Transduction (physiology)

Principal steps of sensory processing.

In physiology, transduction is the translation of arriving stimulus into an action potential by a sensory receptor. It begins when stimulus changes the membrane potential of a sensory receptor.

A sensory receptor converts the energy in a stimulus into an electrical signal.[1] Receptors are broadly split into two main categories: exteroceptors, which receive external sensory stimuli, and interoceptors, which receive internal sensory stimuli.[2][3]
