Summary: This study examines whether Redundancy Gain (RG) can be dissociated from the response stage of a go/nogo paradigm and whether the meaningfulness of a stimulus affects the interhemispheric transfer stage. Experiment 1 uses a lateralized match-to-category paradigm with categories of varying meaningfulness. Experiment 2 introduces a novel design that separates the perceptual stage from response formation. The results indicate that redundancy gain occurs earlier for highly meaningful stimuli during stimulus identification. Experiment 2 supports the hypothesis that redundancy gain arises from interhemispheric integration of perceptual information, rather than response formation.

Summary: The structure of the brain's connectome has a significant impact on information transfer efficiency, with a trade-off between inner hemispheric and interhemispheric connectivity. Certain brain regions, such as the cingulate cortex and frontal areas, play a key role in this phenomenon. The connectivity conservation phenomenon observed in the study may explain the functional, behavioral, and cognitive variability among different brains.

Summary: Bilateral cochlear implants (BiCIs) have been shown to improve speech intelligibility and sound localization abilities in individuals with severe to profound hearing loss, but many BiCI users do not benefit from binaural hearing to the same extent as normal hearing listeners. This study aimed to investigate the potential benefits of BiCIs for speech intelligibility and listening effort using pupillometry, and found that although speech intelligibility was similar between the Better Ear condition and the Bilateral condition, participants showed larger pupil dilation in the Bilateral condition, indicating increased effort. The results suggest that the BiCI users in this study did not demonstrate binaural redundancy and did not experience a release from effort when listening with two ears, possibly due to poor integration of asymmetric inputs.

Summary: The study found similar hemispheric asymmetric deficits in individuals with schizophrenia and those at genetic high risk for schizophrenia, which are associated with schizophrenia-related risk genes. Further bioinformatics enrichment analysis revealed that these risk genes may be involved in signal transduction, neural development, and neuron structure.

Summary: The heritability and genetic correlation of homologous left and right white matter connections were found to be similar and coupled between hemispheres, with varying degrees of overlap in genetic factors across the human brain. Subcortical white matter connections showed stronger heritability and higher chance of complete overlap in genetic factors compared to cortical connections. Long-range connections exhibited stronger heritability and interhemispheric genetic correlations than short-range connections. These findings illuminate the genetics underlying white matter connectivity and its interhemispheric relationships in the human brain.

Summary: Frontal EEG alpha band asymmetries, specifically left hemispheric activation, were found to be stronger under stress compared to a non-stressful control condition. This result supports the asymmetric inhibition model and the capability model of emotional regulation, suggesting that frontal asymmetries during emotional challenge are more pronounced than during rest.

Summary: This study investigated the differences in callosal transfer speed of verbal and nonverbal stimuli in university students. The results showed that slow readers have slower right-to-left transfer speed at the parietal site related to visual word decoding process, similar to individuals with reading disorders. The difference was not observed with nonverbal stimuli, suggesting that it originates at the orthographic visual lexical level rather than at earlier basic visual processing.

Summary: This review article provides an integrated overview of existing research findings on amygdala asymmetries. The study finds that hemispheric asymmetries in the amygdala exist in terms of both function and structure, and these asymmetries are influenced by temporal characteristics, emotional valence, and perceptual properties. Furthermore, the article highlights the alterations of amygdala asymmetries reported in different patient groups, contributing to a deeper understanding of atypical amygdala asymmetries.

Summary: This study investigates the inter-hemispheric transport of trace gases in the atmosphere, focusing on contributions from the Northern Hemisphere extratropics, Southern Hemisphere extratropics, and tropics to the upper troposphere and lower stratosphere. The results show that the transport from the Northern Hemisphere extratropics to the UTLS is stronger than from other regions, with significant seasonal variability. The asymmetry of inter-hemispheric transport is mainly driven by the Asian summer monsoon and an interplay between the monsoon and westerly ducts triggers cross-Equator transport in the UTLS.

Summary: Speech prosody provides important clues about the speaker's communicative intentions. This study used high-density electroencephalography (EEG) to investigate the neurophysiological basis of intonation and speech act understanding, finding that prosodic features are reflected at the neurophysiological level. The results demonstrate that humans can rapidly detect and understand speaker intentions in linguistic interactions through neurophysiological indexes when pragmatic and lexico-semantic information are fully expressed.

Summary: This study investigated whether the late positive potential (LPP), a neural marker of attention and stimulus processing, could predict the response to cognitive-behavioral therapy (CBT) in patients with obsessive-compulsive disorder (OCD). The results showed that higher LPP responses to negative stimuli were predictive of lower self-reported OCD symptoms after completion of CBT. The findings suggest that patients with increased emotional reactivity may benefit more from CBT, possibly through reduced avoidance of anxiety-provoking stimuli. The LPP shows promise as a prognostic marker for CBT response in OCD, but further research is needed.

Summary: The study found that indirect replies were less certain, less predictable, less coherent with and less semantically similar to their context question compared to direct replies. These effects were smaller when direct and indirect replies were matched for the type of speech acts for which they were used. All measured cognitive dimensions were strongly associated with each other.

Summary: This study found that physical distancing measures during the coronavirus pandemic can lead to increased psychological distress, especially in individuals with pre-existing mental disorders. Factors such as low social resources, empathic disconnection, and perceived social isolation were found to contribute to higher levels of distress in this population. These findings provide valuable information for targeted social interventions to prevent an increase in incidence of mental disorders during physical distancing measures.

Summary: Human behavior often consists of repeated action sequences that become automatic or habitual through extensive repetition. However, we are also required to react flexibly and in a goal-directed manner in response to events in our environment. In this study, we developed a novel behavioral paradigm to investigate how implicitly learned action sequences interfere with goal-directed control.

Summary: The study found that hypoactivation in the right inferior frontal gyrus during inhibition is specifically related to substance-related problems in individuals with SUDs. Interestingly, increased activity in the same region may serve as a resilience factor in substance use without SUDs. Future research should differentiate between processes linked to the degree of substance use and substance-related problems to better understand why some substance users develop SUDs while others do not.

Summary: Craving, induced by substance-related cues, plays a crucial role in continued substance use and relapse. Regulation of craving (ROC) is essential for successful treatment, and engaging with the risks of drug use (reappraisal) may be more beneficial than avoiding craving triggers (distraction). However, these effects do not seem to be mediated by lasting changes in cue-related motivated attention (LPP).

Summary: This article discusses how neuroimaging research can reveal the neural predictors of relapse in substance use disorders and how interventions can modify these markers. The study found that brain activity related to drug value and automatized use behaviors can predict relapse. Established and emerging interventions can help treat substance use disorders by modifying brain activity associated with drug value. However, executive deficits in addiction may affect the effectiveness of interventions targeting control-related brain areas.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
