John Hughes and Hans Kosterlitz identified the endorphin receptor in frogs, and concluded that animals have a "built in" opioid system. To make sure that endorphins are truly neurochemicals, which of the following question should we ask these gentlemen? Please select all that apply.a) Are endorphins released in response to presynaptic depolarization?
b) Do endorphins interact with postsynaptic receptors?
c) Are endorphins found in presynaptic cells?
d) Are endorphins subject to reuptake?
Identify two neural pathways in the brain that use dopamine as a neurotransmitter, andexplain their significance.
