Summary: The study proposed a new approach called SMGC to model the directed and hierarchical features of brain functional network and explore causal relationships. The simulation study and application to real datasets demonstrated that the method can capture the complex hierarchical organization of the brain network.

Summary: This review provides an overview of scale-free dynamics and monofractal analysis in neuroscience research, specifically in functional magnetic resonance imaging (fMRI). It emphasizes the use of the Hurst exponent to measure the complexity and scale-invariance of brain signaling. The article highlights the advantages, challenges, and future directions of fMRI monofractal analysis, aiming to promote its understanding, discussion, and application in the field.

Summary: Measuring the temporal complexity of fMRI can provide insights into how brain activity changes over time. This study examined the spatial distribution of temporal complexity in resting state and task fMRI data from 100 subjects. The findings suggest that there is high spatial similarity between different complexity measures and task-specific complexity. Additionally, certain brain networks exhibit stronger complex behavior, regardless of task engagement.

Summary: This study aimed to examine the dynamic variations in brain network coactivation and deactivation across the adult lifespan using resting-state functional MRI. The results showed that aging was associated with reduced coactivation and deactivation, as well as the emergence and persistence of negative correlation patterns between high-order cognitive networks. Additionally, there was a transition from the attentional network and default mode network coactivation to the attentional network and frontoparietal network coactivation with aging.

Summary: Numerous evidence suggests that Tai Chi Chuan training can improve the quality of life for patients with chronic fatigue syndrome (CFS). The training can improve the weakened causal relationship between the sensorimotor network and default mode network, which may serve as a readout parameter for CFS.

Summary: This study identified aberrant whole-brain dynamic functional connectivity patterns in bipolar disorder patients, showing increased transitions between specific dFC states related to high-level cognitive networks and low-level sensory networks compared to healthy controls. This finding could improve our understanding of the neuropathological mechanism of bipolar disorder.

Summary: This study investigated the heritability of directed functional connections in the brain using the state-space formulation of Granger causality (GC) method. The results showed that the directed connectivity of certain cortico-subcortical circuits is strongly influenced by genetic factors, while other connections are less affected.

Summary: Granger causality analysis (GCA) was used to investigate the directional effective connectivity of the amygdala in migraine patients, revealing altered connectivity patterns related to disease duration. The findings suggest that neurolimbic pain networks contribute to abnormalities in multisensory integration and pain modulation deficits in migraine without aura (MwoA) patients.

Summary: This study found that Parkinson's disease patients have weaker interactions among brain white matter functional networks, which are associated with clinical symptoms. These findings may aid in understanding the neuropathology and progression of Parkinson's disease from the perspective of brain white matter function.

Summary: This study aimed to explore the relationship between the disrupted IPL subsystems and hand dysfunction following chronic stroke. By comparing patients with stroke and healthy controls, it was found that the IPL subsystems in stroke patients exhibited abnormalities and were associated with hand performance. Specific reorganizations of IPL subsystems were associated with hand dysfunction following chronic stroke.

Summary: Complex network theory, along with metrics for detecting causality relationships from time series, has been increasingly used to study delay propagation in air transport. To convert landing events into time series, most previous works have focused on fixed-size windows. However, we demonstrate that an optimal airport-specific window size can be calculated to maximize the number of detected causality relationships. We also show that this choice affects the macro-scale structure and airport centrality, highlighting its importance in delay propagation.

Summary: The traditional approaches to measuring depression after traumatic brain injury (TBI) have limitations. This study adopted a symptom-oriented approach and found that post-TBI depression is highly heterogeneous. Different depressive symptoms have distinct associations with personal, injury-related, treatment, and outcome factors.

Summary: Despite rapid social changes in Hong Kong, marriage remains a strong protective factor against suicide for both men and women, particularly among younger individuals. Increasing suicide rates among divorced/separated, never-married, or widowed individuals suggest a need for more psychosocial support.

Summary: This study found that the experience of losing at least one night of sleep was associated with an increased risk of postpartum psychosis in women with bipolar disorder. Sleep quality in late pregnancy was not associated with postpartum psychosis, and perinatal sleep disruption was not associated with postpartum depression.

Summary: This study systematically reviewed the association between psychological pain and suicidality in patients with major depressive disorder (MDD). The results showed that psychological pain was a risk factor for suicidality in MDD patients, especially for those of advancing age. Reducing psychological pain in MDD patients is important for preventing suicidality.

Summary: This study examined the relationship among family accommodation (FA), posttraumatic stress symptoms (PTSS), and functional impairment. The results showed that FA was significantly associated with PTSS and functional impairment. Baseline FA partially mediated the relationship between baseline PTSS and functional impairment. Changes in FA from pre- to post-treatment were associated with relevant outcome variables at post-treatment and 12-month follow-up.
