Extensive studies have reported significant activation of the cerebellum in reading and reading-related tasks. However, it has remained unclear how contributes to regions cerebrum are related those cerebellum. In this review, by summarizing previous literature, we observe that multiple cerebellar areas engaged vary their contributions reading. Moreover, selectively connected with cerebral same functional specificity. Abnormalities cerebro-cerebellar connection also associated impairments. We thus propose mapping hypothesis, which suggests might another network rather than serving as a neural hub. This maps collaborates its functionally corresponding cerebrum. framework heightens importance provides new insights into relationship between cerebellum, cerebrum, development.

Abstract The cerebellum has increasingly been recognized for its role in diverse functional processes. reciprocally connected cerebello-cerebral system may scaffold both brain size increase and advanced associative abilities, evolving highly coordinately primates. In parallel, modules have undergone reorganization cerebellar lobules crura I-II (the ansiform area across mammals) reported to be specifically expanded humans. Here we manually segmented 63 cerebella (34 primate species; 9 infraorders) 30 (13 8 infraorders). We show that constraints shape the evolution of system. Using phylogenetic generalized least squares, find scales isometrically with cerebral cortex, whereas scale hyper-allometrically versus both. Our analyses evidence primate-general hyperscaling contrast virtually isometric scaling. Crura important cognitive functions an evolutionary context.

The organization of brain functional networks dynamically changes with emotional stimuli, but its relationship to behaviors is still unclear. In the DEAP dataset, we used nested-spectral partition approach identify hierarchical segregation and integration investigated dynamic transitions between connectivity states under different arousal conditions. frontal right posterior parietal regions were dominant for network whereas bilateral temporal, left parietal, occipital responsible flexibility. High behavior was associated stronger more stable state transitions. Crucially, frontal, central, closely related ratings in individuals. Besides, predicted individual performance based on activities. Our results demonstrate that are could be reliable robust indicators arousal.

Research from different sources supports a link between nutrition and neurodevelopment, but evidence is still sparse regarding the relationship posteriori dietary patterns (DPs) cognitive performance in school-aged children. Within Northern Adriatic Cohort II, Friuli Venezia Giulia, Italy, 379 7-year-old children were cross-sectionally evaluated. Dietary identified through principal component factor analysis based on 37 nutrients children's 3-day records. The Wechsler Intelligence Scale of Children (WISC-IV) test provided measures performance, including full-scale intelligence quotient (FSIQ) single index scores. Each DP was related to FSIQ or scores multiple robust linear regression models. We five DPs named "Dairy Products", "Plant-based Foods", "Fats", "Meat Potatoes", "Seafood" (63% variance explained). After adjustment, no significant observed with score; positive associations found Verbal Comprehension Index Perceptual Reasoning Index.

Abstract Age-related cognitive slowing is a prominent precursor of decline. Functional neuroimaging studies found that processing speed associated with activation and coupling among frontal, parietal cerebellar brain networks. However, how the reciprocal influences inter- intra-network mediate age-related decline in remains insufficiently studied. This study examined intra-brain network slowing. We were interested fronto-insular salience (SN), frontoparietal dorsal attention (DAN), (CN) default mode (DMN). Reaction time (RT) functional MRI data from 84 participants (aged 18–75) collected while they performing Arrow Task visual or audial forms. At subject level, effective connectivities (ECs) estimated regression dynamic causal modelling. group structural equation models (SEMs) used to model latent based on age EC mediators. Age was decreased increased inter-network connectivity. The CN exerting influence DAN (CN → EC) mediated, SN suppressed DMN ECs did not seem play significant roles due ageing. Inter-network connectivity contributes seemingly antagonizing indicate task-related automaticity effortful control top-down would promote greater older individuals.

Abstract Declines in processing speed performance occur aging and are a critical marker of functional independence older adults. Studies suggest that Useful Field View (UFOV) training may ameliorate cognitive decline. Despite its efficacy, little is known about the neural correlates this task. Within current study, 233 healthy adults completed UFOV-based task while undergoing magnetic resonance imaging (fMRI). During “stimulus” portion task, participants must identify target center screen location periphery, among distractors. “probe” portion, decide if object periphery were identical to screen. Widespread bilateral whole-brain activation was observed when patterns contrast subtracted from contrast. Conversely, subtraction associated with discrete consisting 13 clusters. Additionally, evaluating variance accuracy, specific subregions identified be for performance. Our data elucidate used both paradigms assessment function.
