Below is a figure from a 2015 paper that characterizes the effect of venom from the spider Selenocosmia hainana on voltage-gated sodium channels. According to the I-V curve (current-voltage curve) in Figure panel B, what is the effect of the venom on voltage-gated sodium channels? Current is on the y-axis and voltage is on the x-axis during an action potential. The figure legend denotes the concentration of the venom being applied.
