Neural networks are successfully used to imitate and model cognitive processes. However, provide clues about the neurobiological mechanisms enabling human cognition, these models need mimic structure function of real brains. Brain-constrained differ from classic neural by implementing brain similarities at different scales, ranging micro- mesoscopic levels neuronal function, local links circuit interaction large-scale anatomical between-area connectivity. This review shows how brain-constrained can be applied study in silico formation for symbol concept processing work towards explanations specifically abilities.

Theories of language organization in the brain commonly posit that different regions underlie distinct linguistic mechanisms. However, such theories have been criticized on grounds many neuroimaging studies processing find similar effects across regions. Moreover, condition by region interaction effects, which provide strongest evidence functional differentiation between regions, rarely offered support these theories. Here we address this using lesion-symptom mapping three large, partially-overlapping groups aphasia patients with left hemisphere damage due to stroke (N = 121, N 92, 218). We identified multiple measure associating posterior middle temporal gyrus syntactic comprehension deficits, inferior frontal expressive agrammatism, and angular semantic category word fluency deficits. Our results are inconsistent recent hypotheses network undifferentiated respect high-level processing.

Stroke is one of the most common causes disability, and there are few treatments that can improve recovery after stroke. Therapeutic development has been hindered because a lack understanding precisely how neural circuits affected by stroke, these change to mediate recovery. Indeed, some hypotheses for CNS changes recovery, including remapping, redundancy, diaschisis, date more than century ago. Recent technological advances have enabled interrogation with ever greater temporal spatial resolution. These techniques increasingly being applied across animal models stroke human survivors, shedding light on molecular, structural, functional undergo Here we review studies highlight important mechanisms underlie impairment We begin summarizing knowledge about in activity occur peri-infarct cortex, specifically considering evidence remapping hypothesis Next, describe importance population dynamics, disruptions dynamics allocation neurons into spared restore functionality.

Aging is associated with functional activation changes in domain-specific regions and large-scale brain networks. This preregistered Functional magnetic resonance imaging (fMRI) study investigated these effects within the domain of semantic cognition. Participants completed 1 nonsemantic 2 tasks. We found no age differences core regions. However, right inferior frontal gyrus showed difficulty-related increases both groups. suggests that age-related upregulation this area may be a compensatory response to increased processing demands. At network level, older people more engagement default mode less executive multiple-demand network, aligning people's greater knowledge reserves declines. In contrast, was age-invariant control Finally, adults reduced demand-related modulation task but not These findings provide new perspective on neural basis cognition aging, suggesting preserved function specialized networks help maintain later life.

Brain network dynamics not only endow the brain with flexible coordination for various cognitive processes but also a huge potential of neuroplasticity development, skill learning, and after cerebral injury. Diffusive progressive glioma infiltration triggers functional compensation, which is an outstanding pathophysiological model investigation reorganization underlying neuroplasticity. In this study, we employed dynamic conditional correlation to construct framewise language networks investigated reorganizations in 83 patients left hemispheric gliomas involving (40 without aphasia 43 aphasia). We found that, healthy controls (HCs) patients, resting state clustered into 4 temporal-reoccurring states. Language deficits-severity-dependent topological abnormalities dFCs were observed. Compared HCs, suboptimal observed those aphasia, while more severe disruptions aphasia. Machine learning-based dFC-linguistics prediction analyses showed that states significantly predicted individual patients' scores.

Singing-based treatments of aphasia can improve language outcomes, but the neural benefits group-based singing in are unknown. Here, we set out to determine structural neuroplasticity changes underpinning singing-induced treatment effects chronic aphasia. Twenty-eight patients with at least mild nonfluent poststroke were randomized into two groups that received a 4-month multicomponent intervention (singing group) or standard care (control group). High-resolution T1 images and multishell diffusion-weighted MRI data collected time points (baseline/5 months). Structural gray matter (GM) white (WM) assessed using network region interest-based voxel-based morphometry (VBM) quantitative anisotropy-based connectometry, their associations improved outcomes (Western Aphasia Battery Naming Repetition) evaluated. Connectometry analyses showed group enhanced WM connectivity left arcuate fasciculus (AF) corpus callosum as well frontal aslant tract (FAT), superior longitudinal fasciculus, corticostriatal bilaterally compared control group. Moreover, VBM, GM volume increase inferior cortex (Brodmann area 44) The BA44, AF, FAT correlated naming abilities after intervention.
