Crus II

Crus secundum lobuli ansiformis

A posterior lobe region involved in social and cognitive processing: connected with mentalizing and executive networks.

Open in the 3D atlas →All regionsParent structure: Cerebellum

Anatomy

  • The lower part of lobule VII; separated from Crus I by the horizontal fissure.

Functions

  • Active during mentalizing (understanding others’ intentions and beliefs) (Van Overwalle et al., 2014).
  • Participation in the executive control and default mode networks.

Clinical

  • Posterior cerebellar involvement in ASD and social-cognitive difficulties is being studied.

In the model

How this structure is defined in the 3D model, and the data source.

SUIT atlas (Diedrichsen et al., 2009) lobule labels; each point of the cerebellar surface was assigned to the nearest lobule just beneath it. Overlap between SUIT and the model’s cerebellum: Dice 0.90.
