used Aplysia as an animal model to investigate the memory deficits caused by prolonged food deprivation. The results showed that 14 days of food deprivation decreased the level of 5-HT in the hemolymph, which contributed to the lack of sensitization and its cellular correlates. However, exogenous application of 5-HT partially induced sensitization in the food deprived animals.
