Summary: Classical analyses of neural activity usually average power over trials, while recent studies have shown that beta band activity occurs in transient bursts. In this study, we demonstrate that burst shapes vary widely and are predicted by variability in synaptic drives. Burst detection algorithm and principal component analysis were then used to identify different waveform motifs and their contribution to movement-related beta dynamics. This suggests that sensorimotor beta bursts are not homogeneous events and reflect distinct computational processes.

Summary: Resting-state functional magnetic resonance imaging (fMRI) is widely used for understanding brain networks and behavior. Idiosyncratic patterns in resting-state connectivity can predict individual differences, and these patterns may also persist during task-based fMRI. This study compared different methods for analyzing task-based fMRI data and found that both low-pass filtering and general linear model residuals are suitable for measuring background connectivity.

Summary: This study examines the relationship between stress response, intrinsic amygdala connectivity, and memory performance. The findings suggest that stress response is associated with changes in connectivity and affects the valence of remembered emotional content.

Summary: The study reveals age-related changes in the navigation network organization, with increasing modularity under resting-state and increasing flexibility under task-state. Task-modulated FC changes were found to be greater in adults than in children, suggesting differences in network organization between age groups during tasks.

Summary: This study assessed the effect of nitrous oxide on brain function for treatment-resistant depression (TRD) using event-related potential (ERP) components and functional connectivity networks (FCNs) methods. The results showed that nitrous oxide improved depressive symptoms better than placebo, with significant differences found in ERP components and increased brain functional connectivity after nitrous oxide treatment. These findings suggest that nitrous oxide improves depression symptoms for TRD by modifying brain function.

Summary: The study investigates the relationship between brain structure and function using microstructural MRI and resting-state MEG data. The shortest-path-length algorithm is found to be better at predicting functional connectivity patterns, with streamline count and myelination leading to the highest correlations between predicted and observed functional connectivity.

Summary: The study investigated the co-activation patterns of the whole brain in various tasks and found robust antagonistic interactions between networks. The findings suggest that anti-correlations are a biologically meaningful phenomenon and may reflect an important principle of functional brain organization.

Summary: Resting-state functional connectivity provides insights into brain network organization, but the functional importance of task-related changes remains unclear. Task-state functional connectivity can predict cognitive task activations better, driven by individual-specific functional connectivity patterns. These findings suggest task-related changes play a role in reshaping brain network organization and altering neural activity flow during task performance.

Summary: The study investigated the reliability of brain graphs extracted from resting state EEG data before and after submaximal exercise in male participants. Results showed good to excellent ICC values for brain graphs extracted after exercise in theta, alpha-1 and alpha-2, beta-1 and beta-2 frequency bands. Exercise had a positive effect on the reliability of wPLI-based measures, but a negative effect on the reliability of Coh-based graph measures.

Summary: This study investigated changes in resting-state functional connectivity and sensorimotor behavior in a simulated spaceflight environment with elevated ambient CO2 during strict 6 degrees head-down tilt bed rest. Significant changes were found in functional connectivity between vestibular, visual, somatosensory, and motor brain areas under the HDBR+CO2 condition, with post-HDBR+CO2 FC changes significantly associated with alterations in sensorimotor performance. The findings suggest that these connectivity changes reflect multisensory reweighting associated with adaptation to the HDBR+CO2 microgravity analog environment.

Summary: This study utilized advanced regression and predictive modeling techniques to demonstrate that learning-related functional connectivity alterations across the whole brain can predict individual habit strength. The functional connectivity changes involving the sensorimotor network and the cingulo-opercular network play a pivotal role in predicting individual habit strength.

Summary: Optically-pumped magnetometers (OPMs) have the potential to improve data quality and wearability in magnetoencephalography (MEG), with results showing high similarity to state-of-the-art cryogenic MEG systems. This indicates the potential for OPMs to ultimately replace traditional sensors for MEG measurements.

Summary: This study investigated the impact of motor imagery-based training (MI) on corticospinal excitability, finding that engaging in MI in 4-minute blocks may be more effective in generating and maintaining corticospinal excitability compared to 2-minute and 6-minute blocks. The findings provide physiological evidence to optimize the structure of MI training sessions for better effectiveness.

Summary: A multidisciplinary team in Canada developed consensus recommendations for the use of rTMS as an adjunct intervention for upper extremity motor recovery in stroke rehabilitation clinical trials. Through a comprehensive evidence review and consensus meeting, recommendations were made for target poststroke population, rehabilitation intervention, outcome measures, and specific rTMS parameters. This marks a significant step towards the translation of noninvasive brain stimulation technologies for stroke recovery.
