Summary: By using calibrated functional magnetic resonance imaging, this study found that low-frequency fluctuations of cerebral metabolic rate of oxygen (CMRO2) during resting state exhibited organizational properties similar to previous functional and anatomical connectivity studies. Furthermore, voxel-wise CMRO2 connectivity showed spatial patterns consistent with four specific resting-state subnetworks.

Summary: This study aimed to investigate the influence of brain regions on each other in patients with depression and explore the relationship with treatment response. The results showed widespread dysfunction of rsEC in patients with depression, and the connectivity strength was related to baseline depression severity and treatment response. This suggests that functional rsEC may be useful for predicting the effectiveness of antidepressant treatment.

Summary: The study found associations between peripheral inflammation and adolescent brain connectivity, with higher TNF-α levels linked to changes in neural network connections. Associations with IL-6 and CRP were not significant, suggesting that inflammation may have unique effects on brain connectivity during adolescence.

Summary: This study analyzed large-scale resting-state functional magnetic resonance imaging data and identified transitions between sensory, somatomotor, and internal mentation networks in the resting brain. With increasing age, the internal mentation network becomes more prevalent, while sensory and somatomotor networks are more frequently expressed in younger individuals. The findings demonstrate the dynamic patterns of transition between functionally specialized brain states associated with age.

Summary: This study developed a brain parcellation method based on dynamic functional connectivity and created a new functional brain atlas. The atlas can reveal finer functional boundaries that static methods may overlook, and shows good agreement with cytoarchitectonic areas and task activation maps.

Summary: The reliability and robustness of rs-fcMRI depend on minimizing the influence of head motion on brain signals. This study examined the impact of head motion on newborn brain connectivity using a large dataset. The findings revealed that head motion significantly affected connectivity, with specific effects observed in sensory-related and default mode networks. Implementing a motion correction strategy helped reduce the confounding effects of head motion on neonatal rs-fcMRI.

Summary: This study compared the reliability of conventional single-band fMRI and different multiband (MB) fMRI acquisitions with and without in-plane acceleration across multiple scanning sessions. It found that for cortical areas, MB factor 4 without in-plane acceleration had the highest reliability, while for subcortical areas, conventional single-band fMRI was more reliable.

Summary: Recent research supports a fundamental self hypothesis, suggesting that the self is a baseline function of the brain that regulates cognitive processing and behavior. Understanding this hypothesis can help identify the emergence of self-biased behaviors and predict the influence of brain signals at rest on such behaviors.

Summary: The search for an ideal approach to investigate functional connections in the human brain is a challenge for neuroscience. Recent studies have found that using naturalistic stimuli to collect functional connectivity data predicts cognitive and emotional scores more accurately than using resting-state data. Furthermore, activation maps predicted using naturalistic stimuli are better predictors of individual intelligence scores than those predicted using resting-state data.

Summary: Around 50% of stroke patients have deficits in proprioception, but our understanding of the neurological mechanisms behind these deficits is limited. This study used resting-state functional magnetic resonance imaging (fMRI) to investigate changes in functional brain networks associated with proprioception deficits in stroke patients. The results showed reduced connectivity in specific brain regions, including the supplementary motor area and the supramarginal gyrus, in stroke patients compared to healthy controls. Functional connectivity of these regions, as well as the primary somatosensory cortex and the parietal opercular area, was significantly associated with proprioceptive function. The parietal lobe of the lesioned hemisphere was identified as an important node for proprioception after stroke, and evaluating the functional connectivity of this region could help predict recovery. The study also identified potential targets for therapeutic neurostimulation to aid in stroke recovery.

Summary: This study used noninvasive neuroimaging techniques to assess the impact of a drug on brain functional connectivity. The results showed that an appropriate dose of the drug did not alter brain connectivity, while an excess dose of the drug increased functional connectivity in the frontal regions and may cause deficits related to attention or motivation.

Summary: Anxiety symptoms in Parkinson's disease are associated with structural and functional changes in the fear and limbic cortico-striato-thalamocortical circuits. The neuropathology of PD may affect these circuits in different ways, which explains the high prevalence of anxiety and associated symptoms in PD.

Summary: Deep brain stimulation (DBS) is an effective treatment for refractory obsessive-compulsive disorder (OCD) and neuropsychological assessment plays a crucial role in monitoring the cognitive safety of the treatment. This systematic review found variable cognitive outcomes following DBS for OCD, particularly in domains such as attention, memory, and executive functioning. Further research is needed to better understand the cognitive safety and working mechanisms of DBS for OCD.

Summary: The dual syndrome hypothesis in mild cognitive impairment (MCI) in Parkinson's disease distinguishes between frontostriatal and posterior cortical subtypes, and this study found specific changes in resting-state functional connectivity associated with these subtypes. Patients with posterior cortical deficits showed increased functional connectivity within the basal ganglia network, while patients with frontostriatal deficits showed reduced inter-network connectivity compared to healthy controls and patients with normal cognition or a posterior cortical subtype.

Summary: This study retrospectively analyzed adverse events (AEs) of deep brain stimulation (DBS) procedures and found that surgical site infections and wire tethering were the most common AEs. However, major AEs requiring aggressive treatment were rare. A uniform reporting system for surgical and hardware-related AEs in DBS surgery would be useful.

Summary: This study investigates EEG modifications associated with mild cognitive impairment in Parkinson's disease (PD-MCI) subtypes. The results show that patients with a frontostriatal subtype exhibit spectral and functional EEG alterations, while the posterior cortical subtype does not differ significantly from the normal cognition group. This study provides evidence for the dual syndrome hypothesis and highlights the importance of identifying PD-MCI subtypes.

Summary: The study found that a significant proportion of candidates for subthalamic deep brain stimulation (STN-DBS) have Parkinson's disease mild cognitive impairment (PD-MCI), which is associated with cortical and subcortical alterations. Among the PD-MCI subtypes, patients with posterior cortical deficits (PD-PC) had lower global efficiency and worse performance on visuospatial functions, episodic memory, and language, suggesting a higher risk of dementia. There were no significant differences between the PD-MCI subtypes.

Summary: Deep brain stimulation of the subthalamic nucleus in patients with Parkinson's disease may not affect facial emotion recognition 1 year after surgery, according to a study of 59 patients with pre- and postoperative assessments. However, it does not rule out the potential impact of facial emotion recognition on the outcome of the surgery.

Summary: This study aims to provide insight into the challenges and facilitators HD caregivers face and their needs for a remote support program. The study found that caregivers face a paradox between self-care and caring for others, and challenges such as lack of HD awareness, taboo and shame, loneliness, concerns about heredity and children, and coping with HD symptoms. The study also identified facilitators such as social networks, professional support, openness, early communication, and daily structure. The findings will be used to develop a blended and self-management remote support program to empower caregivers.
