Language influences cognitive and conceptual processing, but the mechanisms through which such causal effects are realized in the human brain remain unknown. Here, we use a brain-constrained deep neural network model of category formation and symbol learning and analyze the emergent model's internal mechanisms at the neural circuit level. In one set of simulations, the network was presented with similar patterns of neural activity indexing instances of objects and actions belonging to the same categories. Biologically realistic Hebbian learning led to the formation of instance-specific neurons distributed across multiple areas of the network, and, in addition, to cell assembly circuits …

UNLABELLED: Purpose/Objective Research: This study examined combinations of disease outcomes (i.e., walking, cognition, and symptoms) as correlates of physical activity subgroups (insufficiently active vs. sufficiently active) in persons with multiple sclerosis (MS).

RESEARCH METHOD/DESIGN: This study included 213 participants who completed walking and cognitive function tests and self-report measures of symptoms and physical activity. Multivariate analysis of variance and discriminant function analysis identified combinations of MS outcomes associated with physical activity.

RESULTS: The sample had a mean age of 49.6 years (

CONCLUSION/IMPLICATIONS: The findings identified walking endurance and limitations, processing speed, depression, and fatigue as primary correlates of physical …

BACKGROUND: There are now clinically available automated MRI analysis software programs that compare brain volumes of patients to a normative sample and provide

OBJECTIVE: To address this gap in the literature, we examined Neuroreader

METHODS: lvPPA or aMCI patients who underwent MRI with Neuroreader

RESULTS: Cohen's Kappa coefficients were significant in 10 of the 28 computations (

CONCLUSION: Overall, our results indicated moderate to low interrater reliability, and raters never agreed that left asymmetry was present. While lower
