Summary: This study examines the role of working memory (WM) and episodic memory (EM) in task performance, suggesting that the mechanisms of EM can better explain the phenomenon of Activity Silent WM (ASWM).

Summary: This study found that although neural activity in working memory (WM) can be tracked, observers can maintain access to information despite temporary interruptions of neural patterns. This implies the existence of a silent form of storage in WM.

Summary: How attentional networks influence conscious perception has been studied using magnetoencephalography in humans. The results showed that both nonpredictive and predictive valid cues increased conscious detection, but only predictive cues affected the response criterion and target contrast. Frontoparietal networks were found to be involved in conscious perception following valid predictive cues. Invalid orienting of spatial attention disrupted conscious processing.

Summary: This study found developmental differences in the brain-state dynamics of the frontal-parietal network (FPN) and default mode network (DMN) during working memory. Children showed a preference for inactive brain states and had a lower probability of transitioning from low-to-high demand states compared to adults. The transition probability was also correlated with working memory performance.

Summary: Speech perception in noisy environments can be enhanced by observing facial movements of communication partners. This study investigated the neural mechanisms of audio-visual speech integration using MEG phase-locking analysis. The results showed that both auditory and visual speech signals were phase-locked to specific frequency brain responses in auditory and visual cortex, suggesting entrainment to syllable-rate components. This study provides insights into the cross-modal predictive mechanisms during speech perception.

Summary: This study tested whether a modified beamforming method can detect correlated source models in human hippocampal data, and found that incorporating a correlated hippocampal source model significantly improves model evidence, helping to explain why the majority of MEG-reported hippocampal activity has been estimated as unilateral.

Summary: The interaction between the cerebral cortex and the diffusely projecting matrix thalamic nuclei plays a key role in arousal and anesthesia. Using a whole-brain corticothalamic neural mass model based on empirical data, we investigate these processes. The model captures key features of propofol anesthesia, including diminished network integration, lowered state diversity, impaired susceptibility to perturbation, and decreased corticocortical coherence. Selectively stimulating the matrix thalamus reproduces empirical results in macaque and induces wake-like information processing states, demonstrating the role of matrix thalamocortical projections in shaping complex cortical dynamics to support conscious awareness.

Summary: Associative binding is disrupted during post-traumatic amnesia (PTA) following traumatic brain injury (TBI). This disruption is caused by pathological slowing of brain activity, leading to misbinding in working memory. The study found that PTA patients showed abnormalities in working memory function and made more misbinding errors than controls. Slow-wave activity and increased low-frequency power were associated with binding impairment in working memory. Connectivity changes in TBI did not contribute to binding impairment. Overall, these findings highlight the importance of associative binding in memory function and its disruption in PTA following TBI.

Summary: This study analyzed magnetoencephalography (MEG) data to examine the cortical engagement during mental imagery tasks. They found that beta power decrements can be used as markers to map and decode cortical engagement and classify different task types with high accuracy.

Summary: Working memory is still a subject of debate in terms of its cellular mechanisms; Barbosa and colleagues' study challenges the idea proposed by Wolff and colleagues by suggesting that working memory is encoded by sustained action potential firing; while some studies indicate that unconscious working memories can be recalled even without measurable neural activity.

Summary: This study investigated differences in visuospatial processing between children with CP and TD children using MEG and oscillatory analysis methods. Children with CP showed weaker cortical oscillations in the theta and gamma frequency bands, as well as slower response times and worse accuracy. Weak theta and gamma oscillations were associated with greater visuospatial performance deficits in both groups.

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: This study found that MS patients showed a smaller maximum theta power increase in the right hippocampus between 0 and 400 ms compared to healthy subjects, and this increase value correlated negatively with reaction time on the task in MS. The results provide evidence of the influence of hippocampal dysfunction on working memory performance in MS.

Summary: The study investigates the neural mechanisms underlying conscious recognition and finds that recognized images elicit enhanced activation in more brain regions, with specific content activity in both activated and deactivated cortical networks. Additionally, recognition-related category information can be decoded from widespread cortical activity but not subcortical activity.

Summary: This study demonstrates that the non-linear part of brain signals carries individual-specific information, playing a crucial role in differentiation. By using neuronal avalanches to characterize fast dynamics between individuals, and comparing with Pearson's correlation, the study shows that selecting the moments and places where neuronal avalanches spread can improve differentiation.

Summary: The transition to becoming a principal investigator or lab leader can be challenging due to the new managerial and leadership responsibilities. One important aspect is creating a supportive lab environment. This article presents ten rules to guide new PIs in developing a positive and thriving lab atmosphere, created collaboratively by Professor Mark Stokes' students and mentees.

Summary: According to the Bayesian framework, visual perception requires active interpretation of noisy sensory signals in light of prior information. Two studies confirm that serial dependence persists even in variable environments and that within a given observer and context, this behavioral bias is stable from one occasion to the next.
