WebAug 8, 2024 · Neuroanatomy, Spinothalamic Tract - StatPearls - NCBI Bookshelf Frontostriatal circuits are neural pathways that connect frontal lobe regions with the basal ganglia (striatum) that mediate motor, cognitive, and behavioural functions within the brain. They receive inputs from dopaminergic, serotonergic, noradrenergic, and cholinergic cell groups that modulate information processing. … See more There are five defined frontostriatal circuits: motor and oculomotor circuits originating in the frontal eye fields are involved in motor functions; while dorsolateral prefrontal, orbital frontal, and anterior cingulate … See more The role of frontostriatal circuits is not well understood. Two of the common theories are action selection and reinforcement learning.
