Which of the following statements is true about cocaine?
O It activates dopamine receptors on a postsynaptic neuron and so acts as a direct dopamine agonist. O It blocks potassium channels, keeping the presynaptic neuron in a state of depolarization and causing increased dopamine release, acting as a direct dopamine agonist. O It blocks dopamine receptors on a postsynaptic neuron and so acts as an indirect dopamine agonist O It is a GABA agonist, causing the inhibition of neurons that normally inhibit dopamine cells. O It blocks dopamine transporters, preventing reuptake in the presynaptic neuron, and so acts as an indirect dopamine agonist.
