Brain map source

  • I am sharing a brain map from my own research
  • I am requesting a brain map be added from a published article

Map description

Spectral gradients of the cortex describe spatially organized variations in intrinsic oscillatory frequencies across cortical regions, derived from resting-state fMRI data enhanced by a temporal de-correlation (TD) method to improve spectral resolution. These gradients reveal systematic frequency biases: sensory regions (e.g., visual, somatosensory) exhibit higher intrinsic frequencies (0.15–0.20 Hz), while higher-order association areas (e.g., prefrontal cortex, default mode network) operate at lower frequencies (0.02–0.07 Hz). The gradients align with functional hierarchies (unimodal-to-transmodal axis), structural features (myelination, cortical thickness), and metabolic profiles, while distinguishing canonical resting-state networks by their spectral signatures.
