Spider Fungi: New species of and in the aerial rhizomorph web-maker guild in Amazonia.

Rhizomorphs are hair- or wire-like melanized structures with structural differentiation analogous to plant roots that help fungi spread over an area and find food resources. Some species of multiple groups of the and the produce different types of rhizomorphs. In the , the structures are largely found in , particularly in the , , and .

Obsessive-compulsive disorder secondary to focal brain lesions: from lesions to networks.

Background: Obsessive-compulsive disorder (OCD) may develop following brain lesions, but lesion distribution and connectivity patterns are unknown.

Methods: OCD-associated lesions, identified from systematic literature search, were traced on common brain space and compared to control lesions (N=608). Topography was analyzed using brain atlases, and lesion location networks computed using normative functional connectivity (N=1000).
