Striatal system
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. Frontostriatal circuits are part of the executive functions. Executive functions include the following: selection and perception of important information, manipulation … WebMay 1, 2014 · Striatal Response to Reward Anticipation: Evidence for a Systems-Level Intermediate Phenotype for Schizophrenia Genetics and Genomics JAMA Psychiatry JAMA Network In an examination of a well-established monetary reward anticipation paradigm during functional magnetic resonance imaging, Grimm and coauthors examined …

WebFeb 20, 2024 · Striatal dopamine-depleted areas formed synchronized fMRI activity that largely corresponded to the cortico-basal ganglia motor circuit. Group comparisons revealed that striatal dopamine-depleted areas exhibited decreased FC with the medial premotor cortex during motor-task and with the medial, lateral premotor and primary motor cortices …
WebIn this study, we investigated the role of striatal D 2 R + neurons and downstream globus pallidus externa (GPe) neurons in a rat model of LID. Intrastriatal administration of raclopride, a D 2 R antagonist, significantly inhibited dyskinetic behavior, while intrastriatal administration of pramipexole, a D 2 -like receptor agonist, yielded ...
