Summary: This study investigated the brain functional differences between individuals with and without anhedonia in major depressive disorder (MDD). The results showed that MDD patients with anhedonia exhibited increased functional connectivity in the bilateral superior frontal gyrus and decreased functional connectivity in the bilateral middle temporal gyrus and inferior parietal lobule compared to healthy controls. These findings suggest neurobiological differences between different subtypes of depression in MDD.

Summary: Using multimodal MRI, this study identified significant cortical thinning in multiple brain regions, including the right precentral gyrus, in ALS patients, along with alterations in white matter microstructure. The findings also indicated a tight coupling between cortical thickness and white matter integrity in the precentral gyrus cluster. Additionally, decreased self-inhibitory influence in the precentral gyrus cluster was observed in ALS patients, suggesting an imbalance in inhibitory and excitatory neurotransmitters in this region.

Summary: This study investigated the pathophysiological mechanisms of freezing of gait (FOG) in patients with Parkinson's disease by analyzing structural and functional connectivity. The results showed that FOG was associated with white matter abnormalities in specific brain regions and impaired interhemispheric brain connectivity, which correlated with the severity of FOG. Integrating structural and functional MRI data can provide new insights into the mechanisms of FOG in PD.

Summary: There is evidence of age-related declines in anatomical connectivity during adulthood, with associated alterations in functional connectivity. However, the relation between these functional alterations and structural reductions is unclear. By targeting the interhemispheric connections between the visual cortices, this study found age-related reductions in white matter integrity and age-related increases in functional interhemispheric lagged coherence differences. White matter integrity in the splenium of the corpus callosum predicted differences in lagged coherence, and this relationship was mediated by age.

Summary: It has been observed that individuals with autism spectrum disorder (ASD) exhibit reduced interhemispheric resting-state functional connectivity (rsFC) between homotopic regions, which may serve as a potential biomarker for ASD. This study focused on children under 10 years old and found decreased homotopic rsFC in specific brain regions of ASD children, suggesting that alterations in interhemispheric connectivity may be an early feature of ASD and could be a useful biomarker across ages. Additionally, while no significant changes in corpus callosum (CC) volume were found in ASD children, there was a negative correlation between anterior CC volumes and homotopic rsFC strengths in certain brain regions.

Summary: This study used functional MRI to explore the changes in voxel-mirrored homotopic connectivity (VMHC) and seed-based functional connectivity (FC) in patients with primary dysmenorrhea (PDM). The results revealed enhanced VMHC in the bilateral orbital part of the superior frontal gyrus and the bilateral middle frontal gyrus in PDM patients compared to healthy controls. Further analysis showed enhanced connectivity between these areas and pain-related brain structures. The hyperconnectivity between the left middle frontal gyrus and the right cingulate gyrus in patients was negatively correlated with the severity of pain. These findings provide a new perspective on the central mechanism of pain in PDM.

Summary: This study found a correlation between abnormal homotopic connectivity and cognitive impairment in anti-NMDAR encephalitis. Patients with anti-NMDAR encephalitis showed a significant decrease in homotopic connectivity compared to healthy controls, particularly in regions such as the cerebellum, para-hippocampal gyrus, insula, precuneus, and middle frontal gyrus. The findings suggest that interhemispheric functional imbalance plays a significant role in the pathophysiology of cognitive dysfunction in this condition.

Summary: The study revealed that individuals with congenital amusia exhibit increased interhemispheric functional connectivity in the posterior part of the default mode network, particularly in the posterior superior temporal gyrus and posterior cingulate cortex, which were negatively correlated with music perception ability. These findings suggest that the immature state of the default mode network may serve as a reliable neural marker for amusia.

Summary: The study found significantly decreased functional connections in the nucleus accumbens and putamen in apathetic PD patients compared to both non-apathetic PD patients and healthy controls. These findings suggest that asymmetric functional connectivity in the mesocorticolimbic and nigrostriatal systems may contribute to the pathophysiological mechanisms of apathy in PD.

Summary: This study aimed to explore the changes in interhemispheric resting-state functional connectivity (FC) in Parkinson's disease (PD) patients with fatigue. The results showed that PD patients with fatigue had decreased connectivity values in the supramarginal gyri (SMG) compared to PD patients without fatigue and healthy controls. Furthermore, the connectivity values in the SMG were negatively correlated with fatigue severity scores. These findings may contribute to the understanding of the neural mechanisms of fatigue in PD.

Summary: This study investigated dynamic interhemispheric structural and functional connectivity in mild traumatic brain injury (mTBI) patients from early subacute to chronic stages within 1 year of injury. The results showed persistent and time-dependent regional specificity in the loss of integrity in the corpus callosum (CC) after mTBI, with impairment spanning multiple segments over time. Additionally, the loss of interhemispheric structural connectivity through the CC corresponded well to regions presenting altered interhemispheric functional connectivity, leading to decreased executive function in mTBI patients.

Summary: This study analyzed the effect of porosity distribution on the heat transfer performance of shell-and-tube thermal energy storage systems. The results showed that increasing porosity gradient improved the melting rate and average heat transfer rate. The average heat transfer rate increased by 21.6% when the porosity gradient increased along the positive y-direction. Increasing porosity gradient along the outer radius direction improved the heat transfer near the heating wall but slowed down the phase change process near the outer wall. The maximum average heat transfer rate was achieved at epsilon = 0.88 + 0.6r.

Summary: Hidden Markov Models (HMMs) are commonly used to analyze neuroimaging data and identify recurring patterns. However, most existing HMMs define states based on activity levels rather than functional connectivity patterns. In this study, we introduced a new HMM that defines states based on full functional connectivity profiles, which outperformed previous methods in accurately identifying connectivity states.
