text: This is based on the finding that young healthy subjects given a single dose of the dopamine agonist cabergoline show reduced learning in response to gains (positive feedback), due presumably to a presynaptic effect (in low doses, cabergoline, a D 2 agonist, reduces phasic dopamine neuron firing via actions on the high affinity D 2 autoreceptor, located pre-synaptically on dopamine neurons)
