The task included three conditions: neutral, congruent, and incongruent. Participants consisted of 15 healthy adults and 15 patients with poststroke aphasia. Compared to healthy adults, aphasic patients showed significantly longer reaction times and reduced accuracy across all conditions, with a more pronounced interference effect in the incongruent condition. fNIRS analysis revealed distinct neurophysiological differences: decreased activation in Broca's area, increased activation in the ventromedial frontal pole, and atypical recruitment of the left dorsolateral prefrontal cortex (DLPFC) during Stroop interference tasks. These findings highlight the differing neural mechanisms underlying cognitive interference in poststroke aphasia. The integration of fNIRS with the Stroop task enhances our understanding of intentional inhibition deficits and the impact of cognitive interference in aphasic patients. Importantly, these results suggest that deficits in cognitive control and abnormalities in prefrontal regions, such as the frontal pole and DLPFC, may be potential targets for noninvasive neuromodulation to improve cognitive control in poststroke aphasia. The observed atypical activation patterns in these regions underscore their critical role in managing cognitive interference and intentional inhibition. Noninvasive brain modulation techniques may offer promising strategies for modulating these neural mechanisms.

The stroke patients underwent a 4-week AOT. To assess the differences in brain region activity between the patients before and after treatment and the HCs, regional homogeneity (ReHo), and degree centrality (DC) were calculated based on fMRI data separately. Important brain regions were selected as regions of interest (ROIs) for subsequent FC analysis, and finally, comparisons were made to evaluate the therapeutic effects. &lt;b&gt;Results:&lt;/b&gt; Comparing stroke patients before treatment with HCs, the ReHo values were relatively higher in the inferior temporal gyrus, median cingulate, and paracingulate gyri, and relatively lower in the calcarine fissure and surrounding cortex, middle occipital gyrus, and paracentral lobule. The DC values were relatively higher in the cerebellum, middle frontal gyrus, inferior temporal gyrus, inferior frontal gyrus, orbital part, middle frontal gyrus, and supramarginal gyrus, and relatively lower in the cuneus and paracentral lobule. The FC between the parahippocampal gyrus and the superior parietal gyrus was relatively high, and the FC between the superior occipital gyrus and the superior parietal gyrus was relatively low. Comparing stroke patients after treatment with HCs, the ReHo values were relatively higher in the caudate nucleus, and relatively lower in the cerebellum, superior frontal gyrus, medial orbital, calcarine fissure and surrounding cortex, and middle temporal gyrus. The DC values were relatively higher in the middle frontal gyrus and superior frontal gyrus, and relatively lower in the temporal pole: superior temporal gyrus, calcarine fissure, and surrounding cortex. The FC between the caudate nucleus and the superior parietal gyrus was relatively high, and the FC between the calcarine fissure and surrounding cortex, middle frontal gyrus, orbital part, and the superior parietal gyrus was relatively low.

However, the underlying mechanisms of poststroke motor dysfunction remain incompletely elucidated. In this study, we employed multifrequency band wavelet transform-based amplitude of low-frequency fluctuations (Wavelet-ALFFs) to investigate the alterations of spontaneous regional neural activity in patients with ABGIS. <b>Methods:</b> A total of 39 ABGIS patients with motor dysfunction and 45 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging. Wavelet-ALFF values were calculated in the conventional frequency band (0.01-0.08 Hz), slow-5 frequency band (0.01-0.027 Hz), and slow-4 frequency band (0.027-0.073 Hz). A two-sample <i>t</i>-test was performed to compare the Wavelet-ALFF values between the two groups with sex as a covariate and Gaussian random field (GRF) theory (voxel <i>p</i> < 0.001, cluster <i>p</i> < 0.05, two-tailed) was used for the multiple corrections. Furthermore, spearman correlation analysis was performed to assess the relationship between alterations in regional neural activity between Fugl-Meyer Assessment (FMA) and National Institutes of Health Stroke Scale (NIHSS) scores. <b>Results:</b> In comparison to HCs, patients with ABGIS showed significantly increased Wavelet-ALFF in the left middle temporal gyrus (MTG) and decreased Wavelet-ALFF in the right inferior frontal operculum (IFO) across all three frequency bands (conventional, slow-4, and slow-5). In the left superior occipital gyrus (SOG), Wavelet-ALFF was decreased in the conventional frequency band but increased in the slow-4 frequency band. Additionally, patients with ABGIS demonstrated reduced Wavelet-ALFF in the right superior temporal gyrus (STG) in the conventional and slow-4 frequency bands. In the slow-5 frequency band, increased Wavelet-ALFF was observed in the left calcarine cortex (CC), left middle frontal gyrus (MFG), left supramarginal gyrus (SMG), and left postcentral gyrus (PCG), while decreased Wavelet-ALFF was noted in the right precuneus (PCu). Correlation analysis revealed that increased Wavelet-ALFF in the left CC in the slow-5 frequency band was positively correlated with the FMA score. No other correlations were detected in the conventional and slow-4 frequency bands. <b>Conclusions:</b> The altered spontaneous neural activity was frequency-specific in patients with ABGIS, and the slow-5 frequency band exhibited better results.

The neural mechanisms underlying ADHD remain inadequately understood, and current approaches do not well link neural networks and attention networks within brain networks. Our objective is to investigate the neural mechanisms related to attention and explore neuroimaging biological tags that can be generalized within the attention networks. In this paper, we utilized resting-state functional magnetic resonance imaging data to examine the differential functional connectivity network between ADHD and typically developing individuals. We employed a graph convolutional neural network model to identify individuals with ADHD. After classification, we visualized brain regions with significant contributions to the classification results. Our results suggest that the frontal, temporal, parietal, and cerebellar regions are likely the primary areas of dysfunction in individuals with ADHD. We also explored the relationship between regions of interest and attention networks, as well as the connection between crucial nodes and the distribution of positively and negatively correlated connections. This analysis allowed us to pinpoint the most discriminative brain regions, including the right orbitofrontal gyrus, the left rectus gyrus and bilateral insula, the right inferior temporal gyrus and bilateral transverse temporal gyrus in the temporal region, and the lingual gyrus of the occipital lobe, multiple regions of the basal ganglia and the upper cerebellum.
