The trigger zone or axon hillock is the part of the neuron where nerve impulses originate. It is characterized by a high density of voltage-gated sodium channels which are essential for the initiation of action potentials. Therefore, this area would be the location where the fluorescent antibody would bind the most, leading to the highest level of fluorescence.
