If an electrical synapse conducted an action potential "backward" (from what would normally be the postsynaptic neuron to the presynaptic neuron), would an action potential be conducted in a retrograde direction (along the axon toward the cell body)?
a. Yes.
b. No, since the normally presynaptic neuron lacks receptors for the ions carrying current from the normally postsynaptic neuron.
c. No, since the normally presynaptic neuron would be refractory to retrograde conduction.
d. No, unless the concentration gradients for all the relevant ions were reversed.
e. No, since there's no axon hillock at the axon terminal of the normally presynaptic neuron.
A
