[Krienen2009] paper:paper-80b995303060 “Human in vivo work tells the same story in a different vocabulary. Coordinate-based meta-analysis of 126 PET/fMRI studies found patterns of corticostriatal functional connectivity broadly consistent with the parallel-loop model [Postuma2005]. Resting-state fMRI in 1000 subjects partitioned the human striatum into at least five cortical zones [Buckner2011], and the cerebellum into four fronto-cerebellar circuits targ...”

[Selemon1985] paper:paper-3a2a266bc9c8 “Whether parallel channels exchange information at subcortical levels has been disputed since the schema's inception. The earliest anterograde tracing in macaque already complicated the picture: connectionally linked cortical areas projected to longitudinal medial–lateral striatal territories with relationships ranging from near-complete segregation to substantial convergence [Selemon1985, Cavada1989].

[Aoki2019] paper:paper-3023485dbad7 “The disagreement is now reframed by mesoscale data ({numref}`fig-sec7-open-vs-closed-tile`). [Foster2021] argued that mouse CBGTC subnetworks are bona fide closed loops in which thalamic domains relay back to originating corticostriatal neurons. [Aoki2019] reached the opposite verdict for the same model organism using rabies-virus tracing: ventral, dorsomedial, and tail of striatum can target M1/M2 without receiving...”

[McFarland2000] paper:paper-b3d499c61a02 “Convergence within "associative" domains is itself layered. [McFarland2000] found that interconnected motor, premotor, supplementary, and cingulate motor cortices, together with VA/VL thalamic inputs, target the same dorsal-striatal output circuits, producing an integrative motor field.
