WebApr 11, 2024 · They relate the strength and laminar pattern of cortico-cortical connections to two different factors: Euclidean distance (according to the DRM) and cortical type distance (according to the SM). If both predictive factors were correlated, the DRM and the SM would be compatible, but quite often, two cortical areas of similar cortical type are ... WebOct 30, 2024 · The figure reports the three direct systems running between the cerebral cortex and the basal ganglia (STN, GPi and SNr, shaded gray boxes), providing a fast route of connection by passing the striatum and the thalamus. Recent studies have also demonstrated that the basal ganglia communicate with the cerebellum.
