What resolves this contention: Joel & Weiner (1994) argue for open-interconnected circuits with substantial cross-talk between motor/associative/limbic loops, contradicting the strict segregation framework; the 2020 mouse cortico-BG-thalamic mapping paper supports the higher-dimensional view, arguing the three-channel (motor/limbic/associative) model is too coarse. / Anatomical findings in primates and rodents have led to a description of several parallel segregated basal ganglia-thalamocortical circuits leading from a distinct frontocortical area, via separate regions in the basal ganglia, back to the same area. / However, given the roughly 65 cortical areas and two dozen thalamic nuclei that feed into the dorsal striatum, a three-channel view is overly simplistic for explaining the myriad functions of the basal ganglia.
