From: Model-based parametric study of frontostriatal abnormalities in schizophrenia patients
Circuit diagram of the frontostriatal system. The frontostriatal projection is glutamatergic (blue) and the axons from the striatal neurons to the midbrain DA neurons are GABAergic (red). D2 receptors are depicted at the terminals of the frontostriatal axon and the dopaminergic fiber in the striatum. Dots around the striatal neuron represent DA, which is released from the dopaminergic fiber (yellow).
