Answer #1

The action potential will not directly contribute the electrical signal outside the neuron. Action potential trigger the depolarization of post synaptic neuron by releasing chemical or electrical neurotransmitter at the site of synapse's. Hence outside neuron action potentil is not effective to measure currents

On the other hand remaining are directly contribute the current outside the neuron.
