Summary: In a population of asymptomatic young adults, spinal segment variants are highly prevalent, with associations between different variants such as cervical ribs, thoracolumbar transitional vertebrae, and lumbosacral transitional vertebrae. This suggests the importance of additional imaging and accurate spine enumeration before interventions or surgeries when spinal segment variants are diagnosed.

Summary: Major depressive disorder (MDD) is a common psychiatric disorder. Using resting-state fMRI, a Transformer-Encoder model was proposed to classify MDD and HC based on functional connectivity. The model achieved high classification accuracy and identified brain regions affected by MDD.

Summary: Recent EEG studies have found that analyzing EEG microstates can help differentiate ALS from control groups and detect signal abnormalities in ALS. The properties of microstates, such as coverage, occurrence, duration, and transition probabilities, show differences between ALS and control groups and correlate with functional decline in limbs and cognitive decline. Microstate characteristics also change over the course of the disease and may reflect abnormalities within sensory and higher-order networks. Furthermore, microstate properties can predict symptom progression in those with cognitive impairments.

Summary: This article discusses the application of deep brain stimulation (DBS) in the treatment of movement disorders and psychiatric disorders. The current open-loop approach may limit the effectiveness of DBS, while the emerging closed-loop approach adapts stimulation parameters to disease symptoms and states, potentially paving the way for personalized treatment protocols.

Summary: This study aims to explore whether transcranial alternating current stimulation (tACS)/transcranial direct current stimulation (tDCS) on the right inferior frontal gyrus (IFG) can have beneficial effects on executive function and to evaluate these effects through resting-state brain function changes. The results showed that inhibition and cognitive flexibility (excluding working memory) were significantly enhanced after tACS/tDCS, with no significant behavioral differences between the tACS and tDCS groups. fNIRS studies revealed decreases in functional connectivity (increased neural efficiency) of relevant cortices in the tDCS group.

Summary: This study used Granger Causal analysis to investigate the changes in amygdala-centered effective connectivity network associated with trait anxiety. The results demonstrated the significance of the prefrontal cortex-amygdala-hippocampus neural circuitry in the neurobiological mechanisms underlying trait anxiety.

Summary: Neurotuberculosis is a heterogeneous disease with various imaging appearances, making it a "great mimicker". The diagnosis is challenging and difficult, potentially leading to severe neurological sequelae. Familiarity with the imaging characteristics is essential for accurate diagnosis and prevention of sequelae.

Summary: Independent component analysis (ICA) is widely used in scalp-recorded EEG analysis, but the polarity indeterminacy is a limitation. This study investigated how EEGLAB handles polarity indeterminacy and its relationship with the classification of independent components (ICs). The findings suggest that EEGLAB biases towards positive polarity in decomposing high-quality brain ICs.

Summary: This study investigated the functional interaction in the cerebello-cerebral circuit in patients with idiopathic generalized epilepsy (IGE). The results revealed altered mapping of cerebral motor components to cerebellum and compressed cerebellar gradient between motor and cognition modules in IGE patients. These findings suggest insufficient integration of sensorimotor information processing in patients with IGE.

Summary: This study investigates the role of rich club hubs in processing hierarchically higher structures in stimulus sequences using both functional magnetic resonance imaging (fMRI) and diffusion weighted imaging data. The findings suggest that rich club hubs are more engaged in processing higher level structures and are more central in the structural network.

Summary: In the fall of 2021, the American Society of Neuroradiology (ASNR) Diversity and Inclusion Committee hosted a webinar to discuss bias in artificial intelligence and provided insights on how neuroradiologists can assess health equity-related bias in these tools. They also showcased examples of clinical workflow implementation to demonstrate the impact of artificial intelligence tools on equitable radiologic care.

Summary: This study analyzed the temporal characteristics of CSF-venous fistula visualization on multiphase decubitus CT myelography. The research found that CSF-venous fistulas were better visualized on the early pass, but those that were better visualized on a delayed pass still had partial visibility on the early pass. Some fistulas were only visible on a single pass.

Summary: This study aimed to explore the neurocognitive mechanisms underlying creative problem-solving. The results revealed that the semantic remoteness of connections is associated with brain activity in different frequency bands. Insight solving is related to activity in specific frequency bands in the frontal and temporal clusters.

Summary: This study aimed to assess the relationship between pretreatment CT perfusion (CTP) parameters and Penumbra Salvage Index (PSI). The results showed a positive correlation between cerebral blood volume (CBV) index and PSI. Subgroup analysis of different types of middle cerebral artery (MCA) occlusion also showed similar trends. However, there was no significant trend or correlation between hypoperfusion intensity ratio (HIR) and PSI.

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.
