You have isolated a neurotoxin from a newly discovered snake species. When you administer the toxin to brain tissue, you can no longer record an excitatory postsynaptic potential after you experimentally stimulate the presynaptic neuron. a. Draw what the experimental setup would look like. Also include a picture of the recording you would get from the postsynaptic neuron after the  presynaptic stimulation before and after the administration of the toxin. Label your figures completely and label all axes.
