Nociception
The physiological processes related to pain perception
Mediators
Substances or factors that modulate or influence biological processes, often used in the context of physiological or pharmacological pathways.
Action Potential
A rapid, temporary change in the electrical membrane potential of a cell, essential for nerve impulse conduction.

Final Answer :
A
Explanation :
Transduction is the process by which noxious stimuli are converted into electrical signals (action potentials) that can be transmitted by nerves to the brain. During transduction, mediators such as serotonin and histamine can bind to receptors on nociceptor fibers and trigger the opening of ion channels, allowing ions to flow into the nerve and create an action potential. The other processes of nociception (transmission, modulation, perception) do not involve the use of mediators to create action potentials.
