F02 – Focus Group Neuroimaging and Genetics

Nikolai Axmacher, Dagmar Timmann-Braun, Robert Kumsta

In year 1, the Focus Group Neuroimaging staff will analyze selected existing data sets of FOR 1581, including re-analyses of fMRI data using normalization methods optimized for the cerebellum. They will also coordinate, prepare and optimize the acquisition of human neuroimaging data (rsfMRI and DTI). In years 2–4, meta-analytic approaches will be used to analyze the differential relationship between functional and structural connectivity and extinction learning across subprojects. State-of-the-art analysis procedures for structural and functional connectivity analysis as well as optimized normalization protocols of the cerebellum will be made accessible to all neuroimaging subprojects throughout the entire funding period.

Hypothesis of F02:

  • Functional and structural connectivity of the extinction network allow predicting inter-individual differences in the efficacy of extinction learning across paradigms.
  • Extinction of appetitive and aversive learning relies on partly distinct functional and structural connectivity patterns.
  • The cerebellum shows pronounced functional and structural connectivity with other areas of the extinction network. Connectivity patterns of different cerebellar subregions play specific roles for different aspects of extinction.
  • Functional and structural connectivity of the extinction network is systematically altered in patients with disturbed extinction.
  • Genetic variability predicts inter-individual differences of functional and structural connectivity of
    the extinction network.
