Abstract Verbal interaction and imitation are essential for language learning development in young children. However, it is unclear how mother–child dyads synchronize oscillatory neural activity at the cortical level turn-based speech interactions. Our study investigated interbrain synchrony pairs during a turn-taking paradigm of verbal imitation. A dual-MEG (magnetoencephalography) setup was used to measure brain from interactive simultaneously. Interpersonal synchronization compared between socially noninteractive tasks (passive listening pure tones). Interbrain networks showed increased conditions theta alpha bands. Enhanced interpersonal observed right angular gyrus, triangular, left opercular parts inferior frontal gyrus. Moreover, these parietal regions appear be hubs exhibiting high number connections. These areas could serve as marker component social communication. The present first investigate interactions using setup. results advance our understanding suggest role “gating” learning.

Causal evidence for a coordinated temporal interplay within the language network

Proceedings of the National Academy of Sciences, Год журнала: 2023, Номер 120(47)

Опубликована: Ноя. 14, 2023

Recent neurobiological models on language suggest that auditory sentence comprehension is supported by a coordinated temporal interplay within left-dominant brain network, including the posterior inferior frontal gyrus (pIFG), superior and sulcus (pSTG/STS), angular (AG). Here, we probed timing causal relevance of between these regions means concurrent transcranial magnetic stimulation electroencephalography (TMS-EEG). Our TMS-EEG experiments reveal region- time-specific evidence for bidirectional information flow from left pSTG/STS to pIFG back during processing. Adapting condition-and-perturb approach, our findings further can be AG in state-dependent manner.

Neural network localization in Parkinson’s disease with impulse control disorders

Frontiers in Aging Neuroscience, Год журнала: 2025, Номер 17

There is a huge heterogeneity of magnetic resonance imaging findings in Parkinson's disease (PD) with impulse control disorders (ICDs) studies. Here, we hypothesized that brain regions identified by structural and functional studies PD ICDs could be reconciled common network. In this study, an initial systematic literature review was conducted to collect evaluate whole-brain related ICDs. We subsequently utilized the Human Connectome Project (HCP) dataset (n = 1,093) novel connectivity network mapping (FCNM) technique identify affected A total 19 25 contrasts, incorporating 345 individuals ICDs, 787 without were included analysis. By using HCP FCNM technique, ultimately aberrant neural networks predominantly involve default mode (middle inferior temporal gyrus, anterior cingulate cortex, angular gyrus) subcortical (caudate nucleus). This study suggests heterogeneous neuroimaging can attributed shared abnormalities networks. These dysfunctions are associated impaired self-regulation, decision-making, heightened impulsivity Our integrate diverse results from previous studies, providing clearer understanding neurobiological mechanisms underlying at level.

Background Type 2 diabetes mellitus (T2DM) has been demonstrated an increased risk factor of cognitive impairment or even dementia. Kinds resting-state functional magnetic resonance imaging indices have proposed and used to investigate the brain mechanism underlying diabetic impairment. This study aimed explore early changes in spontaneous neural activity among T2DM patients without by means multiple rs-fMRI indices. Methods age-, sex-, education matched control subjects were included this study. Three indices, namely amplitude low-frequency fluctuation (ALFF), regional homogeneity (ReHo) voxel-mirrored homotopic connectivity (VMHC) computed after image pre-processing. The Montreal Cognitive Assessment (MoCA) was performed distinguish normal cognition. Brain volume also evaluated. Correlation analyses conducted any relationship clinical characteristics. Results detected significantly decreased right angular left prefrontal gyrus including middle superior frontal gyrus. Increased activities observed caudate supplementary motor area. No correlation between characteristics survived comparison correction. But we a significant, but ALFF ReHo values reported areas. Conclusion combination ALFF, VMHC abnormal regions which These results may enhance our understanding at stage.

Frequency-specific directed connectivity between the hippocampus and parietal cortex during verbal and spatial episodic memory: an intracranial EEG replication

Cerebral Cortex, Год журнала: 2024, Номер 34(7)

Опубликована: Июль 1, 2024

Abstract Hippocampus-parietal cortex circuits are thought to play a crucial role in memory and attention, but their neural basis remains poorly understood. We employed intracranial electroencephalography (iEEG) investigate the neurophysiological underpinning of these across three tasks spanning verbal spatial domains. uncovered consistent pattern higher causal directed connectivity from hippocampus both lateral parietal (supramarginal angular gyrus) medial (posterior cingulate cortex) delta–theta band during encoding recall. This was independent activation or suppression states cortex. Crucially, supramarginal gyrus enhanced participants with recall, highlighting its behavioral significance. Our findings align attention-to-memory model, which posits that attention directs cognitive resources toward pertinent information formation. The robustness results demonstrated through Bayesian replication analysis recall periods tasks. study sheds light on casual signaling within hippocampus–parietal circuits, broadening our understanding critical roles human cognition.

Altered angular gyrus activation during the digit symbol substitution test in people living with HIV: beyond information processing speed deficits

Scientific Reports, Год журнала: 2025, Номер 15(1)

Speed-of-information processing (SIP) is often impaired in people living with HIV (PLWH), typically assessed through tests such as the digit symbol (DS) and search, which also rely on motor executive functions. This study aims to disentangle SIP deficits from other cognitive impairments PLWH using an MRI-adapted substitution test (mDSST). Fifty-seven (34.7 ± 11.2 years) 50 age-matched without (PLWoH, 31.8 9.9 completed standardized neuropsychological mDSST. Behavioral performances brain activations were compared, correlations drawn between group-differentiating clinical ratings of domains. Results showed that performed worse DS made fewer responses, was slower mDSST, correlating ratings. Notably, greater attention compared PLWoH, rather than or motor. exhibited primary cortex activation reduced right angular gyrus activation. These findings suggest SIP-related may be partially linked abnormal visuospatial attention, reflected by activation, higher potentially serving a compensatory mechanism. Future studies should explore whether prefrontal regions implicated are more severely affected PLWH.
