Cocaine blocks the removal of dopamine from the synapse, leading to a rapid rise of dopamine in the synapse. Which of the following best describes what will likely occur as a result of increased dopamine in the synapse? The presynaptic cell will be unable to release more neurotransmitter. the postsynaptic cell will return to its resting potential, causing feelings of well-being. The postsynaptic cell will be constantly activated, causing feelings of euphoria. The postsynaptic cell will respond more quickly to a change in output of the presynaptic cell, causing feelings of euphoria. The buildup of neurotransmitter will activate the presynaptic cell, causing feelings of euphoria.
