Task-Dependent Functional and Effective #Connectivity during Conceptual Processing

Conceptual knowledge is central to cognition. Previous neuroimaging research indicates that conceptual processing involves both modality-specific perceptual-motor areas and multimodal convergence zones. For example, our previous functional magnetic resonance imaging (fMRI) study revealed that both modality-specific and multimodal regions respond to sound and action features of concepts in a task-dependent fashion (Kuhnke P, Kiefer M, …

The oral #microbiome in early #rheumatoid arthritis patients and individuals at risk differs from healthy controls

It has been suggested that rheumatoid arthritis (RA) may originate at the oral mucosa. Our aim was to assess the oral microbiome and the periodontal condition in patients with early rheumatoid arthritis (ERA) and individuals at risk of RA. MethodsThree groups were recruited (50 participants each): (1) ERA patients (2010 ACR/EULAR criteria), (2) at‐risk individuals …
