For review, levitra nitrates see Tzschentke, 1999). The Mesocortical Dopaminergic System 165 ICSS is performed by the animal after the operator implants a stimulating electrode into a specific brain area. D2 but not D1 receptors modulate this behavior, or D1 receptors might be necessary but not sufficient to modulate it.
Interestingly, D1 receptor antagonists do not inhibit cocaine and DA self-administration, suggesting two possibilities. If the rodent experiences the stimulation as rewarding, it will learn a simple behavior such as lever-pressing to achieve the stimulation. 1972, several studies have shown that ICSS via electrodes implanted into the PFC is performed by rodents (Routtenberg & Sloan.
There is evidence that cocaine and DA, but not other drugs of abuse, are selfadministered into the PFC, and such an effect is abolished by a specific D3 antagonist (Goeders & Smith, 1979, 1984, 1994). However, as for other addictive behaviors, the role of DA in sustaining ICSS of PFC is only partially understood.
