Abstract Recent studies proposed a general psychopathology factor underlying common comorbidities among psychiatric disorders. However, its neurobiological mechanisms and generalizability remain elusive. In this study, we used large longitudinal neuroimaging cohort from adolescence to young adulthood (IMAGEN) define neuropsychopathological (NP) across externalizing internalizing symptoms using multitask connectomes. We demonstrate that NP might represent unified, genetically determined, delayed development of the prefrontal cortex further leads poor executive function. also show be reproducible in multiple developmental periods, preadolescence early adulthood, generalizable resting-state connectome clinical samples (the ADHD-200 Sample STRATIFY & ESTRA Project). conclusion, identify neural basis mental health disorders, bridging multidimensional evidence behavioral, genetic substrates. These findings may help develop new therapeutic interventions for comorbidities.

Abstract Schizophrenia is a prototypical network disorder with widespread brain-morphological alterations, yet it remains unclear whether these distributed alterations robustly reflect the underlying layout. We tested large-scale structural in schizophrenia relate to normative and functional connectome architecture, systematically evaluated robustness generalizability of network-level alterations. Leveraging anatomical MRI scans from 2439 adults 2867 healthy controls 26 ENIGMA sites data Human Connectome Project ( n = 207), we against two susceptibility models: (i) hub vulnerability, which examines associations between regional centrality magnitude disease-related alterations; (ii) epicenter mapping, identifies regions whose typical connectivity profile most closely resembles morphological To assess specificity, contextualized influence site, disease stages, individual clinical factors compared that found affective disorders. Our findings show schizophrenia-related cortical thinning spatially associated hubs, suggesting highly interconnected are more vulnerable Predominantly temporo-paralimbic frontal emerged as epicenters profiles linked schizophrenia’s alteration patterns. Findings were robust across sites, related symptoms. Moreover, transdiagnostic comparisons revealed overlapping bipolar, but not major depressive disorder, suggestive pathophysiological continuity within schizophrenia-bipolar-spectrum.

Functional connectivity (FC), or the statistical interdependence of blood-oxygen dependent level (BOLD) signals between brain regions using fMRI, has emerged as a widely used tool for probing functional abnormalities in clinical populations due to promise approach across conceptual, technical, and practical levels. With an already vast steadily accumulating neuroimaging literature on neurodevelopmental, psychiatric, neurological diseases disorders which FC is primary measure, we aim here provide high-level synthesis major concepts that have arisen from findings manner cuts different conditions sheds light overarching principles. We highlight allowed us discover ubiquity intrinsic networks virtually all brains clarify typical patterns neurodevelopment over lifespan.

Alzheimer's and Parkinson's diseases are the most prevalent neurodegenerative disorders. Their etiologies idiopathic, treatments symptomatic orientated towards cognitive or motor deficits. Neuropathologically, both proteinopathies with pathological aggregates (plaques of amyloid-β peptide neurofibrillary tangles tau protein in disease, Lewy bodies mostly composed α-synuclein disease). These deposits appear nervous system a predictable accumulative sequence six neuropathological stages. Both disorders present long prodromal period, characterized by preclinical signs including hyposmia. Interestingly, olfactory system, particularly anterior nucleus, is initially preferentially affected pathology. Cerebral atrophy revealed magnetic resonance imaging must be complemented histological analyses to ascertain whether neuronal and/or glial loss neuropil remodeling responsible for volumetric changes.

Abstract Giulio Tononi's integrated information theory (IIT) proposes explaining consciousness by directly identifying it with information. We examine the construct validity of IIT's measure consciousness, phi (Φ), analyzing its formal properties, relation to key aspects and co-variation relevant empirical circumstances. Our analysis shows that identification causal efficacy which differentiated networks accomplish global transfer (which is what Φ in fact measures) mistaken. This misidentification has consequence requiring attribution a range natural systems artifacts include, but are not limited to, large-scale electrical power grids, gene-regulation networks, some electronic circuit boards, social networks. Instead treating this as disconfirmation, IIT embraces it. By regarding these bearers ex hypothesi , led toward orbit panpsychist ideation. departure from science we know can be avoided recognizing functional misattribution at heart identity claim. show, for example, function actually performed, least human case, cortical combination differentiation integration identifies consciousness.
