Topic: Sensorimotor regions

Sensorimotor regions of the neocortex send dense projections to the dorsal striatum making this region of basal ganglia an important structure of sensory integration. Anatomically, this innervation is diffuse, with axons from various cortical areas overlapping in the same striatal region. This suggests significant integration of information by striatal projection neurons (SPNs), contributing to the striatum’s role in decision making. However, the specific role of neurons forming direct and indirect pathways (d/iSPNs), as well as the level of convergence within one sensory modality onto single
