Tetrodotoxin is a protein toxin from puffer fish that blocks the opening of voltage-gated sodium channels at quite low doses. assume a researcher applies this drug to just the postsynaptic pair of two neurons (the presynaptic neuron we will assume is the mechanically-sensitive spinal neuron described above, and the post-synaptic cell is a relay neuron receiving input from the first cell in the spinal column). draw the response of the post-synaptic cell to three stimuli of different intensity (gentle, medium, and intense). be sure to label all axes.
