    description: 'Psychophysiological interaction: connectivity with a seed that changes
      with a psychological condition.'
  gppi:

    description: Generalized PPI, which models every condition rather than a single
      contrast.
  seed_based:
    text: seed_based
    description: Correlation between a seed's time series and every other element,
      with no interaction term.
  dcm:

    description: Dynamic causal modelling, which estimates directed influence from
      a generative model.

    description: Granger causality, which infers direction from temporal precedence.
  coherence:
    text: coherence
    description: Frequency-domain coupling between two signals.
  structural_covariance:
    text: structural_covariance
    description: Correlation of a structural measure between regions across participants,
      rather than of a signal within one. The seed and target are regions as in any
      other method here, but the correlation runs over subjects, so there is no time
      series.
  multivariate:
    text: multivariate
    description: 'Pattern-based connectivity: multivoxel or informational connectivity
      between ensembles of voxels rather than between averaged time series.'
