Frontostriatal circuit

Frontostriatal circuits are neural pathways that connect frontal lobe regions with the basal ganglia that mediate motor, cognitive, and behavioural programs within the brain (Alexander et al., 1986, 1990) and receive inputs from dopaminergic, serotonergic, noradrenergic, and cholinergic cell groups that modulate information processing (Tekin and Cummings, 2002). These are affected by Parkinson's disease and contribute to the non-motor symptoms associated with it.
