General Principles / Transduction
Transduction
DEFINITION: Conversion of stimulus energy to action potentials in primary afferent fibers
- multistep process: stimulus à accessory structures à RECEPTOR: transducer protein à ion channel à receptor potential à action potential

AUDITORY SYSTEM EXAMPLE (hair cell currents and receptor potential) |
 |
|
Transduction currents recorded from a hair cell in response to stereocilia deflection. |
Hair cell receptor potential in response to a sinusoidal stimulus. |
In the auditory system, the stages in the transduction process are:
