Summary: Brain network analysis is an effective method to detect abnormalities in functional interactions for brain disorders like autism spectrum disorder (ASD). Traditional studies focusing on node-centric functional connectivity (nFC) miss valuable information, unlike the edge-centric functional connectivity (eFC) approach proposed in this study. By utilizing co-fluctuations information between brain region edges, our model achieved high performance in classifying ASD using the ABIDE I dataset, with an accuracy of 96.41%, sensitivity of 98.30%, and specificity of 94.25%. These results suggest that eFC can be used to develop a reliable machine-learning framework for diagnosing mental disorders and identifying biomarkers.

Summary: This study used symptom-based clustering to identify subgroups of ASD and found distinct functional connectivity patterns in these subgroups. Participants with mild ASD showed increased connectivity in the beta band, while those with severe ASD exhibited decreased connectivity in the alpha band. Additionally, significant differences in global and regional topological abnormalities were found between the subgroups in both alpha and beta bands.

Summary: Sensorimotor issues in autism spectrum disorder (ASD) involve deficits in multimodal sensory feedback integration and reduced reliance on error-monitoring processes. This study found that individuals with ASD showed reduced functional connectivity in specific brain regions during a visuomotor task at high force levels. Additionally, reduced connectivity was associated with more severe ASD symptoms. These findings suggest that parietal-cerebellar connectivity may serve as a neural marker underlying both core and comorbid features of ASD.

Summary: There is evidence that abnormal interactions between the thalamus and cortex contribute to attention deficits and sensory sensitivities in individuals with autism spectrum disorder (ASD). However, previous functional MRI studies have produced inconsistent findings regarding the direction and location of group differences. The present study used rigorous protocols to minimize the effects of head motion and found that individuals with ASD showed increased connectivity between the thalamus and temporal cortex. Both groups showed age-related decreases in thalamic connectivity with the occipital cortex. These findings suggest that thalamocortical hyperconnectivity in ASD may disrupt attention and contribute to sensory sensitivities.

Summary: This study proposes a temporal dynamics learning (TDL) method for network-based brain disease identification using rs-fMRI time-series data. By integrating network feature extraction and classifier training into a unified framework, it addresses the issues of previous studies paying less attention to the evolution of global network structures over time and treating feature extraction and training as separate tasks.

Summary: Autism spectrum disorder (ASD) is difficult to diagnose, but neuroimaging data can enhance diagnostic results. However, limited time and resources for scanning neuroimages restrict dataset size and weaken result generalization. We propose a deep learning approach combined with the F-score feature selection method for ASD diagnosis using a functional magnetic resonance imaging (fMRI) dataset. The selected fMRI functional connectivity features achieve an average accuracy of 64.53% on intra-site datasets and 70.9% on the whole ABIDE dataset. Network topology analysis shows decreased path length and cluster coefficient in ASD, indicating a loss of small-world architecture to a random network.

Summary: This study found that children with ASD showed significantly reduced resting alpha power compared to typically developing children. Differences in GABA and Glx concentrations in specific brain regions were not associated with inter-individual variation in alpha power within the ASD group, but decreased Glx in the temporal-parietal junction was linked to increased hyper-sensitivity in ASD children.

Summary: Differences in attention functions have been identified as early features distinguishing infants later diagnosed with ASD. The atypical activity of the locus coeruleus-norepinephrine system may contribute to attentional disengagement impairments observed in ASD. Children with ASD showed larger resting pupil size and poorer attentional disengagement compared to TD peers.

Summary: This study found differences in early perceptual processing of auditory stimuli in children with ASD, while no differences were observed in tactile stimuli. However, there were no differences in response to tactile and auditory stimuli in later attentional components between ASD and TD groups. These results suggest that differences in auditory responsivity patterns in children with ASD may be related to perceptual factors.

Summary: EEG microstates were used to investigate differences between children with Autism Spectrum Development (ASD) and typically developing (TD) participants. The study found that the frequency and global explained variance (GEV) of a specific microstate were lower in the ASD group, while the duration of the same microstate was correlated with ASD-related behaviors. In the TD group, the duration of this microstate was also correlated with participant age and overall alpha power. Another microstate showed higher signal strength and GEV in the ASD group, with different topographical patterns between groups.

Summary: A growing body of research suggests that the locus coeruleus-norepinephrine (LC-NE) system functions differently in individuals with autism spectrum disorder (ASD). This study investigated the dynamics of both tonic and phasic indices of LC-NE function in children with ASD and found that they exhibit increased tonic activity and reduced phasic activity compared to typically developing children. These differences may be associated with impairments in attention and arousal regulation in ASD.

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Summary: This study provides morphometric data on the development of the human medullary arcuate nucleus (AN) by examining the brains of preterm and perinatal infants. The results show that AN morphology demonstrates asymmetry and individual variability during the fetal period. The volume and neuronal number of AN increase exponentially with age, while neuronal density decreases exponentially. The AN may undergo neuron death and neuroblasts production after mid-gestation.

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
